A dog leash having a stiffener and a mast, the latter connected to a clamp by a flexible coupling. Moored to the clamp by a cord, the stiffener protrudes outwardly from the mast's end distal from the clamp. Built up by encasing a cord segment and the base of a clip in a semi-rigid plastic sheath, the stiffener directly links the clip to the mast. Because, in use, the stiffener and the clip ride attached to the dog's collar without slapping or flopping around randomly so as to confuse the animal, the leash can transmit nonverbal communication free of extraneous signals from the user of a personal carrier to a tethered dog. The dog can be then trained quickly and easily controlled, making possible the leash's use not only on bicycles but also, once they have been retrofitted with a universal mounting bracket, on wheelchairs and other personal carriers.
