Nina Ottosson Dog Worker Puzzle vs Nina Ottosson Tornado Puzzle

Both are Nina Ottosson by Outward Hound puzzle toys for adult dogs, but they test different skills. The Dog Worker is a larger, multi-part puzzle with swiveling fish fins and sliding pieces that suit medium breeds and dogs that like to nose and paw at moving parts. The Tornado is a compact, stackable spinner rated Level 2, better for dogs that already solve basic puzzles and need a step up. Reviewers of the Ottosson line praise the sturdy, food-safe plastic and the mental workout; owners of high-energy chewers note that determined dogs can figure either one out quickly, so supervision matters.

• Choose the Dog Worker if you have a medium breed that needs a bigger, more varied puzzle with moving fish fins and sliding compartments.
• Choose the Tornado if your dog has mastered beginner puzzles and you want a compact Level 2 spinner that stacks and turns.
