KONG's Genius Leo is a treat-dispensing puzzle toy for dogs of all ages and sizes. Named after Leonardo da Vinci, it's designed to engage a dog's natural curiosity and problem-solving instincts, rewarding persistence with treats and providing a focused distraction from boredom or separation anxiety. It works as a standalone toy or connects to the Genius Mike for added complexity.

The distinctive shape creates multiple treat-release paths, requiring dogs to work out the angles to retrieve food. Fill it with kibble, small treats, or KONG-compatible paste — the irregular dispensing keeps dogs guessing rather than learning a single routine. When linked to the Genius Mike, the two pieces form a larger, more complex structure that raises the challenge significantly. The durable rubber handles regular chewing.

A reliable tool for dogs that need mental engagement as much as physical exercise, particularly those prone to destructive behaviour when understimulated. The connectable design gives it longevity — once a dog has mastered the solo version, step up the challenge without buying something new.
