KONG Extreme Goodie Bone, Durable Natural Rubber Dog Bone, Medium Review (2026)

Who this bone fits

KONG builds the Extreme Goodie Bone in multiple sizes, and this Medium measures about 7 inches long, which KONG positions for dogs in roughly the 15 to 35 pound range rather than small toy breeds or large power-chewing breeds. Because it is made from KONG's Extreme rubber formula, the same durability tier used in KONG's toughest treat-dispensing toys, it is aimed specifically at dogs that have already destroyed standard rubber or plastic chew toys rather than light or occasional chewers who would do fine with a softer bone. A dog on the upper edge of the medium weight range with an especially strong bite may still be better matched to the Large size.

Material and design

The bone is molded in one piece from KONG's black Extreme natural rubber, the company's most durable rubber compound, and shaped like a classic dog bone rather than the ball or Kong-shape toys the brand is also known for. Two Goodie Gripper holes run through the bone, each designed to hold treats, paste, or kibble, turning what would otherwise be a straightforward chew toy into a slower treat puzzle when it is stuffed. This stuffing feature is what separates the Goodie Bone from KONG's plain Extreme bone, giving it a second use as a mental enrichment toy beyond simple chewing.

Using the treat feature

Owners commonly load the Goodie Gripper holes with a smear of peanut butter, a portion of wet food, or plain kibble to extend how long a dog stays occupied with the bone, since digging treats out of the grooves takes more effort than eating from a bowl. Because the holes are open rather than fully enclosed like KONG's classic hollow shape, they are easier to load and easier to rinse clean afterward, though sticky fillings can still work into the grooves and need a proper scrub rather than a quick rinse. This makes the bone reasonably low-maintenance as enrichment toys go, provided it gets cleaned after each stuffed use.

Durability for power chewers

The Extreme rubber line sits above KONG's standard red rubber in the brand's own durability tiers, so this bone is meant to hold up to more aggressive chewing than KONG's entry-level toys, though KONG does not claim any rubber toy is fully indestructible against every dog. As with any chew toy, supervision during the first few sessions is worth doing so an owner can judge how their particular dog's bite compares to the bone's durability before leaving it unsupervised. Dogs that have already gone through several standard chew toys are the clearest fit for stepping up to this Extreme-rated bone.

Where it comes up short

The Medium size is built for the 15 to 35 pound range, so large breed power chewers will find it too small to provide much chewing surface and should look at KONG's Large or Extra Large Extreme Goodie Bone instead. The open Goodie Gripper holes need regular cleaning once treats or paste are used, since residue left in the grooves can attract odor or pests if the bone sits unwashed for long periods. Buyers wanting a pure fetch toy without the treat feature may prefer KONG's plain Extreme bone, since the Goodie Gripper design adds cleaning upkeep in exchange for the added enrichment value.
