Labrador Retriever, a breed of domestic dog
The dog is a canine mammal of the Order Carnivora. Dogs were first domesticated from wolves at least 12,000 years ago[1] but perhaps as long as 150,000 years ago based on recent genetic fossil evidence and DNA evidence. In this time, the dog has developed into hundreds of breeds with a great degree of variation. For example, heights at the withers range from just a few inches (such as the Chihuahua) to roughly three feet (such as the Irish Wolfhound), and colors range from white to black, with reds, grays (usually called blue), and browns occurring in a tremendous variation of patterns. Dogs, like humans, are highly social animals and pack hunters; this similarity in their overall behavioral design accounts for their trainability, playfulness, and ability to fit into human households and social situations. Dogs fill a variety of roles in human society and are often trained as working dogs. For dogs that do not have traditional jobs, a wide range of dog sports provide the opportunity to exhibit their natural skills. In many countries, the most common and perhaps most important role of dogs is as companions. Dogs have lived with and worked with humans in so many roles that their loyalty has earned them the sobriquet "man's best friend." Conversely, some cultures consider dogs to be unclean. In other cultures, some dogs are used as food.
Puppies engage in teething on almost anything.
Dog, in common usage, refers to the domestic dog, Canis lupus familiaris (originally classified as Canis familiaris by Linnaeus in 1758, but reclassified as a subspecies of the wolf, Canis lupus, by the Smithsonian Institution and the American Society of Mammalogists in 1993). The word is sometimes used to refer collectively to any mammal belonging to the family Canidae (as in "the dog family"), such as wolves, foxes and coyotes.
Many additional terms are used for dogs that are not purebred;
Although selective breeding has changed the appearance of many breeds, all dogs retain the basic ingredients from their distant ancestors. Like most other predatory mammals, the dog has powerful muscles, a cardiovascular system that supports both sprinting and endurance, and teeth for catching, holding, and tearing. Its skeleton provides the ability to run and leap. They have small, tight feet, and walk on their toes.
Among dog lovers, dogs are generally valued for their intelligence. Anecdotal evidence suggests that dogs have a reasonably high intelligence. For a detailed discussion on what dog intelligence is.

Presently, there is academic discussion as to whether domestic dogs are omnivores or carnivores. The classification in the Order Carnivora does not necessarily mean that a dog's diet must be restricted to meat. Unlike an obligate carnivore, such as a cat, a dog is not dependent on meat protein in order to fulfill its dietary requirements. Dogs are able to healthily digest a variety of foods including vegetables and grains, and in fact can consume a large proportion of these in its diet. Wild canines not only eat available plants to obtain key amino acids, but may also obtain nutrients from vegetable matter from the stomach contents of their herbivorous prey. Domestic dogs can survive healthily on a reasonable and carefully designed vegetarian diet, particularly if eggs and milk products are included. Some sources suggest that a dog fed on a stict vegetarian diet may develop dilated cardiomyopathy since it lacks L-carnitine.
In the wild these diets are typically pursued in the absence of available meat. It has also been noted that extremely stressful conditions, such as the Iditarod race and scientific studies of similar conditions, suggest that high-protein diets including meat help prevent damage to muscle tissue. This research is also true of other mammals.
Dogs sometimes eat grass, a harmless activity. Explanations abound, but rationales such as that it neutralizes acid are just guesses. Eating grass might make the dog vomit, so one explanation is that dogs eat grass to remove unwanted content from their stomachs.
Many dogs consider anything given to them directly by hand to be a treat, even the food they are accustomed to at meal time. Such dogs might consider anything dropped by humans, including small but indigestible objects (such as marbles, coins, rings, etc.), to be treats as well, which could be dangerous to the dogs when ingested.
For a discussion on one use of treats in training.
Some foods commonly enjoyed by humans are dangerous to dogs, including chocolate (Theobromine poisoning), onions, grapes and raisins, Macadamia nuts, and hops. Some human medications, such as acetaminophen/paracetamol (Tylenol), are highly toxic to dogs.
Dogs also may find some poisons attractive, including antifreeze and snail bait.
Among professional breeders, dogs are only allowed to mate for a specific purpose. Sometimes dogs are bred to create puppies to sell, or sometimes to carry on an award-winning purebred line. Breeders who do this are usually experienced in this process. Dog breeders have access to records which allow them to accurately guess which characteristics will "breed true" in a particular dog. Dog breeders also have accurate information on the complexities of the reproductive process for the breed of dog that they are accustomed to handling. Dog owners may accidentally allow their pets to breed without regard to bloodlines.
As with most domesticated species, one of the first and strongest effects seen from selective breeding is selection for cooperation with the breeding process as directed by humans. In domestic dogs, one of the behaviours that is noted is the abolition of the pair bond seen in wild canines. The ability of female domestic dog to come into estrus at any time of the year and usually twice a year is also valued. The amount of time between cycles varies greatly among different dogs, but a particular dog's cycle tends to be consistent through her life. This is also called in season or in heat. Conversely, undomesticated canine species experience estrus once a year, typically in late winter.
Most bitches come into season for the first time between 6 and 12 months, although some larger breeds delay until as late as 2 years. Like most mammals, the age that a bitch first comes into season is mostly a function of her current body weight as a proportion of her body weight when fully mature. The different rates of maturation are responsible for the menarche, not the chronological age.

A general rule of thumb is that a mammal will produce half as many offspring as the number of teats on the mother. This rule is altered in domesticated animals since larger litters are often favoured for economic reasons. Dogs bear their litters roughly 9 weeks after fertilization. An average litter consists of about six puppies, though this number may vary widely based on the breed of dog. Since a mother can only provide nutrients and care to a limited number of offspring, humans must assist in the care and feeding when the litter exceeds approximately eight puppies. Some breeds have been developed to emphasize certain physical traits beyond the point at which they can safely bear litters on their own. For example, the Bulldog often requires artificial insemination and almost always requires cesarean section for giving birth.
Spaying or neutering refers to the removal of the male testicles or the female ovaries and uterus, in order to remove the capability to procreate, and to kill the libido.
Dog experts advise that dogs not intended for further breeding should be spayed or neutered so that they do not have undesired puppies. Unwanted puppies are abandoned, eaten, or sometimes disposed of in an inhumane fashion. It is also common for adult stray dogs who are placed in animal shelters to be euthanized due to lack of space and resources.
Spaying and neutering can also help prevent hormone-driven diseases such as breast cancer and prostate cancer, as well as undesired hormone-driven behaviors. The hormonal changes involved are sure to change the animal's personality somewhat, and some object to this angle as the sterilization in itself could be carried out without the excision of organs.
Contrary to myth, it is not required for a female dog to either experience a heat cycle or have puppies before spaying, and likewise, a male dog does not need the experience of mating before neutering; these myths are responsible for numerous unnecessary health problems and unwanted puppies. A female dog can become pregnant on her first heat cycle (which can take place as early as six months), and should be kept away from intact male dogs, including littermates, over the age of 4 months. Many veterinarians recommend that owners neuter/spay their pets around the age of 5 months.
Modern dog breeds show more variation in size, appearance, and behavior than any other domestic animal. Within the range of extremes, dogs generally share attributes with their wild ancestors, the wolves. Dogs are predators and scavengers, possessing sharp teeth and strong jaws for attacking, holding, and tearing their food.
Dogs were thought to be dichromats and thus, by human standards, color blind. New research is now being explored that suggests that dogs may actually see some colour, but not to the extent that humans do. It has also been suggested that dogs see in varieties of purple/violet and yellow shades. Because the lenses of dogs' eyes are flatter than humans', they cannot see as much detail; on the other hand, their eyes are more sensitive to light and motion than humans' eyes. Some breeds, particularly the best sighthounds, have a field of vision up to 270° (compared to 100° to 120° for humans), although broad-headed breeds with their eyes set forward have a much narrower field of vision, as low as 180°.
Dogs detect sounds as low as the 16 to 20 Hz frequency range (compared to 20 to 70 Hz for humans) and as high as 70,000 to 100,000 Hz (compared to 20,000 Hz for humans), and in addition have a degree of ear mobility that helps them to rapidly pinpoint the exact location of a sound. They can identify a sound's location much faster than a human can, and they can hear sounds up to four times the distance that humans can.
Dogs are predators suited to chasing after, leaping at, and killing prey. (pictured: Weimaraner)
Dogs have nearly 220 million smell-sensitive cells over an area about the size of a pocket handkerchief (compared to 5 million over an area the size of a postage stamp for humans). Some breeds have been selectively bred for excellence in detecting scents, even compared to their canine brethren. Other than the oversimplified obvious, i.e. chemical compounds that affect chemical sensors in the nose, what a dog actually detects when he is scenting is not really understood; although once a matter of debate, it now seems to be well established that dogs can distinguish two different types of scents when trailing, an air scent from some person or thing that has recently passed by, as well as a ground scent that remains detectable for a much longer period. The characteristics and behavior of these two types of scent trail would seem, after some thought, to be quite different, the air scent being intermittent but perhaps less obscured by competing scents, whereas the ground scent would be relatively permanent with respect to careful and repetitive search by the dog, but would seem to be much more contaminated with other scents. In any event, it is established by those who train tracking dogs that it is impossible to teach the dog how to track any better than it does naturally; the object instead is to motivate it properly, and teach it to maintain focus on a single track and ignore any others that might otherwise seem of greater interest to an untrained dog. An intensive search for a scent, for instance searching a ship for contraband, can actually be very fatiguing for a dog, and the dog must be motivated to continue this hard work for a long period of time.
It has been observed that a lost dog can often find its way home, sometimes traveling over long distances.
Dogs also have the ability to sense inclement weather (mainly thunderstorms) many miles away. This is due to their keen ability to detect fluctuations in barometric pressure and can explain a dog's anxiety before and during a storm. The evolutionary ability of sensing weather can be traced back to when wolves used it to move the pack into proper shelter before a dangerous storm.
Dogs are susceptible to various diseases, ailments, and poisons, some of which affect humans in the same way, others of which are unique to dogs.
Diseases commonly associated with dogs include rabies (hydrophobia), canine parvovirus, and canine distemper, and pulmonic stenosis, although there are many others.
Common external parasites are various species of fleas, ticks, and mites. Internal parasites include hookworms, tapeworms, roundworms, and heartworms.
Some breeds of dogs are also prone to certain genetic ailments, such as hip dysplasia, luxating patellas, cleft palate, blindness, or deafness. Dogs are also susceptible to the same ailments that humans are, including diabetes, epilepsy, cancer, and arthritis. Gastric torsion and bloat is a dangerous problem in some large-chested breeds.
Some dogs can be trained to retrieve
All dogs have a tremendous capacity to learn complex social behavior and to interpret varied body language and sounds, and, like many predators, can react to and learn from novel situations. The requirements of coordinating complex social behavior requires that canines have the ability to sense and deliver a wide variety of cues via body language, more so than for even humans, who can use language for the same purpose. Physiologically, this correlates with such features as a large number of nerves innervating the facial muscles of dogs, allowing subtle control of a wide variety of facial expressions; in contrast to cats, for instance, who have many fewer nerves governing their facial muscles, resulting in a smaller repertoire or "vocabulary" of expressions. This ability to read and deliver nonverbal cues makes dogs expert at reading human beings, as well, often even more so than other humans are, who rely on language. Most dog owners have a large collection of stories about their dogs recognizing individuals by their footsteps outside the door, and so on.
The relationship between dogs and humans is rooted in history and dogs coexist with humans in a variety of ways. Dogs thrive in small social groups or packs which, from their viewpoint, can include humans. Dog society can be thought of as dog packs characterized by a companionate hierarchy, in which each individual has a rank, and in which there is intense loyalty within the group. Dogs thrive in human society because their relationships with humans mimic their natural social patterns. The dog is always aware of its rank relative to other individuals in the group. An assertive dog may consider itself the alpha animal, considering its human master to be subordinate.
Many breeds of dogs, but not least German Shepherd, Labrador Retriever, and Border Collie are commonly used as working dogs. There are service dogs, guard dogs, hunting dogs, and herding dogs. Dogs have served as guides for the blind, as commandos, and have flown into outer space. Most modern working dogs are put in positions which capitalize on their sensory or strength and endurance advantages over normal humans. Dogs are also used for searching for or rescuing people and animals, such as in avalanches, at disaster sites, and for missing people or pets.
Many people compete with their dogs in a variety of dog sports, including agility, flyball, and many others. This often strengthens the bond between human and dog, since they must trust one another in a variety of environments and must learn how the other works and thinks.
Setters in particular have a long history as upland gun dogs. They have a native ability to discover and "hold" upland game birds; to freeze them momentarily on the ground with their silent, elongated pointing stance. Once the hunter approaches, at his command they will flush the birds to fly and for the hunter to shoot at.
As water dogs, the retrievers are unsurpassed. They can spend long hours in a duck blind and, after the hunter has fired at multiple ducks or geese, they can visually spot and remember the location of downed birds. At command, they dive into the icy water, swim out and retrieve the birds one by one. They can follow hand, verbal, and whistle commands at great distance as the hunter directs them to the downed bird. They typically have large, gentle muzzles to mitigate any potential damage to the game.
When trained, beagles are particularly adept at chasing through thick briars and brush after rabbits. Many hound breeds are excellent at treeing raccoons during hunting season.
Hunters with dogs report the satisfaction that the dogs seem to exhibit. Excitement is evident as they see the hunters load weapons, take to the field, and begin the hunt.

