Because we understand canine growth, structure and movement, our hand-crafted leather guide dog harnesses fit like a quality leather guide dog harness should fit. Our guide dog 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 guide dog harnesses fit properly and allow for a dog's body growth and change as he matures and ages by adjusting appropriately, 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 guide dog harness designs made of better quality materials. We guarantee it.
