I was just wondering how your dog was doing. I've had quite a bit of experience with this disease, as our dog has had this condition for over 3 years. I can tell you, that it is difficult, but possible, to deal with. Our 100 lb. yellow lab/greyhound mix can only open his mouth about 1 inch. Even under anesthesia, his mouth cannot be opened any further, although it was still possible to intubate him. Once the muscles in the head & jaw deteriorate, they cannot come back. It's not just a matter of strengthening muscles already there, which is important, but once the muscle tissue is gone, it can't be created. Many specialists, many thousands of $ later, and the treatment consists of prednisone, that we adjust as low as possible according to his condition (which does change a little bit, both for the better and the worse, but never very much to result in much greater ability beyond an inch or so), and feeding food that he can tolerate (mostly wet food) and treats that are intended for very small dogs.
