Not only puppies like to chew - and chew a lot - on their toys, adult dogs still have a natural instinct to chew. The KONG® Shells™ dog toy allows your dog to satisfy this urge safely and without risk of injury and protects your shoes and furniture. So it's best to offer your dog a sturdy chew toy like the KONG® Shells™. It has been specially developed to be particularly interesting for chewers. The KONG® Shells™ achieve this through the different textures, the soft plush, the robust structural fabric and the elastic nubs. All this makes chewing particularly fun, but that's not all. A squeaker is integrated in the belly of the KONG® Shells™, which squeaks when played with and encourages your dog's play instinct. Because a dog's mouth is very sensitive, the KONG® Shells™ are specially made from materials that are gentle on the teeth and even clean them very gently. Note: Please never leave the pet unattended while playing. No toy is indestructible. To prevent injuries, the toy should be checked regularly for damage or loose parts and replaced if necessary.
