The KONG is a nontoxic, dishwasher-safe rubber toy with a hollow center. When stuffed with food, it provides dogs with a healthy outlet for their natural desire to chew and lick. You can stuff KONGs with almost any kind of food your dog likes. Feed him his meals in a KONG by mixing his regular kibble with a little canned dog food, cottage cheese, yogurt, peanut butter, canned pumpkin or mashed banana. After spooning the mixture into the KONG, you can use a bit of cream cheese or peanut butter to seal everything in. You can also fill your dog’s KONGs with special snacks to supplement his diet.
