This leash was designed for Special Ops and Law Enforcement K-9 handlers. A special bungee lead belt attachment with quick release may be purchased separately and worn on your belt. The bungee lead has a ring in the handle, which attaches to the quick release belt attachment. If the dog pulls, he´ll feel the heavy bungee tension, think he's being corrected, and automatically return to the heel position. It allows you to free your hands to work your firearm, and yet still control your K-9.
