Ethical Pet Play Strong Rubber Trident Dog Toy (6″) – A uniquely shaped, three-pronged chew toy made of the Play Strong ultra-durable rubber. This 6-inch “trident” design gives dogs multiple gripping and chewing angles, and it’s built to endure serious chewing from all sides. Like others in the Play Strong series, it has a hollow cavity that can be stuffed with peanut butter or snacks, and it provides an unpredictable bounce when thrown, offering heavy chewers a fun challenge that lasts.
