Directions: Attach leash to control ring Open neck strap and hold each end so the nose loop and lead look like a T. Place on neck with center bar ring just above Adam’s Apple, and adjust so that only one finger will fit between neck and strap. Take neck strap off dog; slide adjustable snap clip down to leash ring. Pull nose loop up through center bar ring. Hold nose loop open and slip onto dog’s muzzle; snap neck strap closure shut.
