Dogs have an instinct to chew. Whether it's a toy, your favorite slippers, or the legs of your sofa, chewing is simply part of their nature. With a KONG Donut, your pup can satisfy this instinct with appropriate chewing behavior. This toy is made with high-quality natural rubber, allowing it to withstand countless hours of chewing. Unlike nylon, hard plastic, sticks, and bones, rubber doesn't splinter and is gentle, helping promote healthy teeth and gums. The donut shape lets it bounce and roll, making every fetching session lively and fun! The KONG Donut is strong, but if you have a power chewer, try the KONG Extreme Donut, made from our toughest natural rubber. If your dog is an avid chewer, the KONG Donut makes playtime extra fun!
