Because we understand canine growth, structure and movement, our hand-crafted leather tracking harnesses fit like a quality leather tracking harness should fit. Our tracking harness designs allow all straps to follow the body contour, making for unbeatable comfort and for full range of motion of the head, neck, shoulders and legs. Because our tracking harnesses fit properly and allow for a dog's body growth and change as he matures and ages by adjusting in several strategic locations, your dog can be free from the hair loss, rubbing and skin burns he experiences when wearing inferior harnesses. You won't find better quality leather tracking harness designs made of better quality materials. We guarantee it.
