Abstract: A harness is disclosed that fits over an animal's head, such as a dog, and buckles around his chest behind the front legs. Straps, independent of the harness, are fitted around the dogs front legs and are attached to the leash through four D-rings (two D-rings attached to each side of the harness). The lower D-rings are located in such a position that the leg straps, when pulled back by the person walking the dog, pull straight back or perpendicular to the dogs legs. As the animal tries to walk faster or pull faster than the person walking the dog walks, the straps around the dog's legs pull back perpendicular to the dog's legs preventing the animal from walking faster than the person walking the dog. The harness is designed to restrict the movement of the dogs front legs by the force of the dogs own pulling power. The more the dog tries to pull, the less movement the dog has in his front legs.
