Use some deer blood, or any blood you can get and make blood trails in your yard or woods. As your dog gets better, let the trails sit longer and dry up. At the end of each blood trail, use some sort of treat. I use to hide a piece of liver for my dog at the end of each trail and it was serious motivation for the dog. Eventually, she was a tracking machine. A tracking dog can be an awesome tool for finding deer. We have found deer with my dog that there is no way we would have found on our own. good luck.
