I'm going to Vet Saturday but want to throw this out there for comment. I have a 18 Mo old YLM. Occasionally when he walks or trots he doesn't put his right rear leg all the way down. Sometimes he just hits the ground lightly with right rear foot other times he only puts it half way to ground and doesn't touch foot to ground. Most of the time he walks/runs normally but I notice this occasionally. I've checked his pad and nothing there so I figured it must be a joint higher up. Sits fine, gets up fine. Any thoughts?
