Who says learning can't be fun? With the Dog Tornado Plastic Interactive Dog Toy, you can stimulate your pup's brain and have a blast at the same time! The unique and interactive toy has four layers of rotating discs. There are compartments where treats can be hidden in three of those layers. Fido has to learn to rotate the different layers in different directions with his nose or paw in order to find the hidden goodies. Increase the degree of difficulty by placing the white plastic blocks in some of the compartments. He'll love the reward of a job well done, and you'll love watching him put on his doggy thinking cap!
