Designed for active play and long-lasting durability, the GoSports Pets Solid Rubber Exercise Ball Dog Toy is made from heavy-duty natural rubber that stands up to enthusiastic chewing. Compatible with most standard tennis ball launchers, these heavy-duty balls make an excellent alternative for all your toss-and-fetch sessions. Their solid rubber construction resists tearing or breaking apart, while the high-visibility colors make retrieval easy during outdoor play. A center channel allows pet parents to fill the ball with peanut butter or other treats to keep dogs engaged, and a small air hole prevents suction. The non-porous surface easily rinses clean with water for hassle-free hygiene, too. Upgrade your pup's playtime with this durable, easy-care dog fetch ball.
