You will have to train the dog basic obedience. Sit, come, stay, etc. Any dog training book will do at your local library or you can take classes. I would do this before taking him in the field or train him in the field before hunting him.

Next, introduce the gun.You can introduce game also but don't know much concerning fur as I hunt mostly birds.

You can train any dog to retrieve using force fetching. Check out http://www.oakhillkennel.com/library/force/force1.htmland http://www.oakhillkennel.com/library/force/force2.html
