The KONG® Flipz™ dog toy rolls and tumbles when nudged by the dog. Snacks are released as it spins and moves, awakening the natural foraging instinct and providing mentally stimulating play. Unpredictable movements and squeaking sounds provide long-lasting interest. KONG® Flipz™, when filled with dry food, can be used to slow down food intake for weight control. The removable centre bin is easy to clean and fill for convenient and clean foraging play. Note: Please never leave the pet unattended while playing. No toy is indestructible. To prevent injuries, the toy should be checked regularly for damage or loose parts and replaced if necessary.
