Tie one end to a tree limb, stout beam or rafter tail and leave the rest to the dogs. The Zoing is a stretchy tubular webbing assembly that provides tugging resistance with our Lunker attached to one end. Once secured, dogs will grab hold of the Lunker and pull, but the harder they pull the harder the Zoing pulls back. It's an all day game of tug of war that is as tireless as your pup. The Zoing is a great interactive toy that will entertain your dog for hours.
