Hottie has a plate in his left rear leg also. I had to watch no stairs for a month, and had to keep the doors shut on the bedrooms so he wouldnt try to get on ( or worse ) a bed. I also got a thick orthopedic mat then covered it in a tight fitting sheet and comforter for him to sleep on while he healed.
YOu can give your boss my email address if he needs any help/support/ whatever from me.. I will be more than happy to help him in any way I can.
Also - remind him, borzois are drama queens- they will run at something in the yard crashing over tree branches etc never say a word- while triming toenails makes a yelp in a "KI-YI-YI-YI-" noise. They also learn reallllllllllll quick that if they look at you and yelp out of no where, you will be started and give them something in affection or treats.. lol..