Relationships between humans and dogs are often characterized by strong emotional bonds. Consequently, dogs are popular as pets and companions, independent of any utilitarian considerations. Many dog owners consider having unconditional acceptance from a friend who is always happy to see them to be quite utilitarian, particularly if the dog also leads them to regular exercise. Empirically, dogs are quite dependent on human companionship and may suffer poor health in its absence. Many dogs are reported to have separation anxiety if their owner is away for an extended period of time.
Some research demonstrates that dogs are able to convey a depth of emotion not seen to the same extent in any other animal; this is purportedly due to their closely-knit development with modern man, and the survival-benefits of such communication as dogs became more dependent on humans for sustenance.
Nevertheless, it is often unwise to anthropomorphize the responses of dogs. Despite understandably positive interpretations by dog owners, it is questionable whether these animals are truly capable of feeling emotions on a human level. More research is needed to determine the intelligence level of dogs, and the motivations behind their responses to their masters.
Humans have a tendency to anthropomorphize animals, particularly pets such as dogs, which are generally portrayed as being "man's best friend". Animals are often given attributes such as "loyal", "cute", and "guardian", but these all have the potential to lure people into a false sense of security.
After thousands of years of domestication and selective breeding for dogs whose aggression towards humans goes no further than a ferocious bark that strongly indicates dislike of a human behavior, most dogs are unlikely to attack people. However, their sharp teeth and claws can inflict injury in an attack; a large dog can knock a human down. Provocation can range from something as seemingly innocuous as a toddler pulling a dog's tail, in which case the dog might nip to discourage the behavior, to something completely transparent to humans, such as an odor or a movement that sets a dog off, to blatant human aggression or violence towards a dog, causing it to defend itself. There are hundreds of shades of provocation that may or may not lead to an attack upon a human. Canine aggression upon humans is ordinarily not tolerated, but any human aggression against an animal having formidable means of self-defense is foolhardy in the extreme.
With formidable skills and weapons as hunters as well as large and unfussy appetites, dogs often menace livestock and wildlife. In most jurisdictions, dogs are destroyed for killing other creatures, so dogs should be prevented from any encounter with livestock or wildlife that might lead to a predatory response. The same creatures that wolves, coyotes, and foxes attack as prey, especially sheep and poultry, are similarly attractive prey to dogs.
Wild dogs are shot by farmers in an effort to protect livestock. Bodies are sometimes tied to fences as warning to other dogs, especially in rural United States and Canada. Abandoned domestic dogs who become feral are particularly dangerous; they lack the survival skills of wild canines, as well as the genetic and learned fear of the humans' world. Feral dogs often form predatory packs that attack livestock and occasionally also prove dangerous to humans.
In the UK, it is illegal to kill dogs, even if they are on your private land; you are required to contact your local Police Force, DogsTrust, or the local branch of the RSPCA, who will arrange its collection.

