Abstract: An animal harness having a rectangularly shaped slotted plate for resting on the back of the animal rearwardly of its forward shoulders and a single control strap adapted to be attached to a leash and for cooperating with pairs of rings for defining right and left foreleg slip loops. A pair of restraining straps pass through the rings and are coupled to the plate by a latching arrangement, cooperate with the slip loops to form a block and tackle arrangement which utilizes a pulling force exerted by the animal, to exert a restraining force across the upper foreleg muscles of the animal when the leash is held in a substantially stationary position.
