I came home from the swap this morning to a limping dog. Jake is 10 and has several health problems he has seizures, and narrowing of his L4-L5-L6 in his back. this makes him uncoordinated, he can't seem to feel his feet. he has lost control of his bowels too. He had to retire from therapy dog work. he won't put weight on it and of course it is sunday. does it look broken ?
