The Chewproof Leash, made of 6 feet of 3/8-inch galvanized aircraft cable, prevents even the wiliest canine escape artist from gnawing his way to freedom. The leash is coated in vibrant reflective colors for visibility, safety and smooth handling. It's lightweight and waterproof with a cushioned handle that unclips to secure Fido to a post when you duck into the general store.
