Another book by Paul ans Julie Knutson titled.."The Pointing Labrador"...they state..."Use the level of discipline or correction to stop your dog fromengaging in unacceptable behavior that work's with your dog. Do not use abusive or cruel, but be effective in your correction. Stop poor behavior before it become's a habit. Get professional help if necessary, but do not let poor behavior continue. If you cannot correct a 12 week old pup, you will never handle a mature dog with problems"......Hope some of this help's..
