OFA is not reliable when trying to decide which breeds have HD more than others. I know if my dog got her X-rays done and the vet determined they would most likely come back OFA Dysplastic, I sure as heck wouldn't pay the money to send them in. The reason 99.9% of OFA x-rays that don't come back with numbers say the dog is only dysplatic in one hip is NOT just because hip dysplasia in one hip is more common -- it's because OFA looks at the hip joints TOGETHER rather than seperatly and grades them as such. If the other hip is truly in excellent shape, perhaps your grade as a whole may be better. Pennhipp is a better source for information as the vets must send the results in -- it is illegal if they don't. If you check with Pennhipp or ask your vet, I can guarantee you that the GSD is in the top 5 for hip dysplasia. We don't get alot of GSDs at the shop, and I'd say that GSDs make up the majority of dysplastic dogs we get.Originally Posted by jackfrost
I will also guarantee you that because there are less American white shepherd breeders than German shepherd breeders, and the American white shepherd breed was started in the day and age when we were more informed about health and temperament issues, that German shepherds are more likely to be dysplastic. More breeders, more health problems. White shepherds are also easier to show than GSDs -- if you look at pictures of many of them, they have ear placements and such that would never be acceptable in the GSD ring. Good reason to breed more for health and temperament, less for show. Belgians are the same way. Very easy breed to show as long as you have the temperament. Less of them, less to compete against.
It seems silly to me that people think just because they are breeding colours together, there is a limited gene pool. What if people were breeding black to black? Would there be a limited gene pool then? Of course not. If I bred strictly groenendael to groenendael, would I have a limited gene pool? No...And I'll bet you that there are more white GSDs registered with AKC and CKC than there are groenendael. Lines are one thing -- certain lines can be hard to get away from. But dogs in certain lines aren't always related, nor do lines always stay the same.
