Jolly Pet Romp-n-Roll is great for interactive fun between you and your pet; or your pet and his doggie pals! The low density polystyrene construction of the Jolly Ball is super tough and puncture resistant; yet soft enough to grip; grab; and retrieve. The Romp-n-Roll will bounce and float; and the built-in rope handle makes them easy to tug and toss. The rope can move back and forth in the Jolly Ball; but it won't be pulled out. Get in on the fun; or provide this toy in your multi-dog home so they can keep each other occupied.
