Dogs love to chew, and this toy is designed with determined chewers in mind. The extra-wide ends of the Woofer protect a single ultra-thick rawhide treat ring. The ring is 4x thicker than our regular Busy Buddy rawhide rings. The toy design makes it more difficult for dogs to get a grip on the rawhide. This difficulty combined with the ultra-thick rawhide rings means this toy will hold a dog’s interest for an ultra-long time.
