Usage: The Halti works on the same principle as a horse's head collar: guide the head and the body will follow. The halti allows a strong dog to be made to walk to heel without choking or physical force - dogs do not pull against a Halti. A Halti makes walking the dog easier and speeds up training. It can help overcome many behavioral problems. A full instruction book is included. There are 6 sizes:
