I have a litter of pups on the ground and have done all the clearances (hips, elbows, eyes, thyroid, and CNM). For the Hip’s I use a local vet and send them to OFA. I had a perspective puppy buyer all but call me a fool for using OFA rather than Penn Hip. His logic was that he had a “good OFA” that scored poorly on the Penn Hip system so the Penn hip is better. I’m trying to be open minded but that’s not making much sense with me. Please answer the survey and give your reasons why you prefer one or the other. Thanks in advance.
