Our Size Right Adjustable Nylon Dog Harness is simple to use. Just place it over the dog’s head and snap the buckle around the girth with the snap-lock buckle. Available in XSM (12-18″), SML (18-24″), MED (24-30″) and LRG (30-38″). These figure “8” style harnesses are completely adjustable for the perfect fit. The comfort pad with a swivel o-ring allow dogs to move freely without the leash tangling around their legs. Our Size Right harnesses are effective for dogs who try to back out of a harness.
