I just started Duke on that medicine that Glacier was talking about. Doubling up on Rimadyl wasn't helping at all. Today was only his second day and the vet said I probably wouldn't see anything noticable for about a month but I think it's working better already. When I got home today, Duke wanted me to play. So, hopefully by three weeks, he'll be in a much better frame of mind for the PT get together. That and the other things we've discussed should help immensely.
