Hi Lynn, I'm going to assume you went to see your regular veterinarian who may not be a board certified orthopedic specialist? I would urge you to seek the opinion of such to put your mind at rest. I had one of my puppies come up lame and the regular vet filled the owner's head with a variety of possibilities and I immediately got them an appointment with our local bone guru and I went with them to the consultation. He reviewed their xrays, booked him in for some new xrays to compare and completely ruled out the speculative diagnosis of the regular vet, our puppy's joints were all good but he was experiencing bone pain which will be self-limiting. I'm not saying that regular vets are always wrong but each to their own field of expertise. Go see a board-certified orthopedic specialist:-)
Talk to your breeder and ask if there is a history of panosteitis or bone pain in her lines and if any other littermates have reported problems. With my puppy there was a family history behind the stud dog I'd used but the effect was short-term with no further problems. All the best Rose T.
