Susie, I'm so sorry! I've never heard of a small dog having that - it's usually Leggs Perthes. That is really bizarre. So what is the long term picture like? Will she walk ok, run? Will you be doing the PT with her or do you have to bring her in to do it?
Boy, if it isn't one thing, it's another with our pups, isn't it?
You take care of yourself, ok?
