PetSafe Sport LeashThe Sport Leash helps you keep a firm grasp on your busy life. The unique hand wrap adjusts to your palm and provides a secure hold while keeping your hands free. When needed, the Sport Leashs hand wrap quickly converts to a traditional handle with the snap of a button. The built in bungee section helps lower leash tension and reduces the impact of sudden pulls or jolts of active pets. The Sport Leash is perfect to use with PetSafe Martingale Collars,
