Nina Ottosson Hide N' Slide Puzzle vs Nina Ottosson Tornado Puzzle

Both are Level 2 Nina Ottosson puzzles from Outward Hound, so build quality and BPA-free plastic are effectively the same. The Hide N' Slide is a flatter board where dogs slide compartments and lift flaps, while the Tornado is a raised, tiered tower that spins and drops treats through levels. Owners of clever, food-driven dogs tend to get more mileage from the Tornado's rotating layers; the Hide N' Slide suits dogs that paw and nose at flat surfaces. Pick by your dog's style of working, not by brand.

• Choose the Hide N' Slide if your dog paws and noses at flat surfaces and you want a compact board that slides and hides treats under flaps.
• Choose the Tornado if your dog is quick to solve flat puzzles and you want a taller, spinning tower that adds a step-up in challenge.