Molecular systematics indicate that the domestic dog (Canis lupus familiaris) descends from one or more populations of wild wolves (Canis lupus). As reflected in the nomenclature, dogs are a subspecies of wolf and are thus still able to interbreed.
The relationship between man and canine has deep roots. Wolf remains have been found in association with hominid remains dating from 400,000 years ago. Converging archaeological and genetic evidence indicate a time of domestication in the late Upper Paleolithic close to the Pleistocene/Holocene boundary, between 17,000 and 14,000 years ago. Fossil bone morphologies and genetic analysis of current and ancient dog and wolf populations have not yet been able to conclusively determine whether all dogs descend from a single domestication event, or whether dogs were domesticated independently in more than one location. Domesticated dogs may have interbred with local populations of wild wolves on several occasions (so-called introgression).
The earliest dog fossils, two crania from Russia and a mandible from Germany, date from 13,000 to 17,000 years ago. Their likely ancestor is the large northern Holarctic wolf, Canis lupus lupus. Remains of smaller dogs from Mesolithic (Natufian) cave deposits in the Middle East, dated to around 12,000 years ago, have been interpreted as descendants of a lighter Southwest Asian wolf, Canis lupus arabs. Rock art and skeletal remains indicate that by 14,000 years ago, dogs were present from North Africa across Eurasia to North America. Dog burials at the Mesolithic cemetery of Svaerdborg in Denmark suggest that in ancient Europe dogs were valued companions.
Genetic analyses have so far yielded divergent results. Vilà, Savolainen, and colleagues (1997) concluded that dogs split off from wolves between 75,000 and 135,000 years ago, while a subsequent analysis by Savolainen et al. (2002) indicated a "common origin from a single gene pool for all dog populations" between 40,000 and 15,000 years ago in East Asia. Verginelli et al. (2005), however, suggest both sets of dates must be reevaluated in light of recent findings showing that poorly calibrated molecular clocks have systematically overestimated the age of geologically recent events. On balance, and in agreement with the archaeological evidence, 15,000 years ago is the most likely time for the wolf-dog divergence.
Verginelli examined ancient DNA evidence from five prehistoric Italian canids carbon-dated to between 15,000 and 3,000 years old, 341 wolves from several populations worldwide, and 547 purebred dogs. Their results indicate multiple independent origins of dogs and/or of frequent interbreeding between early proto-dogs and wolves throughout a vast geographic range. The detailed history remains unexplored and until further evidence is available, the following section on wolf ancestors must be considered purely speculative.
Although all wolves belong to the species Canis lupus, there are (or were) many subspecies that had developed a distinctive appearance, social structure, and other traits. For example, the Japanese wolf and the Eastern Timber Wolf posses different distinctive colouration, hunting and social structures.
The Indian Wolf is thought to have contributed to the development of more breeds of dogs than other subspecies. Many of today's wild dogs, such as the dingo, the dhole and pariah dogs, are descended from this wolf.
The Indian wolf is also thought to have bred with descendants of the European wolf to create the Mastiffs and eventually leading to the development of such diverse breeds as the Pug, the Saint Bernard, and the Bloodhound. The Tibetan Mastiff is an example of an ancient breed.
The European wolf, in turn, may have contributed many of its attributes to the Spitz dog types, most terriers, and many of today's sheepdogs. The Chinese wolf is probably ancestor to the Pekingese and toy spaniels, although it is also probable that descendants of the Chinese and European wolves encountered each other over the millennia, contributing to many of the oriental toy breeds.
The Eastern Timber Wolf is a direct ancestor to most, if not all, of the North American northern sled dog types. This interbreeding still occurs with dogs living in the Arctic region, where the attributes of the wolf that enable survival in a hostile environment are valued by humans. Additionally, unintentional crossbreeding occurs simply because dogs and wolves live in the same environment. The general reproductive isolation which is required to define dogs and wolves as separate species is purely a result of lack of opportunity, stemming from a general mutual unfamiliarity, suspicion, mistrust, and fear.
The phenotypic characteristic that distinguish a wolf from a dog are tenuous. Wolves typically have a "brush tail" and erect ears. While some dog breeds possess one of these characteristics, they rarely possess both.
Current research indicates that domestication, or the attributes of a domesticated animal, can occur much more quickly than previously believed. Domestication of a wild dog may occur within one or two human generations with deliberate selective breeding. It is also now generally believed that initial domestication was not attained solely by human desire intervention but through mutual desire. Wild canines who scavenged around human habitations received more food than their more skittish or fearful counterparts. Canines who attacked people or their children were likely killed or driven away, while those more friendly animals survived. Canines would have been beneficial by chasing away other vermin or scavengers. With their sharp senses, they would also be valuable as an alarm against marauding predators. The relationship is theorized to have developed in this way.
There are numerous dog breeds, over 800 being recognized by various kennel clubs worldwide. As all dog breeds have been derived from mixed-breed dog populations, the term "purebred" has meaning only with respect to a certain number of generations. Many dogs, especially outside the United States and Western Europe, belong to no recognized breed.
A few basic breed types have evolved gradually during the domesticated dog's relationship with man over the last 10,000 or more years, but most modern breeds are of relatively recent derivation. Many of these are the product of a deliberate process of artificial selection. Because of this, some breeds are highly specialized, and there is extraordinary morphological diversity across different breeds. Despite these differences, dogs are able to distinguish dogs from other kinds of animal.
The definition of a dog breed is a matter of some controversy. Some groups use a definition that ultimately requires extreme inbreeding to qualify due to the low gene pool. Dogs that are bred in this manner often end up with severe health or behavioural problems. Other organizations define a breed more loosely, such that an individual may be considered of one breed as long as 75% of its parentage is of that breed. These considerations come into play among breeders who enter their dogs in dog shows. Even prize-winning purebred dogs sometimes possess crippling genetic defects due to inbreeding. These problems are not limited to purebred dogs and can affect mixed-breed populations. The behavior and appearance of a dog of a particular breed can be predicted fairly accurately, while mixed-breed dogs show a broader range of innovative appearance and behavior.
In February 2004, the Canine Studies Institute in Aurora, Ohio, arranged recognized breeds of dogs into ten categories.
Mixed-breed dogs or Mongrels are dogs that do not belong to specific breeds, being mixtures of two or more in variant percentages. Mixed breeds, or dogs with no purebred ancestry, are not inherently "better" or "worse" than purebred dogs as companions, pets, working dogs, or competitors in dog sports. Sometimes mixed-breed dogs are deliberately bred, for example, the Cockapoo, a mixture of Cocker Spaniel and Miniature Poodle. Such deliberate crosses may display hybrid vigor and other desirable traits, but can also lack one or more of the desired traits of their parents, such as temperament or a particular color or coat. However, without genetic testing of the parents, the crosses can sometimes end up inheriting genetic defects that occur in both parental breeds. Deliberately crossing two or more breeds is also a manner of establishing new breeds.
This rapid evolution of dogs from wolves is an example of neoteny or paedomorphism. As with many species, the young wolves are more social and less dominant than adults; therefore, the selection for these characteristics, whether deliberate or inadvertent, is more likely to result in a simple retention of juvenile characteristics into adulthood than to generate a complex of independent new changes in behavior. This is true of many domesticated animals, including human beings themselves, who have many characteristics similar to young bonobo. This paedomorphic selection naturally results in a retention of juvenile physical characteristics as well. Compared to wolves, many adult dog breeds retain such juvenile characteristics as soft fuzzy fur, round torsos, large heads and eyes, ears that hang down rather than stand erect, etc.; characteristics which are shared by most juvenile mammals, and therefore generally elicit some degree of protective and nurturing behavior cross-species from most adult mammals, including humans, who term such characteristics "cute" or "appealing".
The example of canine neoteny goes even further, in that the various breeds are differently neotenized according to the type of behavior that was selected.
Of course, dogs in general possess a significant ability to modify their behavior according to experience, including adapting to the behavior of their "pack leaders"—again, humans. This allows them to be trained to behave in a way that is not specifically the most natural to their breed; nevertheless, the accumulated experience of thousands of years shows that some combinations of nature and nurture are quite daunting, for instance, training whippets to guard flocks of sheep.

In the animal breeding, to breed true means that specimens of an animal breed will breed true-to-type when mated like-to like; that is, that the progeny of any two individuals in the same breed will show consistent, replicable and predictable characteristics. A puppy from two purebred dogs of the same breed, for example, will exhibit the traits of its parents, and not the traits of all breeds in the subject breed's ancestry.

Canid hybrids are the result of interbreeding between two different members of the canine family (Canidae).
Many members of the dog family can interbreed to produce fertile offspring.
Molecular analysis indicates 4 divisions of canids:
The wolf, coyote, jackal, and domestic dog (including the dingo) all have 78 chromosomes arranged in 39 pairs. This allows them to hybridise freely (barring size or behavioural constraints) and produce fertile offspring. The wolf, coyote, and golden jackal diverged around 3 to 4 million years ago. Other members of the dog family diverged 7 to 10 million years ago and are less closely related and connot hybridise with the wolf-like canids: the yellow Jackal has 74 chromosomes, the red fox has 38 chromosomes, the raccoon dog has 42 chromosomes, and the Fennec fox has 64 chromosomes. Although the African Wild Dog has 78 chromosomes, it is considered distinct enough to be placed in its own genus.
(Note: It may be that foxes cannot hybridize with dogs but, as crosses between horses and zebras demonstrate, differences in chromosome number are not the reason. Viable hybrids between species are possible regardless of chromosome number differences provided the gene combination in the hybrid allows for embryonic development to birth. Large differences in chromosome number, however, would make hybrid bitches so poorly fertile as to be essentially sterile. Male hybrids would be sterile due to a phenomenon called Haldane's Rule.)
In The Variation Of Animals And Plants Under Domestication, Charles Darwin wrote:
In Darwinism An Exposition Of The Theory Of Natural Selection With Some Of Its Applications (1889), Alfred Russel Wallace commented:
(Note: this deterioration was probably the result of inbreeding among the hybrid offspring)
Dog hybrids kept as pets are prohibited in many jurisdictions or are classed as wild animals and must be housed in the same way as purebred wolves. For example, hybrids of the domestic dog with the wolf, coyote, dingo, jackal, fox, dhole, African Wild Dog, or Raccoon dog are prohibited in the State of Hawaii (this legislation does not take into account the impossibility of some of the hybrids listed).
People wanting to improve domestic dogs have sometimes bred them back to wolves. This compensates for inbred genetic problems in domestic dogs, but wolf-dog hybrids are dominant in adulthood and less domesticable. Grey wolves have been crossed with wolf-like dogs such as German Shepherd Dogs and Alaskan Malamutes. Many problems occur because the owner expects them to behave like a domestic dog and is unaccustomed to wolf-type behaviour. In parts of Europe, the declining wolf population naturally hybridises with stray and feral domestic dogs, resulting in mongrel populations and further endangering the natural wolf.
There are a number of wolf-dog hybrid breeds in development, for example, the Saarlooswolfhond breed is possibly derived from wolf-dog hybrids. The initial hybrid offspring are generally back-crossed to domestic dogs to maintain a domestic temperament and consistent conformation. First-cross wolf-dog hybrids are popular in the USA, but retain many wolf-like traits.
Contrary to popular myth, dogs cannot successfully interbreed with red foxes. Dogs have 78 chromosomes, but red foxes have only 38 chromosomes. This severe mismatch is a barrier to hybridisation.
An unconfirmed female terrier/fox hybrid was reported (and later euthanized) in the UK. British gamekeeper folklore claims that Terrier bitches can produce offspring with dog Foxes. The supposed hybrids (known as a dox) are natural variation in the domestic dog. There has been a reported cross between a domestic dog and a South American fox, but the latter was a fox-like wolf and not a true fox.
In Saskatchewan, Canada there was another reported dox, this time a female miniature sheltie with a wild fox. There was a litter of three, but only one survived. The surviving (a female) was sterile, and looked like an almost pure fox, with slight variations.
In Origin of Species (1859), Charles Darwin wrote:
Coy-dogs (male coyote/female dog) can occur naturally as female coyotes are more likely to meet male dogs than meet male coyotes. Coydogs were once believed to be present in large numbers in Pennsylvania due to a declining Coyote population and a burgeoning domestic dog population. Most supposed hybrids were naturally occurring red or blond color variations of the Coyote or were feral dogs. The breeding cycles of dogs and coyotes are not synchronized and this makes interbreeding uncommon. If interbreeding had been common, each successive generation of the Coyote population would have acquired more and more dog-like traits.
Coyotes are solitary by nature and this trait is carried across to coyote-dog hybrids. This can result in problematical and unsociable behaviour which makes them generally unsuited as pets. As a result, they may be abandoned or allowed to stray and be absorbed into the feral dog or coyote population.
Coyotes have also been crossed with Australian dingoes in zoological gardens.
The Australian Dingo (a feral, rather than wild, species) hybridises freely with domestic dogs. This is now so widespread that many dingoes are now mongrels. Some dingo hybrids have been deliberately bred as pets, but are turned loose due to behavioural problems. These hybrids are accepted back into the wild dingo population where they breed with pure dingoes. In some parts of Australia, up to 80% of dingoes are hybrids. Dingoes are distinguishable from domestic dogs through DNA and through having longer teeth and longer muzzles.
The Australian Kelpie sheepdog is widely believed to be a hybrid of dingo and Border Collie, but this is not upheld by breed documentation.
The mating of a male dog and a female coyote results in a Dogote. There has been one report of a Dogote which arose from a male German Shepherd/female coyote mating in the wild. Hybrid pups were found after a female coyote was shot. The adult Dogotes resembled a German Shepherd in color.
Coyotes are solitary by nature and this trait is carried across to dog-coyote hybrids resulting in problematical or unsociable behaviour.
Coy-wolves (Coyote/Wolf) have occurred in captivity or, rarely, in the wild where the choice of same-species mates has been limited. Coyote/Red Wolf hybrids have been found. Some consider that the American Red Wolf is not a true species because it can hybridize with both the Grey Wolf and the Coyote; however, it is now known that hybridization between species (in general) happens more often than previously thought. Some consider it a Grey Wolf/Coyote hybrid and use this argument to prevent conservation of the Red Wolf. Some hybridization occurred when pure Red Wolves were in decline and interbred with the more numerous Coyotes. The species boundary is often preserved by geographic or behavioural separation, not by genetic separation.
The Wolf and Jackal can interbreed and produce fertile hybrid offspring. Coyote/Jackal Hybrids have also been bred as pets by Wolf-dog enthusiasts. Dogs have been crossed with golden jackals; however, they cannot produce fertile offspring with yellow jackals as the latter have only 74 chromosomes compared to 78 in the dog. It is also thought that Pharoanic Egyptians crossbred domestic dogs with jackals, producing a jackal-dog that resembled the god Anubis.
(Note: Wild horses have 66 chromosomes. Domestic horses have 64. Wild horses and domestic horses can interbreed and produce fertile hybrids. The reason golden jackals differ in chromosome number is most likely because golden jackals have 2 pairs of chromosomes that are twice as long but contain similar gene content as 4 pairs of dog chromosomes. This might reduce fertility but it would not likely completely sterilize golden jackal-dog hybrids.)
In The Variation Of Animals And Plants Under Domestication Charles Darwin wrote:
In Russia, Dog/Jackal hybrids were bred as sniffer dogs because Jackals have a superior sense of smell and Huskies are good cold climate dogs. As well as a superior sense of smell, important at low temperatures where substances are less volatile and therefore less pungent, Sulimov Dogs are small sized and can work in confined spaces. When tired, their normally curled tails droop, making it clear to the handler that the dog needs to be rested.
The jackal hybrids were bred by senior researcher Klim Sulimov at the D.S. Likhachev Scientific Research Institute for Cultural Heritage and Environmental Protection in Russia.
Male Jackal pups had to be fostered on a Husky bitch in order to imprint the Jackals on dogs. Female Jackals accepted male Huskies more easily. The half-bred Jackal-Dogs were hard to train and were bred back to Huskies to produce quarter-bred hybrids (quadroons). These hybrids were small, agile, trainable and had excellent noses. They are called Sulimov Dogs after their creator and may one day be registered as a working breed of dog. Twenty-five jackal-dog hybrids are used by Aeroflot at Sheremetevo Airport in Moscow.

