EASY WALK HARN XLG BLKPetSafe Easy Walk Dog Harness The Premier Easy Walk Harness not only lets you take relaxing walks in the park with your pet, but it also helps train him not to pull on his leash. The unique front chest attachment stops pulling by slightly tightening across the dogs chest and shoulder blades. This gentle pressure steers the dog to the side and redirects his attention back to you.
