If you are wondering why some of the previous years' top placing dogs can't be found in the current year's top placings, it MAY be because they have been placed in the "T" Category listing at the BOTTOM of their Class!!
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.
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.
