I have done the prelims at 5 mo for 20 yrs on puppies I have wanted to keep for the breeding program. I have been lucky to pass these x-rays on pups keeping. At 2 yrs all have passed the OFA & I am into my 5th generation. I have kept one hoping to get better, but never did at 2. You really have to trust a knowledgable vet to read the x-rays. All the shepherd breeders in St Louis use Dr Bruce Garber. ============================================================================ POST is Copyrighted 2005.
