Lilly is a 9month old yorkshire terrier. On friday i noticed that she was picking up her back
leg whilst
running, but when walking she is fine on 4 legs. She puts weight on the leg, sits on it, lies on it, she is still jumping up. When my boyrfriend touches the leg she is fine, when i touch it to see whats wrong she snaps at me. (She is my dog) but only occaisionally, almost like a child who pretends their ill and forgets to say oh that hurt but will do it next time.