A coydog, or dogote as they are sometimes called, is the hybrid offspring of a coyote (Canis latrans) and a dog (Canis lupus familiaris). Together they are genetically capable of producing fertile young.
The result of a male dog and a female coyote is a dogote, while the result of a male coyote and a female dog is a coydog. There IS a difference where the cross-breeding of animals is concerned. The male of the species tends to give the first part of the offspring's name.
Coydogs are fairly rare in the wild, in part because female coyotes are fertile for only about 60 days out of the year. Nevertheless, they are born sometimes. Wild coydogs can cause major problems for humans, as they typically have all the infamous cunning of coyotes but lack coyotes' natural fear of humans. A German Shepherd/female coyote dogote litter was found after a female coyote was shot. The adult Dogotes resembled German Shepherds in colour.
Coydogs were once believed to be present in large numbers in Pennsylvania due to Coyotes being in decline and domestic dogs being available as mates. Most were probably naturally occurring red or blonde Coyotes or were feral dogs. If interbreeding between the species really were common, the Coyote population would acquire more dog-like traits with each successive generation. Coyotes have also been crossed with Australian dingos.
Coyotes also breed with wolves, resulting in Coy-Wolves. Coyote/Red Wolf hybrids have also been found. Some zoologists do not consider the American Red Wolf to be a true species since it can hybridize with both the Grey Wolf and the Coyote. The argument that it is a Grey Wolf/Coyote hybrid prevents conservation efforts.

The anatomy of dogs varies tremendously from breed to breed, more than in any other animal species, wild or domesticated. And yet there are basic physical characteristics that are identical among all dogs, from the tiny Chihuahua to the giant Irish Wolfhound.
Like most predatory mammals, the dog has powerful muscles, a cardiovascular system that supports both sprinting and endurance, and teeth for catching, holding, and tearing.
The dog's ancestral skeleton provided the ability to run and leap. Their legs are designed to propel them forward rapidly, leaping as necessary, to chase and overcome prey. Consequently, they have small, tight feet, walking on their toes; their rear legs are fairly rigid and sturdy; the front legs are loose and flexible, with only muscle attaching them to the torso.
Although selective breeding has changed the appearance of many breeds, all dogs retain the basic ingredients from their distant ancestors. Dogs have disconnected shoulder bones (lacking the collar bone of the human skeleton) that allow a greater stride length for running and leaping. They walk on four toes, front and back, and have vestigial dewclaws (dog thumbs) on their front and rear legs just like monkeys' thumbs. In some cases these claws are missing due to surgery, the rear dewclaws sometimes being removed to prevent the possibility of them being ripped off, or catching on something and breaking, especially in dogs with loose dewclaws. This practice is illegal in some countries.
The dog's ancestor was about the size of a Dingo, and its skeleton took about 10 months to mature. Today's toy breeds have skeletons that mature in only a few months, while giant breeds such as the Mastiffs take 16 to 18 months for the skeleton to mature. Dwarfism has affected the proportions of some breeds' skeletons, as in the Basset Hound.
Puppies often have characteristics that do not last beyond early puppyhood. Eye color often changes from blue to its adult color as the puppy matures. The coat color may change: Kerry Blue Terrier puppies have black coats at birth and change to blue with maturity, and Dalmatians are white and gain their spots with age. The ear shape will also often change, especially with erect-eared breeds such as the German Shepherd Dog which have soft ears at birth, but the cartilage strengthens with age.
It is not uncommon for puppies to have their ears cropped or straightened, tails docked, or in the case of the Chow Chow, to have their eyefolds stitched back so that they can see. Many of these are done in accordance with breed standards for many Kennel Clubs. Some countries like Italy have banned this practice as an act of animal cruelty.
A common misconception is that dogs do not sweat. Primarily, dogs regulate their body temperature in a completely different way, through their tongue. That is why after a dog has been running or on a hot day, its mouth will be seen wide open with the tongue hanging out. This form of cooling maximizes heat lost while conserving moisture, because it carries heat from the hottest part of the body, the interior core of the thorax, unlike sweating, which cools the already coolest part of the body, the skin—or in less intuitive, more scientific terms, this higher efficiency of thermal loss relative to moisture conservation arises because heat flow is proportional to temperature gradient. In addition, dogs effectively sweat through the pads of their feet, since they are not furred. On a warm day and after exercise, a dog's naturally wet footprints might be visible on a smooth floor.
Dogs possess a rete mirabile in the carotid sinus at the base of their neck, a complex of intermingled small arteries and veins which acts as a heat exchanger to thermally isolate the head, containing the brain, the most temperature-sensitive organ, from the body, containing the muscles, where most of the heat is generated. The result is that dogs can sustain intense physical exertion over a prolonged time in a hot environment, compared to animals which lack this apparatus; thus, a dog chasing a jackrabbit through the desert may not be able to outrun the rabbit, but it can continue the chase until the rabbit literally drops dead from overheating.

Coat colors range from pure white to solid black and many other variations.
Dogs exhibit a diverse array of coat textures, colors, and markings, and a specialized vocabulary has evolved to describe them.
Originally, dogs all had dense fur with an undercoat and long muzzles and heads, although both of these features have been altered in some of the more extremely modified breeds, such as the Mexican Hairless Dog and the English Bulldog.
One often refers to a specific dog first by coat color rather than by breed; for example, "a blue merle Aussie" or "a chocolate Lab". Coat colors include:
The Dalmatian's coat is one of the more widely recognized markings.
Coat patterns include:
Coat textures vary tremendously. Some coats make the dogs more cuddly and others make them impervious to cold water. Densely furred breeds such as most sled dogs and Spitz types can have up to 600 hairs per inch, while fine-haired breeds such as the Yorkshire Terrier can have as few as 100, and the "hairless" breeds such as the Mexican Hairless have none on parts of their bodies. The texture of the coat often depends on the distribution and the length of the two parts of a dog's coat, its thick, warm undercoat (or down) and its rougher, somewhat weather-resistant outer coat (topcoat, also referred to as guard hairs). Breeds with soft coats often have more or longer undercoat hairs than guard hairs; rough-textured coats often have more or longer guard hairs. Textures include:
The German Wirehaired Pointer's coat demonstrates a rough texture.

