As I understand it, hip dysplasia, Eye problems, and now CNM are genetic defects. Many people are breeding their registered retriever to the "good hunter down the road" getting good hunting dogs with no regards to potential genetic defects. Now on to my question, If they are in fact genetic, why hasn't an organization like AKC taken a position and not allow the registration of pups/dogs unless they have passed a test. Give a dog a limited registration until they have passed a a CERF exam, received a good or excellent on a hip exam and negative for CNM then offer a full registration. Over a couple of generations, wouldn't this take care of the problem in registered dogs??
