Why and How the Gentle Leader® Headcollar Works
First of all, the Gentle Leader® Headcollar is NOT a muzzle. When fitted properly, your dog is free to open his mouth to eat, drink, pant, fetch, bark and even bite - except when you close his mouth by pulling on the leash.

The Gentle Leader® Headcollar features two soft nylon straps - the collar portion fits high at the top of the neck, and the nose loop fits loosely and comfortably across the base of the muzzle. Each strap has a distinct and important effect.
