So glad he is out of surgery. He'll probably need to be kept quiet for awhile, but you'll get through that knowing each day he is healing a little more. My Rickie had partial joint fusion surgery and it was a long road back. Now, while I let him run around in play, I am fairly conservative lest he re-injure. We do very long leash walks too.
Your immediate challenge will be keeping the bandage dry. I'll look for Boomermom's thread on this with her foster Foxy, as it has some good ideas - here's the link:
