Apparently you haven't had much personal contact with breeders and exhibitors.  My dog, an AKC and UKC champion, with multiple obedience and rally titles, is currently snoozing on the couch beside my desk.  He slept on the bed with me last night, as he does most nights.  I put more effort, time, and money into his care, nutrition, and health than I do my own most days.  I love competing with my dog, as do the vast majority of the exhibitors and breeders that I know.  His breeder has been in dogs for over 30 years.  She health tests all of her breeding dogs, and by health testing, I mean echocardiograms administered by board certified cardiologists, thyroid testing, hip and elbow x-rays, eye exams administered by board certified opthamologists.  She also competes with her dogs in performance events as well, like obedience and agility.  

Are there some 'bad apples' in the bunch?  Yes, just as there are in most anything humans are involved in.  But don't paint us all with the same brush.
