Designed for erratic pullers, absorbing the pull pressure along the surface of the soft bungee webbing which extends and retacts accordingly to your dogs behaviour, minimizing the risk of injury to you or your dog. Rogz has designed the world's first ShocLoc system, providing an option to reduce pull load and pressure when ShocLoc system is not locked out. When you want to want to maintain close control, lock the ShocLoc system out, to prevent the bungee from stretching. With the soft touch bungee to ease the pull strength and pressure placed on you and your dog. Reflective yarn is woven into the webbing for night time visibility.
