The WePet Dog Leash Slip Rope Lead Leash is a heavy duty braided rope that is perfect for training your dog or for use as a leash. Made of premium nylon and stainless steel, this rope is durable and will last you for years. The unique lock tab design prevents your pet from choking under some extreme situations, and the slip leash tightens when your dog pulls and loosens when he behaves correctly. With a 6 ft length and 3/8 inch diameter, this leash is perfect for medium-or-large-sized dogs.
