KONG DuraMax Ball is a heavy-duty chew toy for determined chewers, made from KONG's ultra-durable K-100 material that balances structural toughness with enough flex to make chewing satisfying rather than punishing. Available in Medium and Large sizes, it features a textured exterior, internal ridges, and a built-in squeaker.

The K-100 material is engineered to withstand extended chew sessions from powerful dogs while providing enough give to engage the jaw naturally. The textured surface and ridges deliver a satisfying tactile experience and help massage teeth and gums during chewing. The squeaker adds auditory engagement that maintains interest during solo play. Suitable for dogs of all life stages. Recommended for breeds classified as strong or determined chewers.

KONG DuraMax Ball is chosen by owners of breeds that regularly destroy standard rubber toys. The K-100 material represents a step up from classic KONG rubber in durability, making it the recommended option for the most persistent chewers.
