German Shepherd Dog

Dog training is the process of teaching a dog to exhibit certain desired behaviors in specific circumstances. Some examples are:

• Teaching a dog basic obedience commands (part of obedience training)
• Teaching a dog to perform tricks casually or for circus acts
• Teaching a guide dog to lead the blind
• Teaching a rescue dog to find victims of a disaster
• Helping a hunting dog learn to perform its instinctive behaviors at appropriate times

The specific behaviors taught in each case are different, but the underlying principles are similar.

One of the most fascinating aspects of the game of contract bridge is the numerous ways that exist to establish extra tricks.

The card game auction bridge was developed from straight bridge and was a predecessor to contract bridge. Around the same time five hundred was created by the United States Playing Card Company in 1904.