A special vocabulary has been developed to describe the shapes of various body parts including the ears and tail.
Dogs' ears come in a variety of sizes, shapes, lengths, positions on the head, and amounts and types of droop. Every variation has a term, including:
The Basset Hound's ears are extremely long drop ears.
Like ears, tails come in a tremendous variety of shapes, lengths, amounts of fur, and tailsets (positions). Among them:
Puppies often have characteristics that do not last beyond early puppyhood. Eye color often changes from blue to its adult color as the puppy matures.

Dog breeding is the vocation of mating carefully selected specimens of the same breed to reproduce specific, consistently replicable qualities and characteristics.
At its best, breeding is a blend of science and art. The skilled breeder has at least general knowledge of genetics and health, and in-depth knowledge of the breed standard and conformation points of his chosen breed. Most breeders are fiercely loyal to their dogs, and are concerned about each individual animal.
At worst, breeding can be a slipshod enterprise in which the major concern is profit, with little regard to the health and welfare of the dogs involved. These often take the form of so-called ‘backyard breeders’ (the term for random or ignorant breeding conducted on a small scale), and ‘puppy mills’ or ‘puppy farms’ (larger businesses). It must be pointed out, however, that many excellent breeders run small-scale programs in their homes, barns, or back yards, and there are profitable large-scale operations run with knowledgeable staff and superlative veterinary care, so size and motive alone are not indicative of the quality of the breeding program.
The birth of a litter of purebred puppies is recorded on a breed registry maintained by an all-breed kennel club or a breed club. Such registries are not the exclusive province of show dogs, as is sometimes thought; the clubs of working dogs also maintain records of their dogs’ lineage.
A responsible breeder checks each puppy for health and conformation.
Requirements for the breeding of registered purebreds vary from club to club. Most breed clubs allow for any registered puppy to be bred from once it reaches a suitable age. Some clubs maintain an adjunct or limited register, for puppies of purebred parents not deemed to have the qualities for showing or breeding, or who exhibit a fault. A few clubs, such as the Swiss breed club of the Greater Swiss Mountain Dog, the Jack Russell Terrier Club of America and the Mini Foxie Club of Australia, Inc. have additional, strict requirements for the certification of adult dogs before breeding.
Snuppy, the first cloned dog, shows that it is possible to produce a dog that is the genetic twin of another dog, although it is still difficult and expensive to do so. It is possible that, in the future, it might be possible, and some people might choose, to create a twin of their favorite pet or of an admired champion dog rather than to adopt a dog or to wait for the outcome of a mating between two preferred parents. If taken to an extreme, this would mean that people would be able to review photos of breed champions, read their descriptions, and choose one to duplicate, which would be cloned on demand.

A backyard breeder is a person who practices random or ignorant dog breeding on a small scale. The name is something of a misnomer, as many excellent breeders run small-scale programs in their houses, garages, barns, or backyards
The term is meant to refer to people who are ignorant of selective breeding goals and techniques, and are not familiar with the breed standard of their chosen breed of dog. Backyard breeders are motivated by the idea of profit, not realizing that the hobby of animal breeding practiced on a small scale is not usually profitable when one factors in costs such as health, maintenance and pregnancy care. People who have not considered these factors often stint their breeding stock in terms of veterinary care and adequate maintenance, the puppies they produce may have genetic disorders or undisclosed illnesses; it is these people who are disparaged as 'backyard breeders'.
When such breeding is carried out on a large scale, the venue is called a puppy mill (or puppy farm in Commonwealth English).

Dogs have been selectively bred for thousands of years. Initially the selections would have centred on domestication and useful qualities such as hunting ability. Later, dogs were also selected to give attractive and distinctive forms resulting in a vast variety of types. The point at which a new variety becomes a breed can be difficult to decide. National kennel clubs often differ in their recognition of breeds and rare breeds might not be recognised outside their home country. Usually, only dogs recognized by a kennel club are eligible to compete in the club's dog shows and dog sports, although many dog sports allow any healthy dog to compete regardless of the breed.
Many traditional dog breeds recognised by the main registries are said to be "purebred". Only individuals whose parentage consists only of other purebred examples of the breed are regarded as part of that breed. This concept has caused controversy both because of the difficulty of regulation and because of the possible genetic consequences of a limited population. Recent work has been done to genetically classify the various breeds, with some surprising results regarding the estimated age and interrelations of the breeds.
Generally, before a type of dog is recognized as a breed, it must be shown that mating a pair of that type always produces dogs that have the same characteristics as the parents, usually both in appearance and in behavior. This is known as breeding true. There are many issues concerning what is considered breeding true. For example, Flat-Coated Retrievers must always be black; however, yellow coats occur occasionally in some litters. Kennel clubs do not recognize the yellow dogs as legitimate members of the breed; some breeders will euthanize the puppies rather than risk having the dog grow up, breed, and produce more of the undesired yellow color; more often, today, such dogs are neutered and placed in homes as pets. As another example, a breeding pair of Belgian Shepherds of the Groenendael variety can produce puppies of the Tervueren (brown) variety; the AKC considers the varieties to be different breeds and, therefore, the brown puppies are invalid and undesirable dogs, whereas the CKC considers them simply to be different varieties.

Dogs have been selectively bred for thousands of years, sometimes by inbreeding dogs from the same ancestral lines, sometimes by mixing dogs from very different lines. The process continues today, resulting in a tremendous variety of dog breeds.
The following list uses a wide interpretation of "breed". Breeds listed here may be traditional breeds with long histories as registered breeds, rare breeds with their own registries, or new breeds that may still be under development. Please see individual articles for more information.
This Chihuahua mix and Great Dane show some of the tremendous variety of dog breeds.
Dog breeds can be divided into different categories, such as:
Dog breeds can also be grouped into similar types such as mastiff types, spitz types, pit bulls, or Lurchers.

The Affenpinscher is a terrier-like toy breed of dog.
Weighing 7 to 8 pounds (3-4 kg) and not exceeding 10.25 inches (26-27 cm) in height at the withers, the Affenpinscher has bushy eyebrows, shaggy hair, and a monkey-like appearance. The coat is medium long and is harsh and wiry in texture. The FCI breed standards specifies that the coat must be black, but the AKC also allows gray, silver, red, black and tan, and beige; other clubs have their own lists of acceptable colours, with black always being the preference.
Affenpinschers have an appearance that some associate with terriers. They are different from terriers, however, in that they are actually part of the pinscher-schnauzer subgroup of group 2 in the FCI classification so often get along with other dogs and pets. They are active, adventurous, curious, and stubborn, but they are also fun-loving and playful. The breed is confident, lively, affectionate towards family members and also very protective of them. This loyal little dog enjoys being with its family. It needs consistent, firm training because some can be quite difficult to housebreak. The training should be varied because the dog can easily become bored.
Affenpinschers are somewhat territorial when it comes to their toys and food, so they are not recommended for very small children. This dog is mostly quiet but can become very excited if attacked or threatened and shows no fear toward any aggressor. It is best suited for a family who likes a show and has a sense of humor.
The breed can be expected to live about 14-15 years. It is one of the healthiest breeds, with no known genetic health problems.
The breed is European in origin and dates back to the seventeenth century. Its name is derived from the German affe ("ape", "monkey") and pinscher ("terrier"). The breed predates and is ancestral to the Griffon Bruxellois (Brussels Griffon) and Belgian Griffon. Dogs of the Affenpinscher type have been known since about 1600 but these were somewhat larger, about 12 to 13 inches, and came in colors of gray, black, fawn, black and tan, gray and tan, and even red. White feet and chest were also common. The breed was created to be a ratter, working to remove rodents from kitchens, granaries, and stables.

Bandog is derived from early English and refers to a ferocious large type of dog that was bound by a chain until it was released at night in order to guard property. The fact that the modern day Bandog is also large, can be ferocious, and is composed of some Mastiff and some Bulldog, as was the original Bandog, is all that the Bandog of old and the modern Bandog have in common.
The Bandog is a large dog ranging in weight from about 100 to 150 lbs and roughly 26 inches at the withers.
In the early 1970s the late veterinarian, John Swinford D.V.M., began a breeding program, which was ultimately to produce the greatest of all protection dogs. Though breeders of Bandogs today disagree on just what breeds went into Swinford's original breeding scheme, the consensus is that it was 50 percent American Pit Bull Terrier and 50 percent "very large dog". Unfortunately, Swinford died at an early age and his Bandog was never perfected or recognized as a purebred.
Contemporary Bandogs are bred with different types of dogs, including American Pit Bull Terrier with either a Mastiff, Neapolitan Mastiff, or Bull Mastiff. Whichever breeding plan is employed, it is necessary to cross the American Pit Bull Terrier to one of these Mastiffs each time that a litter of Bandogs is desired.
The obvious question that arises is: why don't breeders simply cross Bandogs with other Bandogs?
The answer is that, at this stage of Bandog development, when one crosses a Bandog to a Bandog, one does not get a Bandog. Bandogs do not breed true yet and it seems that Bandog breeders are far from having perfected a purebred dog.
The hope is that the breeding of these dogs will finally be perfected; however, the dog is being bred by many breeders who range from the very serious and knowledgeable to the very amateurish and inexperienced, sometimes called backyard breeders. Therefore, a purchaser of a Bandog must do a good deal of investigation to avoid the risk of buying a puppy that will grow to become the last thing wanted in a pet.
Bandogs are occasionaly used fighting dogs. When a fight between a Pit Bull Terrier and a Bandog occurs, the Bandog typically dominates the first 10 minutes of the fight as the Pit Bull is overpowered by the much larger Bandog. If the Pit Bull remains able to continue, it normally reverses the tables with its better endurance. Some argue that this shows that a 45- to 50-pound Pit Bull is the ideal size for fighting. Pitbull Neo mixes or Pitbull Tosa mixes are prefferred because thay are more able breeds than the larger,clumsier English mastiffs.
The non-dogfighter who is in the market for a great family dog that will be an intruder's nightmare can consider the Bandog.

