The KONG Extreme is a black rubber chew toy built specifically for powerful, determined chewers. It's the highest-durability rubber in the KONG range and comes in sizes from Medium through to XXLarge.

The ultra-durable natural rubber compound is formulated to withstand sustained heavy chewing that would destroy standard KONG Classic toys. The hollow interior can be packed with treats or kibble to extend engagement, and the irregular shape produces an unpredictable bounce during fetch. Chewing also provides some incidental dental stimulation.

The go-to choice for large or aggressive chewers that have destroyed other toys. Owners use it both as a standalone chew and as a stuffable enrichment tool — frozen with peanut butter or wet food to slow things down.
