Walter had his surgery last week and now 10 days later has started favoring his back right leg once in awhile now. It seems to come and go at odd times but we can really tell after a long nap or if he plays a lot. He doesn't whine or whimper at all, just limps. We are planning on bringing him back into the vet Monday morning to have them check him out but thought I would check with you guys one here too. Thanks for any help.
