KONG Duets Duos Ball (Medium) delivers interactive fun with a unique dual-material ball design. It bounces erratically to keep dogs guessing, thanks to curved features that send it flying unpredictably. The two-tone, two-texture construction provides multi-sensory stimulation: a durable, easy-grip surface and engaging tactile feel. Lightweight and squeak-equipped, this fetch toy is easy to throw far and will entice dogs to chase, fetch, and play for hours.
