  • Patent number: 5370083
    Abstract: A leash controllable harness adapted to inhibit a dog wearing the harness from straining against the leash held by an individual walking the dog, the harness inducing the dog to come to a halt or to walk at a pace acceptable to the leash holder. The harness is composed of a pair of loops that depend from a leash-coupling junction at which the loops are joined, the loops being angled at the junction with respect to each other so that they cross over at a crossover site below the junction. When the harness is installed on the dog, the coupling junction to which a leash is connected then overlies the dog's shoulder intermediate the right and left forelegs, and the crossover site lies under the dog's chest, one loop running from the site through the crotch between the chest and the left foreleg and back to the junction, the other loop running from this site through the crotch between the chest and the right foreleg back to the junction.

  • Patent number: 5365881
    Abstract: A handle for a grooming brush that makes it possible for a groomer to grip the handle in a manner effecting optimal control for a selected mode of brushing activity, such as vigorous, down-stroke brushing. The handle has an elongated body whose leading end section is attached to the rear of the brush at an angle thereto. The leading end section of the handle has an upper surface defining a center thumb rest and concave depression on either side defining left and right side thumb rests. The groomer who grips the body of the handle with his fingers may then press his thumb on the center thumb rest to carry out one mode of brushing activity, or press his thumb into one of the side thumb rests to carry out other modes of brushing activity.

  • Patent number: 5359964
    Abstract: A leash-controllable dog harness adapted to inhibit a dog from straining against a leash held by an individual walking the dog, the harness inducing the dog to come to a halt or to walk at a pace acceptable to the leash holder. The harness is composed of a pair of loops and a shoulder junction having left and right openings, each loop being formed by a strap of adjustable length whose leading end is linked to the junction and whose trailing end slides through a respective opening and is coupled to the leash whereby when the leash is strained, both straps are then pulled. The loops are angled with respect to each other to interconnect at a crossover site. When the harness is installed on a dog, the shoulder junction then overlies the dog's shoulder intermediate the right and left forelegs, and the crossover site lies under the dog's chest, one strap running from the site through the right foreleg crotch, the other strap running from the site through the left foreleg crotch.

  • Patent number: 4964369
    Abstract: A dog harness to which a leash is attachable. When installed on the dog, the harness acts to inhibit the dog from straining against the leash without, however, producing a choking action. The harness comprises a collar that encircles the neck of the dog, and left and right restraint cables whose leading ends are connected to the front section of the collar at left and right positions thereon. The restraint lines go loosely under the left and right foreleg pits of the dog and through respective slip rings attached to the rear section of the collar adjacent its center, the trailing ends of the cables terminating in a coupler to which the leash is attached. When, therefore, the harnessed dog strains at the leash, this acts to tighten the restraint cables which then impose a pressure on the foreleg pits. Because these pits are highly sensitive, in order to relieve this pressure, the dog will then cease to strain against the leash and thereby again loosen the restraint cable.
