Easy Walk Harness Easy to fit, easy to use, with very little acclimation time or special technique. Does not cause coughing, gagging or choking because the chest strap, where you fasten the leash, rests low across the breastbone, not on the delicate tracheal area. The unique front-chest leash attachment stops pulling by steering your dog to the side and redirecting his attention toward you. The martingale loop provides extra leverage for easy, relaxed control. Quality construction, with soft nylon webbing.
