I thought these would be a good semi-disposable dog toy. At first they would pop out of my Belgian Malinois' mouth when he bit down hard enough, then he learned how to pin them down against the floor. With his new technique, he can destroy one of these balls in less than 2 minutes. These are NOT dog toys, let's get that straight. Hence the 5 star review. But don't expect them to hold up to aggressive chewers for long if you do offer them to a working dog as a play toy.
