I have the almost indestructable ball, the eGGe toy, and the goughnut
(this is guaranteed if destroyed they will replace as well as the kong. They love all of them and as of yet (knock on wood) haven’t been able to destroy them. Both of my boys are very hard chewers. As a treat I fill the kong with kibble mixed with peanut butter or fill it with yogurt and freeze it for a special treat. They get very excited over these interactive toys.
