I took Scooter to the doctor. Of course he was a wild man when I got there, so she couldn't see him limp. When she examined him she thought perhaps he could have a strain in his left shoulder. We have some anti-inflammatory medication to give him, and we will see if it isn't better soon. It could also just be a little arthritis. Yes, I know what that is like. I either have to sit or walk, but standing still absolutely kills me.
