Does he appear to be in pain, is he whimpering? Has he had a bowel movement? Is he eating?
It is good that he is taking it easy. If you need to confine him in a week when he starts to feel a little better and more confident on that leg, do it. Don't let him get at the wound site. Wishing your dog a speeding recovery.
