The Mammoth TireBiter Retriever is constructed of real-tire-tough made from natural rubber with 2 ply nylon. Attached to the body of the retriever is a poly-dri rope that functions as a handle so that traveling and playing with your dog is easier. The toy can be used to play fetch, chew, tug, chase and tease your dog. The retriever floats so you can move your play to be closer to a body of water. The length of the retriever body is 11" and that does not include the rope attached.
