  • Patent number: 5732660
    Abstract: A combination collar and leash with built-in muzzle loop for use as a humane approach to controlling, restraining and achieving obedient behavior of animals, especially dogs. An adjustable collar loop encircles the neck of the animal at a comfortable position on the animal. A leash attaches to a ring secured to the collar. Built into the leash is a fully adjustable muzzle encircling loop. The muzzle encircling loop can be readily loosened or tightened, shortened or lengthened to accommodate different sizes and types of muzzles without interfering with the integrity and functioning of the leash. The muzzle encircling loop passes through a ring attached to the collar to form a control device which can be tightened down into a muzzle or left in a loosened position to be used as a humane control or restraining device to aid in achieving obedient or desired behavior.
