Is it common for a Breeders vet to come to a different opinion about Hip dysplasia than your vet when there are hip grantees in effect? I had my dogs hips X-Ray at 1 year yesterday and my vet felt they were displaystic. I emailed the same x-ray photos to the breeder and 10 minutes later got a reply that his vet looked at them and said they were not and to get and OFA rating. Is this common that vets disagree about these things? I am going to go ahead and get the OFA rating just to know but I'm curious is this common? I would have thought that with something like that vets would agree in general but maybe not.
