We have a 4 year old Black Lab mix we rescued from the humane society as a puppy. We recently have become interested in Pheasant hunting and were thinking about training him to be our pheasant dog. He loves to chase and tree squirrels in the backyard, in fact the minute we say the word squirrel he runs to the back door and runs right outside and he finds the squirrel and trees it.

We took him with us dove hunting one time to get him use to the sound of the gun. He was scared for the first 20 or so shots but seemed to get over it. Is it possible to still train him to be a pheasant dog at the age of 4? We don't have the money to buy a pure breed puppy or support another dog so thats out of the question.
