The red KONG® CLASSIC made of solid rubber is extremely robust and hard-wearing. Due to its special shape, it jumps around irregularly and thus offers the animal a special incentive to play. It is ideal for retrieving. Thanks to its opening, it can also be filled with snacks as desired. 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.
