Interactive fun for both dog & owner with the Dog Tornado! The idea behind the Dog Tornado is for the dog to dislodge the removable bones, then turn the revolving sections to reveal hidden treats. The Tornado has many variables to increase the level of difficulty as the dogs skill improves. With a little practice he will soon learn to dislodge the bones & turn the Tornado to access the rewards. The concept is for the dog to work out how to move the pieces with its nose, paws or tongue so this product is suitable for dogs of all sizes. Manufactured from high quality plastic.
