Glad to hear he's feeling better... Sounds like your going to have your hands full keeping him quiet...I had he same problem with Nikka after her hip surgery. The vet said keep her quiet and off it for 2 weeks The first couple of days were fine...she had enough drugs in her she was fairly sleepy all the time. But, as soon as those tapered off she was out and running the yard. We put a sock on her foot with a small ping pong ball in it to force her to use only 3 legs when she went out potty (she won't go on a leash... ). She'd always go around the house where I couldn't see her from the deck and come back with the sock off running on all 4's. 2 weeks we battled this, I was so thrilled when the vet gave the all clear to let her use that leg again. I took everything off and let her go....and watched as she hopped around on 3 legs....2 weeks of battle and now that she's given the all clear she won't use it. ....It took me another 2 weeks before I could get her to use that leg.
