The personality of a dog is flexible and indeterminate. Dogs can be exuberant or shy; friendly or hostile; fearful or bold; aggressive or passive or some combination of the above. These differences in personality may to some extent be determined by breed, or individual genetics, but for the most part it is based on how and to what extent each particular dog has been socialized.
Everyone is familiar with sit, down, and come and other similar commands that are standard fare in the general obedience training class. The novice handler might not be familiar with what competitive obedience looks like or realize that it’s really just a continuation of those basic skills.
Before a dog is ever entered for a competitive show, there is a lot of work that must be accomplished in order to be able to present the dog properly. There is nothing like having a quality dog that is unprepared for a show. A dog that hasn’t been well trained and conditioned just won’t be a competitive dog.
