Oh my God!!! I think I know what is wrong with your dog!!! We had a black lab that put on new bone growth. Wer spent almost 5,000 trying to figure out what was wrong with him. How much protien does she get a day? Anyway is it alright for me to email you? I have a lot of information that might help. I will call my DH he knows the exact name of this disease, and hopefully I can point you in a new direction, that works. If this is what she has then she will live, even though she may not be able to be as active. Hang tight there.
