The distinctive »stand-up man« function encourages the dog to play. To reach the snacks inside, the dog has to skillfully move the toy back and forth so that the snacks fall through the side opening. The KONG® WOBBLER™ provides lots of fun and can be cleaned in the dishwasher. 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.
