The Magic Link can be worn as a belt, a bandolier, or a wrist-strap and it can serve as a slip-on collar or a conventional leash when attached to a separate harness. It is the key to worry-free, hands-free outings with your dog—whether it's coffee in one hand and your phone in the other while your pup leads the way home, or picking up your pooch's poop without fumbling with the leash.
