Built with input from the military and law enforcement K9 communities, this leash brings you a special type of control and flexibility for your best friend. Constructed from a 1000D nylon external shell, the internal guts are made of an elastic material, bringing you a stretch from around 33 inches with no tension to 46 inches maxed out. Rex still pulling in crowds? No worries, just use the attached Heel Handle to rein them in or for training purposes. Our leash also features a quick release clasp once they do finally get to go wild and burn off the built up energy. Comes in 5 colors!
