Don't forget the so called "sport" of driving a car around a track hundreds of times, all the while trying not to kill yourself. hehe
I agree with you. Conformation showing is not a sport - it's a skill. About the only exercise anybody gets is trottin' 'em round, and while a good handler has the knack of showing a dog to advantage, it requires knowledge not athletic ability.
Agility to me is a bit more towards the sport end, since there IS some athletic ability required on the part of the handler as well as the dog. Not only do you have to run like mad to keep up with a dog off leash, you have to learn various physical maneuvers (front cross, back cross, pivot, etc.) to steer your dog to the correct obstacle. But I wouldn't argue TOO vigorously with somebody who wasn't convinced . . . :-D
