The KONG Wobbler is a pear-shaped training ball that can be filled with treats. The wobbler stands upright until the dog nudges it with its paw or snout. Then it rolls, rolls and turns completely unpredictably over the ground and distributes the food through a hole. The wobbler's unpredictable movements never get boring. The wobbler is also an excellent alternative to the food bowl. The feeding time can be extended and your dog is kept on the go at the same time.
