I don't know how your dog would react to a prong collar but in most classes pullers wear them and even a child could walk them. They instinctively know when they have it on and come to a perfect heel. After some time the dog will heel with just a plain nylon or leather collar. No pulling or yanking involved, the collar does the work. You might ask a proffessional trainer to show you how to use it if you're unsure. They're only inhumane if a handler pulls or jerks the dog hard while it has the collar on. Best way for the dog to learn to heel properly with it on is to change direction frequently making him keep an eye on you.
