  • Patent number: 4483275
    Abstract: A training halter is provided for animals having muzzles, such as dogs, which in essence replaces the collar and leash and which diverts the tugging force to a self-cinching strap looped around the muzzle, so that the trainer, rather than merely pulling against the mass of the animal, can turn its head in the direction to which he wishes the animal to move.
