The main leash is 5 feet long and is constructed of very strong and soft TWO inch military grade tubular nylon webbing, with a comfortable handle at one end and a solid metal bolt snap at the other. The restraint collar is made from ONE inch durable nylon strapping which runs through the length of the leash with a handle at one end and a restraint collar at the other end. The metal bolt snap is intended to be attached to your dog's harness or collar, and the noose is then slipped over the dog's neck. This is a very strong leash adequate for any dog, and provides a restraint collar as an option only when needed. This is for VERY LARGE dogs!!
