This is a normal rope and a garage door spring. The spring comes with a cable attached to it. Attach the cable to a rope, and the spring to something high up such as a tree, porch, deck, swing set, high enough so that the rope dangles 3 to 5 feet from the ground. Start out low so that your dog gets use to it. Raise it up so that he has to jump to get it after a while. Your dog will spend a lot of time on it. NOTE: Springs come in different gauges according to pounds, get the one that fits closest to your dogs weight.
These are assorted KONG toys, the black ones are suppose to be the toughest, my dogs go through the red ones pretty fast. NOTE: AS your dog tears these up, and they will tear these up, make sure , and make DAMN SURE your dog is not swallowing the pieces.
