The KONG Ballistic Extreme Ring is made using a multi-layered design. The Ballistic Extreme Ring has four layers of material with eight rows of stitching to create a tough and durable dog toy. It’s guaranteed to be gentle on your dog’s teeth and gums — plus it squeaks and floats for added fun. Throw it in the washing machine when it gets dirty, and keep your dog entertained for a long time. We tested the Ballistic Extreme Ring with tigers to give it a really difficult test — and it passed.
