Premier Easy Walk Harness Royal/Navy (XLarge) The Easy Walk Harness is designed to gently discourage your dog from pulling while walking on a leash. Traditional harnesses can actually encourage dogs to pull harder because of the ?opposition reflex.? That?s the reflex that makes sled dogs do what they do. The Easy Walk Harness’ unique front-chest leash attachment stops pulling by tightening slightly across your dog’s chest and shoulder blades. The gentle pressure steers your dog to the side and redirecting his attention back towards you. The Easy Walk Harness never causes coughing, gagging, or choking because the chest strap rests low across the breastbone, not on the delicate tracheal area. Quality features: A quick snap buckle on both the shoulder and belly straps make it easier to get the harness on and off. Soft, but strong nylon and four adjustment points provide maximum comfort and a reliable fit. The belly strap is an attractive complementary color – making it easy to identify which strap goes over the shoulders and which goes under the belly.
