I can't speak on any breeder on your list , I don't know them or their dogs . I don't think there are breeders breeding dogs with problems for conformation competitions , I know it , and i know folks who have sold them the dogs knowing the dogs problems , it's not an opinion .........I've seen champion dogs , gr. champion dogs you couldn't pay me to take , I've put my hands on them , knew their pedigrees better than the folks showing and breeding them ....I wouldn't even begin to think a dog show judge could tell me if I had a good dog by looking at him/her for a couple minutes , the thought is ludicrous .. I've seen dogs used regardless of their health because of their pedigrees ....... I've seen "world class" dogs limp to a win on a "world class" stage ........ I've seen folks pay a professional handler to champion their dog that was far from "world class" . then use the dog for the "betterment of the breed" ....... health certs ? I've seen puppymills use them to market their unhealthy junk dogs ......... I don't believe all breeders are incompetent , or all incompetent breeders are breeding for money , I think many don't have a clue what a good dog is , and many just want to win for their ego's ..... a champion dog and a good dog have nothing to do with each other ......seeing a 6 generation pedigree is meaningless unless you know the dogs ........I know some very famous dogs that were linebred on that are responsible for a lot of genetic problems that plague some breeds i'm aware of ........ I don't have a breeder , my dogues are mine ..... as far as melkev's you'll have to ask her , I didn't buy my simon because of his parents health certs , I bought him because of his parents , and the folks that bred him were dog people ..... I wanted to breed to his father , it didn't work out , so I got pick pup in the breeding of two int. ch. dogs , both ROM dogs , that's an accomplishment for a bitch , both fully adult healthy dogs when bred , not 2 yr old puppies , I believe both lived to 10-11yrs ....... the best health cert a dog could possibly have is longevity , and overall health during that longevity ....... I agree there is a big difference between a breeder who cares about the pups they produce and the ones producing pups to make money ...... the problem is the best way to make money on pups is marketing with titles and health certs , even the puppymillers know that
