Stainless steel rotates 360 degrees to help you suspend this exercise dog spring rope toy easily in minutes. 3[Easy To Use] We provide 5m/16.4ft size, you can suspend it on a branch or wooden beam under the deck, or wrap it around and pull it tight after wrapping it around the tree. You can adjust the height to make this interactive spring pole toy more challenging for your furry friend. 4[Safe And Durable] We pack with 1 cotton rope chew toy. The heavy duty traction chew rope is perfect for medium to large dogs and is long enough to defend your dog from biting the spring bar causing tooth and gum injuries. Small rope dog toys are suitable for puppies and smaller breeds. Rope fibers are sensitive and non irritating for gentle gum cleaning. 5[Use Note] Rope is not an indestructible chew toy, so always supervise. The action of the indoor and outdoor dog spring bars is a "shock absorber" action, not an elastic "bungee". The bottom of this dog pull toy with springs should be approximately 16 feet off the ground to ensure your dog is able to exercise their entire body without chewing on metal and their hind legs touching the ground.
