Having a dog adds a massive amount of joy to life. The box-and-cross stitch construction with tapered seams creates a smooth transition between layers, making the Martingale extremely strong! Not only a great training collar, the Martingale’s cinching action can also help prevent your pup from backing out of their collar during walks. Wolfgang products are tested to withstand over 800-lbs of pull and our D-rings are welded so your furry best friend can’t slip away when on their leash. The bolt snap design is made of super strong steel and is powder-coated with a swivel to keep your leash as un-tangled as possible. We know your dog gets dirty no matter how hard you try to keep them clean, so Wolfgang products have been made with long lasting, fade-resistant, washable polyester and are UV stable. Clean your collars, harnesses, and leashes with warm water and dish soap, and the color will always stay vibrant. Wolfgang was created to celebrate the unique relationship between dogs and their people. We offer American-made leashes, collars, and harnesses for your pup using only the finest American leather and textiles. Select collaborations with artists and photographers, plus world-renowned athletes and entertainers, provide the inspiration for modern timeless designs. Unparalleled American craftsmanship ensures supreme quality and years of enjoyment. We build our products domestically, transport them minimally, and they’ll be replaced rarely.
