The HO Sports Dog Tow Tube is built for fun days on the lake. Even though it can handle up to 3 riders, it can easily be ridden by just 1 or 2. It comes with a heavy-duty PVC bladder and a heavy-duty Boston valve for quick and easy inflation and deflation. The center rider sits on the deck of the tube while the outside riders lay in the prone position. This towable tube is built with only the finest materials and guaranteed with HO Sports' 1 year warranty. The HO Sports Dog Tow Tube will keep you where you want to be, on the water.
