Nina Ottosson Dog Twister Puzzle vs Nina Ottosson Dog Brick Puzzle Toy

Both are Nina Ottosson advanced puzzles from Outward Hound, and the choice comes down to how much work you want your dog to do. The Twister is the harder, larger puzzle: nine sliding drawers locked by nine rotating tabs, level 3, and it holds up to a bigger dog's nose and paws. The Brick is level 2, a flatter board with sliding bricks and flip lids that suits most dogs and is easier to clean and store. Owners of both report the plastic holds up well, but determined chewers can still mark the tabs and lids.

• Choose the Dog Twister if your dog has already solved sliding and flip puzzles and you want a level 3 challenge that takes real nose and paw work.
• Choose the Dog Brick if you want a proven level 2 puzzle that most dogs can learn, fits smaller spaces, and is simple to load and wash.
