The Jolly Pets Tuff Treader Dog Toy features a clever design that’s similar to the ever-popular Jolly Ball, but in a treaded tire form. This durable chew toy is made from a specially formulated “tuff” blend of thick natural rubber to keep determined chewers mesmerized. The unique raised tire tread surface helps clean your doggy’s teeth as he enjoys gnawing on the toy. You can even stuff the deep grooves with his favorite treat to keep him coming back for more.
