I had Labradors years ago and they were all OFA good or excellent for 4 to 5generations back. Still I would get OFA fair puppies now and then. I had one dog OFA'd and his parents were OFA excellent. He OFA'd fair. I talked to the vet about this and he said that sometimes its the way the dog is positioned on the table when x-rayed and who is reading the x-ray. These factors can determine how the OFA will come out. I had the dog done again and he was OFa good. so OFA readings are not alwasys accurate either. |
