I have a question, and this has always confused me. Fiona my 2 year old yorkie started limping sometime around last May, I took her to the vet and we were concerned that she has lost muscle mass in her right leg. They took Xrays and they were suspicious of Legg Perth Disease. The Xrays were sent to a specialists at Ohio State University, and they confirmed Legg Perth Disease. I spoke with the vet on my options. She could have the surgery. Now by the time all of this information was brought back to me she was no longer limping. She had been put on pain medication which seemed to do the trick. Because she stopped limping and now runs and walks on her leg like a champ, and no long as a decrease in muscle mass in that right leg, I kind of forgot about the whole thing. Is there something that I am missing? I spoke with the breeder, and she told me that she has never heard of Legg Perth Disease and has been breeding yorkies for years and years. She has 2 of Fiona's siblings and her mother, and keeps in touch with most of the people who get her puppies. So I am wondering, if she is not having any difficulties with that leg, should I be concerned, and maybe consider the surgery?
