KONG® SHIELDS TROPICS are sealed with an extremely durable coating for longevity. The exterior of these fun friends protects the densely packed interior and provides dogs with a multi-faceted activity that satisfies their natural chewing instincts. A squeaker ensures long-lasting fun. These durable playmates are easy to wipe clean, making them ideal for indoor and outdoor play. They are also buoyant and therefore provide varied fun even in the water. Note: Please never leave the animal 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.
