Yes, I do plan on taking him to the vet, I guess I just fell kind of dumb telling him "oh, I don't know what's wrong, he just acts weird." But yes, he also does whine sometimes when he gets up, but I think it's his right leg. He hurt it a while back, and whenever he plays really hard, or does alot of running, with our neighbors schnauzers (along the fence) he is really sore the next day, & I usually give him an asprin & he feels better. I'm kinda thinking that he might have arthritis in it. Would a vet be able to tell something like that?
