Use this product to walk two dogs on one leash or retractable leash. Each side is 18 inches long to allow both dogs to have a comfortable distance from each other, while still being manageable for you. Made from one-half inch wide premium webbing with a nickel-plated swivel bolt-snap on the end. A solid steel welded ring connects both sides. If you use a leash with a swivel snap on the end to connect to the ring, it is almost impossible for the dogs to become entangled.
