Oh boy, please don't let him jump or run or wrestle or anything. He should really be contained for the recovery time. He could very easily re-injure and it could not be set right and start to heal wrong, and then you might be forced to do surgery.
My Roxy has had knee surgery 2 x already. The recovery period was at least 8 weeks and during that time, she HAD to be contained and limited use of her legs. |
