My lab may have injured his ACL while pheasant hunting a couple of weeks ago. I took him to the vet and after examining him and doing the drawer test he thinks it could be a partially torn ACL. Anybody have any experience with these especially with Labs? He is not in pain and it only is noticeable after he is lying around and gets up quickly. I am really hesitant about surgery because trying to keep him still for 3 weeks and then limited exercise for another 6 is going to be tough. It is a shame since he was really having a very good year with pheasants and grouse. He is a 4 yr old nutered male and is really turning out to be a very good bird dog.
