The Terrain D.O.G. Oiled Harness Leather Hybrid Dog Collar is an industry-first product that provides the even pressure distribution of a flat collar with the no-tangle benefits of a rolled collar - and you'd be hard pressed to find a collar thicker than this one. Precise stitching adorns this weather-resistant leather collar and its matching leash. This 1 in. wide collar end tapers into a 3/4 in. wide center. This collar is approximately 3/8 in. thick in the center. The Terrain oiled harness collar features aluminum-finished hardware that stands up to rugged use.Satisfaction Guaranteed
