The Puppy KONG dog toy was specially designed for the needs of puppies' developing milk teeth. Its unique natural rubber formula is the softest of all KONG rubber toys. Specifically tailored to the needs of your puppy's 28 milk teeth, this toy encourages healthy chewing behavior. The toy's unpredictable bouncing and jumping action stimulates your puppy's mental development and satisfies their natural play instinct. The filled Puppy KONG keeps puppies occupied and entertained, giving dog owners a well-deserved break to relax and attend to their own needs.
