Well, The KONG Toy 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. KONGs come in many sizes, from very tiny to extra-large. Some are made for puppies with baby teeth, some are made for regular chewers and some are made for dogs with powerful jaws. There’s a KONG out there for every dog!
