Gentle Leader Easy Walk Harness - Black with grey chest strap Is designed to gently discourage your dog from pulling while walking on a leash. It's so simple - easy to fit, and easy to use. There is very little acclimation time or special technique required. Traditional harnesses actually encourage dogs to pull harder because of the "opposition reflex". That's the reflex that causes sled dogs to pull against pressure and do what they do. The Gentle Leader Easy Walk Harness' unique front-chest leash attachment stops pulling by steering your dog to the side and redirecting his attention towards you. And, its patent-pending martingale loop provides extra leverage for easy, relaxed control and prevents harness twisting and gapping. Key Benefits Stops your dog pulling Quick snap buckle on both the shoulder and belly straps to make it easier to get the harness on and off your dog. Soft but strong nylon and 4 adjustment points provide maximum comfort and reliable fit Made Specifically For: Training dogs who pull to walk nicely on the lead.
