Brain games your dog will love.

You know your doggie is smart, so challenge him with Nina Ottosson's puzzles and interactive games. These learning tools not only prevent Fido from getting bored and resorting to bad behaviors, but they're also a great way for you two to bond.

Try the Dog Tornado — equipped with four layers of rotating discs, this game has three layers of compartments where treats can be hidden. Watch as your woof uses his nose or paw to move the discs and find the treats. White plastic blocks can be added to the slots to increase difficulty.
