The WHIPPY Leather Dog Collar is perfect for small, medium, or large dogs. Made of high-quality leather, it is flexible and super soft. The durable outer leather dog collar is stitched to an inner breathable PU leather, which is ultra-soft and could make the neck dry all the time. The metal buckle and d-ring are made with surgical grade stainless steel hardware that’s lacquered to prevent rust and corrosion. The inner layer of the leather collar is made of breathable waterproof cloth, which reduces friction on the dog’s skin and makes it comfortable. The durable dog collar is available in four sizes, suitable for dogs of all sizes.