The Cairn Terrier is a breed of dog of the terrier category. It is one of the oldest terriers, originating in the Scottish Highlands, used for hunting burrowing prey among the cairns.
Cairns stand between 9 and 13 inches (23-33 cm) at the withers and weigh 13 to 18 pounds (6 to 8 kg). European Cairns tend to be larger than American Cairns and, because puppy mills do not care about breed standards, many Cairns available today are much smaller or much larger than the breed standard. Cairns that have had puppy-mill backgrounds can weigh as little as 7 pounds or as much as 27 pounds.
The Cairn Terrier has a harsh, weather-resistant outer coat that can be cream, wheaten, red, sandy, gray, or brindled in any of these colors. Pure black, black and tan, and white are not permitted by many kennel clubs. While registration of white Cairns was once permitted, after 1917 the American Kennel Club required them to be registered as West Highland White Terriers. A notable characteristic of Cairns is that brindled Cairns frequently change color throughout their lifetime. It is not uncommon for a brindled Cairn to become progressively more black or silver as it ages. The Cairn is double-coated, with a soft, dense undercoat and a harsh outer coat. A well-groomed Cairn has a rough-and-ready appearance, free of artifice or exaggeration.
Cairn Terriers are intelligent, strong, loyal and fearless. Like most terriers, they are stubborn and strong-willed, and love to dig after real or imagined prey. Cairn Terriers have a strong prey instinct and will need comprehensive training. However, they are highly intelligent and, although very willful, can be trained. Although it is often said that they are disobiedient, this is not the case provided correct training is applied. They are excellent with children and make wonderful family dogs. These are working dogs and are still used as such in parts of Scotland. Like most terriers, they require large amounts of exercise.
These dogs are generally healthy but many have allergies. Often the allergies take the form of skin conditions. Corn is often the culprit, so an owner of a Cairn Terrier should routinely try to avoid feeding foods and treats that contain corn. Even if the Cairn does not show symptoms of corn allergy, because corn allergies are so prevalent and can show up at any time in the life of the dog, it is recommended to avoid corn even with a healthy dog.
This breed also suffers more than usual from dislocated kneecaps and inherited eye diseases. Ocular Melanosis (OM) is an eye disease that is found almost exclusively in Cairns.
Health problems are more common with US strains. UK Cairns tend to be less highly bred and less susceptible to most of the listed problems.
The dog named Toto in the 1939 screen adaptation of The Wizard of Oz is a Cairn Terrier.

The Dachshund is a short-legged, elongated dog breed of the hound family. The breed's name is German and literally means "badger dog" (der Dachs - badger; der Hund - dog). The breed was developed to scent, chase, hunt, and kill badgers and other hole-dwelling animals. Due to their long, narrow build, they are sometimes referred to in the United States and elsewhere as "wiener dogs" or "sausage dogs".
A full-sized Dachshund averages 12 to 24 lb (5 to 10 kg), while the Miniature variety typically weighs less than 12 lb (5 kg). Modern Dachshunds are characterized by their crooked legs, loose skin and barrel-like chest, attributes that were deliberately added to the breed to increase their ability to burrow into tight spaces. They come in three coat varieties: Smooth, Longhaired and Wirehaired; the Wirehaired variety is generally shorter in spine length than the other two. H. L. Mencken said that "A dachshund is a half-dog high and a dog-and-a-half long," which is their main claim to fame.
Dachshunds are loyal, playful fun dogs, known for their propensity to chase small animals and birds. According to the American Kennel Club's breed standards, "the Dachshund is clever, lively and courageous to the point of rashness, persevering in above and below ground work, with all the senses well-developed. Any display of shyness is a serious fault."[1] Individuals which are indulged may become snappy[2]. Coat type is often considered to be associated with characteristic temperaments; the long-haired variety, for instance, is considered to be less excitable than the other types because it was cross-bred with the Spaniel to obtain its characteristic long coat. Some who own long-haired Dachshunds might disagree with this statement, however. Because of the breed's characteristic barrel-like chest, the dachshund's lungs are unusually large, making for a sonorous bark.
The breed is known to have spinal problems, due in part to an extremely long spinal column and short rib cage. The risk of injury can be worsened by obesity, which places greater strain on the vertebrae. In order to prevent injury, it is recommended that Dachshunds be discouraged from jumping and taking stairs. It has become increasingly apparent that the occurrence and severity of these problems is largely hereditary, and responsible breeders are working to eliminate this characteristic in the breed.
Some have theorized that the early roots of the Dachshund go back to Ancient Egypt, where engravings were made featuring short-legged hunting dogs. But in its modern incarnation, the Dachshund is a creation of European breeders, and includes elements of German, French and English hounds and terriers. Dachshunds have been kept by royal courts all over Europe, including that of Queen Victoria, who was particularly enamored of the breed.
The first verifiable references to the Dachshund, originally named the "Tachs Kriecher" (badger crawler) or "Tachs Krieger" (badger catcher), come from books written in the early 1700s. Prior to that, there exist references to "badger dogs" and "hole dogs", but these likely refer to purposes rather than to specific breeds. The original German Dachshunds were larger than the modern full-size variety, weighing between 30 and 40 lb (14 to 18 kg), and originally came in straight-legged and crook-legged varieties (the modern Dachshund is descended from the latter). Though the breed is famous for its use in exterminating badgers, Dachshunds were also commonly used for rabbit and fox hunting, for locating wounded deer, and in packs were known to hunt game as large as wild boar.
Dominant colors and patterns include Red and Black & Tan. Older traditional patterns such as piebald and sable are recently gaining in popularity. Recently, other color and pattern combinations have been developed; it is not uncommon to see Dachshunds with Brown & Tan, Chocolate & Tan, dapple, double dapple, and even white coats. Unfortunately, some of these colors require extensive inbreeding to obtain; double dapples are often born eyeless or with severely underdeveloped eyes. For this reason, the double dapple coat is extremely disfavored among responsible breeders and owners.
According to kennel club standards, the Miniature variety differs from the full-size only by size and weight.
Dachshunds have traditionally been viewed as a symbol of Germany, despite their pan-European heritage. During World War I the animals fell so far out of favor in England and the United States that dachshunds were stoned to death on the street [3]. Many Americans began referring to Dachshunds as "liberty pups", and political cartoonists commonly used the image of the Dachshund to ridicule Germany. The stigma of the association was revived to a much reduced extent during World War II, and it quickly faded away following the war's end. German Field Marshal Erwin Rommel was also known for keeping Dachshunds.
The Dachshund for this association with Germany was chosen to be the first official mascot for 1972 Summer Olympics with the name "Waldi"
One of the odder controversies that has recently arisen in North America is the presence of Dachshund racing events.
This sport originated in a 1993 Miller Lite television commercial that listed odd possibilities for sports (including luge bowling), and has grown immensely in popularity since. It was featured in a half-time show for the San Francisco 49ers. You can see the commercial at the "Wiener Takes All" homepage (see external links below).
While some compare the sport to that of English and later American Greyhound racing, others see it having the possibility of harming the breed from strain placed on its spinal column. Others also see the possibility for abuse of racing Dachshunds, as evidenced by the large number of Greyhounds put to sleep every year once they have proven unsuitable for racing, and by those given up for adoption.

