I would like to touch briefly on a common tool that I personally have had great success with over the past few years when used correctly, it is the gentle leader. This is not a muzzle in anyway shape of form this is simply a tool to help teach your dog to walk in a proper heeled position with practice. If you are interested in purchasing one, click here. When getting your new gentle leader simply follow the directions supplied in the box and you will be on your way to a pleasant walk.
