I see dog and horse shows (and some other large animal shows) as completely different.
A GP having spots, stripes or curly hair doesn't make it any more special then a plain old GP.
A dog's ability to herd, lead the blind, retrieve, rescue, etc...are useful skills that the dogs usually enjoy doing. I prefer "function shows" over beauty shows but most dogs seem to enjoy both. An unhappy dog will not show well. Thus will not win. I have known show owners and these dogs have fabulous lives.
I feel the same about horse shows, prefering function over beauty. I love to see a well matched horse and rider perform dressage, jumping, cross country. It's teamwork. A horse that does not trust and respect it's rider will not perform well.
I do wish they would make the overuse of crops a fault though. I hate to see Thoroughbreds and Standardbreds being smacked with those crops. I understand the "grazing encouragement" of the crop, that doesn't hurt. But those riders that are using all their strength to beat on the horse with a crop....Give me 5 minutes with them and that crop and they won't be so eager to use it as much.