The English Cocker Spaniel is a breed of dog. It is one of several varieties of spaniel and somewhat resembles its American cousin, the American Cocker Spaniel, although it's closer to the working-dog form of the Field Spaniel and the Springer Spaniel. Outside the US, the breed is usually known simply as the Cocker Spaniel, as is the American Cocker Spaniel within the US. Due to the breed's happy disposition and continuously wagging tail, it has been given the nickname "merry cocker".
The Cocker is a sturdy, compact, well-balanced dog. It has a characteristic expression showing intelligence and alertness. Its eyes should be dark and its lobular ears should reach the tip of the nose when pulled forward. The breed's slightly loose skin and feathered coat allow it to fight through any brush unharmed. The Cocker's tail is customarily docked in North America.
Height at withers:
Weight:
Show dogs are restricted to certain colours dependent on country, whereas working Cockers can be any of a wide variety of colours. They come in solid (or self) colours, where white is restricted to only the chest in show dogs, parti-colour, roan, and merle.
Cockers are renowned for their friendly, faithful, playful, and affectionate natures. They are easily trained and make a good medium-sized family pet. Very few Cockers have temperament problems; in a 2002 survey consisting of 487 cockers, only 1% of the dogs were aggressive to people and 2% were aggressive to other dogs [1].
The Cocker is generally a healthy breed. Its main health problems are progressive retinal atrophy, kidney disease, and hip dysplasia. They are also often prone to ear infections because of their pendulous ears.
They live for approximately 13 to 14 years on average.
In the 1800s, small spaniels were developed to help flush and retrieve game. The best hunters were used for breeding. This created the most efficient puppies for the next generation, but the outcome of these hunters was not very consistent, so a split was made. Essentially only the sizes of the pups counted and The Kennel Club divided the dogs by weight alone. If a dog weighed under 25 lbs, it was classed as a Cocker Spaniel (as its primary use was to hunt woodcock). If it weighed over 25 lbs, it was a Springer Spaniel (which was used to "spring" game).
When showing, the new Springer and Cocker, both were in the same class until The Spaniel Club, which was formed in 1885, created breed standards for each of the types. The Kennel Club separated the two types eight years later. Since then, the Springer and Cocker enthusiasts have bred in the separate traits that they desired. Today, the breed differ in more ways than weight alone.
In America, the American Cocker type was forming. As a result, the English Cocker lost favor. The two Cocker Spaniels were shown together until 1936, when the English Cocker received status as a separate breed. The American Kennel Club granted a separate breed designation for the English Cocker Spaniel in 1946.
This breed, like many others with origins as working dogs, has genetic lines that focus on working-dog skills and other lines that focus on ensuring that the dog's appearance conforms to the breed standard, these are the "show" and "working" strains.
After World War II, the show-bred Cocker Spaniel increased enormously in popular appeal and, for a period of time, was the most numerous Kennel Club registered breed. This popularity increased the view that all the spaniels were useless as working dogs. However, for many dogs this is untrue, as even some show bred cockers have retained their working instinct to this day.
Today, this breed is beginning to experience a resurgence in usage as a working dog. Their happy and inquisitive personality makes them ideal service or detection dogs. Dogs from working lines, often refered to as "Field-Bred" cockers are noticably distinct in appearance. As is the case with the English Springer, the working type has been bred exclusively to perform in the field as a hunting companion. Their coat is shorter and ears less pendulous than the Show-Bred type. Although registered as the same breed, the two strains have diverged significanlty enough that they are rarely crossed.
Working-dog lines often have physical characteristics that would prevent them from winning in the show ring, such as heads that are more domed than desired or other traits. This most likely is a result of the crossbreeding of other breeds into the working lines to enhance the working skills for much longer than occurred with the show lines. Eventually, kennel club rules prohibited the crossbreeding of other breeds, and working-line Cockers today show less variation than in the past.

The Field Spaniel is a medium-sized breed of dog. It is one of several spaniel breeds, which serve as gundogs.
The Field Spaniel measures 17 to 18 inches at the withers. Its coat comes in solid liver, solid black, golden liver, liver and tan, black and tan, or roan.
This distinct breed was developed from earlier spaniel breeds as a hunting companion.

Dog Equipment
A muzzled German Shepherd.
A muzzle is a device that is placed over the snout of an animal to keep it from biting or otherwise opening its mouth.
Muzzles are sometimes used on untrained dogs, large or small, to prevent either unwanted biting or unwanted barking. They can also be used on aggressive dogs or other animals. They are usually made with a strong buckle or other fastening device to ensure that they do not come off accidentally.
Muzzles can be primarily solid, with air holes to allow the animal to breathe, or formed from a set of straps that provides better air circulation and allow the animal to drink. Leather, wire, plastic, and nylon are common materials for muzzles. The shape and construction of the muzzle might differ depending on whether the intent is to prevent an animal from biting or from eating, for example.
Dog muzzles can be found in most pet supply stores.

In a dog show, judges familiar with specific dog breeds evaluate individual dogs for how well they conform to published breed standards, hence the more accurate term is conformation show (or, sometimes, breed show).
"Dog show" is often used by the general public to refer to any event involving dogs, such as dog sports, but in the dog world it more specifically refers to conformation competitions.
Handlers set up their dogs for judging so that their stance is perfect when the judge views them.
There are several types of show in the UK. The smallest are the Companion Shows, where there are usually a few conformation classes for pedigree dogs, and several "novelty" classes, such as waggiest tail and handsomest dog, which are open to any dog including crossbreeds. These shows are usually held to support a charity or other good cause.
Then there are Open shows, which are open only to dogs registered with the Kennel Club. There are many Open Shows that are held all around the country. Here the dog & handler can gain experience and the dog can gain points towards a Junior Warrant award or a Show Certificate of Merit.
There are also Limited shows, which are open only to members of the Society or Club running the show, and Challenge Certificate winners (see below) cannot enter.
Finally, there are the huge Championship shows, where dogs can gain points towards a Junior Warrant and compete for the highly coveted Challenge Certificate (CC). If the breed is sufficiently numerous, the Kennel Club awards a Challenge Certificate for the Best Dog and Best Bitch. A dog needs three CCs from three different judges to be awarded the title of Champion one of which must be awarded when the dog is over 12 month old. The most prestigious Championship show is Crufts, and each dog entered at Crufts has had to qualify by certain wins at Championship or Open show level.
A dog who has earned the Championship title is entitled to use the designation "Champion" (or "Ch") in front of his name, for example, Ch. Emerald's Brightest Sparkle.
Show dogs have a registered name, that is, the name under which they are registered as a purebred with the appropriate kennel club, and a call name, which is how their owners talk to them.
The registered name often refers directly or indirectly to the kennel where the dog was bred; kennel clubs often require that the breeder's kennel prefix form the first part of the dog's registered name.
Dog shows take place all year in various locations. Some are small, local shows, while others draw competitors from all around the country or the world. Some shows are so large that they limit entries only to dogs who have already earned their Championships. Therefore, winning Best in Breed or Best in Show can elevate a dog's, a breeder's, or a kennel's reputation to the top of the list overnight. This greatly increases the value of puppies bred from this dog or at the dog's kennel of origin.
Probably the two best-known, largest, and most prestigious annual dog shows are the Westminster Kennel Club Dog Show and Crufts.
The control of points awarded to dogs in most countries is maintained by a national pedigree registry in that country. The Kennel Club of Great Britain is generally recognized as one of the first organizations, if not the first, to register purebred dogs. A second historic registry is the American Kennel Club. France, Italy, and other countries began to maintain important kennel club registries in the 19th century.
Establishing and maintaining a separate breed of dog and, therefore, separate breeding stock and separate registries, from the 14th to 21st century, was not always only a matter of looks or fashion. Dogs have been man's partner for thousands of years. Centuries ago, owners required certain skills and behaviors of some dogs, and many breeds that are recognized today reflect the different jobs that owners historically required dogs to do. A man living in the desert might have needed a dog that could run in sand and last a few days without water or food--that would probably mean a dog with large paws, like a camel, and a very sparse coat to deal with the heat. A man living in polar regions might need a dog that could swim icy waters, run in ice and snow, and survive that region, which would likely mean a lot of coat and a sturdier frame to survive swimming and plodding through snow.
Today, there are dogs who will search the ruins of a bombed building or an avalanche in an effort to find survivors; others assist the blind or the disabled; still others serve as a first defense line to sniff out bombs or drugs. These dogs can do these jobs because they preserve traits historically required of dogs for performing their jobs. A dog standard is a blueprint that describes the physical attributes that a dog breed must have to do its job.

Dog-show judges attempt to identify dogs who epitomize the published standards for each breed. This can be challenging, because some judgements must necessarily be subjective. For example, what exactly entails a "full coat" or a "cheerful attitude", which are descriptions that could be found in the breed specifications.
Strictly speaking, a dog show is not exactly a comparison of one dog to another, it is a comparison of each dog to a judge's concept of the ideal specimen as dictated by the breed standard, containing the attributes of a given breed and a list of conformation points. Based on this, one dog is placed ahead of another. All-breed judges must therefore have a vast amount of knowledge, and the ability (or inability) of humans to retain all these details mentally for hundreds of breeds (and to maintain their objectivity despite their personal preferences) is the subject of intense debate, particularly from the fanciers of working dogs. Politics in the purebred dog world can be as vicious as in any other arena; there have been charges of favoritism, nepotism, bribery and even drugging of competitors' animals.
The judge is supposed to remain free from bias on several counts. A canine judge must, for example, disregard personal or public notions about what a cute or good-looking dog is, and judge strictly to the standard. Judges must also assess specimens of all breeds objective, regardless of personal favourites. In some breeds, the males and females of the breed have decidedly different appearances, and it is often the males who have the quintessential look of the breed. The judge must set personal preference asided and decide objectively whether the bitch is a better example of the female of the breed than the dog is an example of the male.
Winning at dog shows differs in many countries. Dogs shown in the United States, for example, have different championship requirements than those in other countries.
Dogs compete at dog shows to earn points towards the title of Champion. Each time a dog wins at some level of a show, it earns points towards the championship. The number of points varies depending on what level within a show the win occurs, how many dogs are competing, and whether the show is a major (larger shows) or minor (smaller shows).
Dogs compete in a hierarchical fashion at each show, where winners at lower levels are gradually combined to narrow the winners until the final round, where Best in Show is chosen.
At the lowest level, dogs are divided by breed. Each breed is divided into classes based on sex and age. Dogs (males) are judged first, in their age classes. Within one breed, there are puppies (dogs under a certain age), mature male dogs (subdivided by age into junior, limit (or intermediate) and open); bitches (female dogs) have corresponding classes.
The winners of all classes in each sex (called Puppy Dog, Limit Dog etc.) compete for Challenge (best) Dog and Challenge Bitch; the individuals who will challenge each other for the accolade Best of Breed. The remaining class winners are joined by the runner-up from the class from which the challenge winner was selected and there are competitions for second place in each gender, called Reserve Challenge Dog and Reserve Challenge Bitch. This is for fairness, as one class may contain a stronger field of specimens of the breed. If the judge believes that this is the case, the Challenge Dog and Reserve Challenge Dog, for example, may both be from the same class.
From the two finalists (Challenge Dog and Challenge Bitch) is selected Best of Breed. The runner-up is deemed Best of Opposite Sex (or Runner-up to Best of Breed). There is then a run-off in which the second best individual in the gender of the winner (the Reserve Challenge) is brought back to stand against the Best of Opposite Sex (the Challenge who did not win) for the title of Reserve Best of Breed. So, if the Best of Breed is the Challenge Bitch, the Reserve Best of Breed may be the Challenge Dog or the Reserve Challenge Bitch.
In multi-breed and all-breed shows, the winners of all breeds within the kennel club's breed groupings then compete. So, for example, all the Terrier Group breed winners compete to determine Best Terrier (sometimes called Best in Group). These are known as the General Specials.
The audience at a dog show is expected to be participatory and vocal, and often applaud the silkiest, fluffiest or more popular breeds while ignorant of the breed requirements. Those who are owners and breeders may cheer for a popular handler or a sympathetic favourite from a particular breeding kennel; the judge is supposed to ignore all attempts to influence the decision.
Finally, the winners from each group compete for Best in Show.

