Laurel Saint James, NY 5/4/2009 7:01:31 AM In reponse to the "responsible bredder" knowing a pup might have dysplasia, I take exception. I'm not a bredder, but have had several labs in my life. I have OFA certs form all the parents of my pups and yes I have had a dog who had dysplasia. OFA certification can help with the odds, but is NOT a guarantee. Purebreed dogs always have defects that run in every bred, and chances of having problems. If you want to increase your chances of genetic problems, get and "American Mix" also called a mutt.
