KONG is a proprietary, pet-safe, built-to-chew rubber that dogs love. The way it bounces keeps them engaged and ready to play. It has a soft mouth feel for a satisfying chew and, of course, it’s super durable. Owners love KONG too; they can stuff it, throw it, leave it out in the yard — KONG keeps coming back for more. KONG toys are the best of the best in quality, originality, variety, safety, and value.