Dog law
An animal control officer (also, more informally: dog catcher or dog warden or ) is an employee of, or a contractor to, a municipality, charged with catching stray or loose dogs, cats, and sometimes other animals, and bringing them to a compound or animal shelter, where the animals are held for a certain time before being returned to their owners, put up for adoption, or euthanized. Animal control departments are also responsible for investigating incidents of human contact with both wild and domestic animals, such as bites. They usually work with Health Departments to ensure the health of humans injured by animals.
Variations of the historical phrase "I wouldn't vote for him for dogcatcher" or "He couldn't run for dogcatcher in this county" refers to an individual so poorly regarded that the individual in question is not fit to be elected to even a trivial position of public trust. In actuality, this position is usually an appointed one in localities that have a dedicated full-time animal control officer.

Dog organizations

A kennel club (known as a kennel council or canine council in some countries) is an organization for canine affairs that concerns itself with the welfare, promotion, and maintenance of more than one breed of dog. A club that handles only one breed is known as a breed club. All-encompassing kennel clubs are also referred to as 'all-breed clubs', although "all" means only those breeds that they have decided to recognize, and "breed" means purebred dogs, not including dog hybrids and crossbreeds or mixed breeds.
Kennel clubs can be for working dogs or show dogs. They maintain breed standards, accreditation of judges, and registries, which are lists of adult purebred dogs and lists of litters of puppies born to purebred parents.
Nations that have active groups of dog breeders and people who practice the hobby of dog fancy usually have their own national breed and kennel clubs, often affiliated with those of other countries.
The Fédération Cynologique Internationale (In English, the International Canine Federation, but still referred to as the FCI); represents many countries internationally and has ties to many countries' major kennel clubs. There may be reciprocal agreements or understanding between affiliate members of the FCI.
The major, most-widely accepted kennel clubs for various countries are:

There is much discussion about what exactly defines a sport for dogs. Some issues:
This list is intended only to represent anything that anyone is likely to refer to as a dog sport, not to argue its validity as sport. Clearly, there are more sports to add to this list:

Dog training is the process of teaching a dog to exhibit certain desired behaviors in specific circumstances. Some examples are:
The specific behaviors taught in each case are different, but the underlying principles are similar.
In the wild as pack animals, canines have natural instincts that favor training. These instincts are manifested when the dog lives with humans as a desire to please a handler, as a dog would please senior members in a pack in the wild. The handler is simply whoever is working with a dog at the time.

Dog types
Bulldog is a collective name for various breeds of dog.
The bloodsport of baiting animals has occurred since antiquity, most famously in the Roman Colosseum; however, in later centuries, it is most associated with the English, who pursued it with utmost earnestness, which was barely known elsewhere in the world. For over six hundred years the pastime flourished, reaching the peak of its popularity during the sixteenth century. The various animal types involved in the bait resulted in the breed specialization and basic anatomical forms of fighting dogs, which we still see today.
The first historical traces of bull-baiting occur in the time of the regency of King John. Enraged steers, specially bred for their aggressive nature, were used to test the keenness of dogs. A collar around the bull's neck was fastened to a thick rope about three to five metres long, attached to a hook, then fastened to an embedded stake that turned, allowing the bull to watch its antagonizer.
The dog's goal in the attack was to pin and mercilessly hold onto the bull's nose, which is its most sensitive spot. If the dog gripped tightly, the bull became virtually helpless. To avoid this attack, experienced fighting bulls lowered their heads as much as possible in the direction of the attacking dog, protecting their noses and meeting the attacker with only their horns, tossing the dog into the air. The dog reciprocated by staying low to the ground as it crept towards the bull. These tactics resulted in a specialized breed in the form of the now-extinct original Old English Bulldog. This breed was extremely compact, broad, and muscular. A particular characteristic of the breed was the lower jaw that projected considerably in front of the upper jaw, which made possible the strong, vice-like grip. The nose was deeply set, which allowed the dog to get enough air as it gripped the bull. The contemporary recreation of the breed is called the Olde Englishe Bulldogge.
The English Bulldog of today is a far cry from its ancestor, which made its name by excelling in arranged combat. This breed of bulldog may be a fine animal to own for its sweet disposition, but it has maintained nothing of the tenacity, speed, and agility that were the definitive characteristics of the Old English Bulldog.

Dog-Related Professions and Professionals
A dog-show judge is a person that is qualified to judge dogs at a dog show. Depending upon the size of the show, there might be one judge for all breeds and classes. At larger dog shows, there might be as many as 10 judges working.
Usually a license as a Dog Judge is granted by either a Breed Association or a Kennel Club. The license might either show the range of breeds that he or she is able to judge, or otherwise any exclusions. Judges may study for a license to judge a dog group: (She is a terrier judge). A judge who has successfully completed the requirements for judging all of the dog groups is known as an all-breeds judge.
Historically, the dog judges of the English-speaking world had 'circuits' if they travelled out of their own country. They would carry their license from their country of origin, and usually would be recognised overseas.
Some judges who are regulars at the larger English or American dog shows become well-known and gain respect from large audiences for their ability to recognise good examples of the breeds that they judge.

Dogs as pets

Animal shelters, or what used to be known as pounds or dog pounds, are either governmental or private organizations that provide temporary homes for stray, surrendered, or abandoned pet animals. They most often house dogs and cats. The animal is kept at the shelter until it is reclaimed by the owner, adopted to a new owner, placed with another organization, or euthanized.
Unfortunately, resources are seldom adequate to support the large number of animals taken in by these organizations. As a result, animals that are not claimed by their owners, or that have temperament or health issues that cannot be corrected or treated within the resources of the organization, are often euthanized. Shelters that receive a disproportionate number of animals compared to available adopters may also euthanize animals because of space concerns.
A small number of shelters have chosen to be "no-kill" shelters, which support healthy and adoptable pets for the remainder of their lives or until they are adopted. However, as funding is limited, the number of animals that can be accepted by these organizations can be low, and some animals may not be accepted because of behavior or health concerns. "No-kill" shelters often do euthanize if they receive animals with these problems. There are no clear standards for assessing these issues, and so statistics cited about how many "adoptable" animals are euthanized or adopted can be meaningless. A poorly managed no-kill shelter may accept more animals than can be properly cared for and maintain animals in crowded and unsanitary conditions in much the same way as an animal hoarder.
Some people obtain their pets from pet stores. Millions of these pets are taken to shelters or abandoned when they get sick or are no longer wanted. Animal Welfare groups and volunteers are attempting to change that point of view by educating owners and potential owners about the lifelong commitment involved in adopting an animal, how to be a responsible pet owner, about the large number of adoptable animals available at shelters, and about the often poor condition of pet shop pets.
Animal control agencies, or nonprofit organizations contracting for animal control duties, also enforce animal-related ordinances. Some animal shelters also provide low-cost spaying and neutering surgeries or veterinary care, behavior training or resources, "safe havens" for animals of abused spouses, or other services.
By contrast animal sanctuaries will look after animals for the rest of their natural life, without necessarily attempting to find them any other home. Some establishments combine the qualities of an animal shelter with those of a sanctuary.
An animal shelter can be started by anyone who has the commitment, time and desire to help homeless animals. There are many resources available to assist in establishing an animal shelter, sanctuary or animal foster home. If an organization chooses to qualify for 501(c)(3) non-profit status, there are certain criteria outlined by the Internal Revenue Service (United States) which must be met. Additionally, running a non-profit animal shelter requires good business practices and skills. The best method of determining if one has the capability to run an animal shelter is to volunteer their time at a local Humane Society or shelter facility. These organizations can be found through local yellow pages or a search on the Internet using your state or city name followed by "humane society" or "animal shelter".

This working dog is a border collie mix.
A working dog refers to a canine working animal, i.e. a dog that is not merely a pet but learns and performs tasks to assist and/or entertain its human companions, or a breed of such origin.
Arguably the variety of -often exclusive- canine jobs is a better justification for the dog's honorary title "man's best friend" than the more accidental popularity as pet number one in western cultures.
Within this general description, however, there are several ways in which the phrase is used.
Several cities in Italy are experimenting with working dogs as rescue swimmers. In this situation, a strong and well-trained dog is equipped with flotation devices and dropped in the water near a floundering swimmer. The swimmer then grabs onto the dog, and the animal tows the swimmer to shore. The Newfoundland has long been used for water rescue, not only on shore, but from fishing boats as well.
Dogs are commonly used as search and rescue workers in cases of lost persons and disasters. The St. Bernard was historically used in Europe in the case of avalanches and lost travelers. Rescue dogs in the US are used in thousands of lost person searches each year saving countless human lives. In the aftermath of the 9-11 attacks in New York, rescue dogs searched the rubble pile for survivors. When searching such large disaster sites some dogs become so disturbed at being unable to find any survivors that people are "planted" for the dogs to find so that the dogs retain their enthusiasm and work ethic.
