Have you ever been entwined by the dog leash when you and your dog take a walk? Or have your dog runs across a public chair and winds the dog leash around it? More-free dog leash changes the traditional form of leash. It has double hooks and works as a pulley. When the leash entwines to something, you can untie it easily within a few seconds. You only need to fasten the free end of dog leash to dogs collar and loosen the end buckled previously. Then, the dog leash will automatically untie with the dog running away. This kind of leash will bring you and your lovely dog more freedom.
