I think Blitz may have torn his ACL a couple days ago. He won't jump up on the bed and has yelped on the rare occasion he did jump. It didn't happen doing any hunting. I think he was just out in the backyard when it happen. I tried to find a spot that may be causeing the pain but I can't find anything. Does anybody have any experience with this? I'm going to try and get him to the vet on Monday and see what's going on. Thanks for any insight on this.
