The JW Pet Invincible Chains Double Link Tug Chew and Fetch Rubber Dog Toy is available as a Two-large interlocking rubber ring or Three-Small Interlocking Rings designed for vigorous tug-of-war and chewing. This toy uses JW’s patented no-seams construction: the rings are molded as one piece, so there are no weak points or glue joints – meaning even the strongest tuggers won’t pull them apart. The durable, springy rubber is enjoyable for dogs to chew (providing that beloved rubbery resistance) and holds up to aggressive chewers. Great as a tug toy between you and your dog or between two dogs, the double rings also work as a heavy-duty chew toy that can help clean teeth and massage gums during play. It’s basically two tough toys in one, built for large breed power players who need a challenge. Available in Multiple Sizes
