Outward Hound Puppy Treat Puzzle vs Nina Ottosson Hide N' Slide Puzzle

Both are Nina Ottosson treat puzzles from Outward Hound, so build quality and food-safe plastic are comparable. The Puppy Treat Puzzle is the gentler starter, aimed at puppies and beginners with a bone-shaped board that hides treats under covers. The Hide N' Slide is a step up in difficulty: dogs slide compartments and lift flaps, which suits adult dogs that already understand a puzzle. Buy the Puppy version for a young or first-time dog; buy the Hide N' Slide for an adult dog that needs more of a challenge.

• Choose the Outward Hound Puppy Treat Puzzle if you have a puppy or a dog new to puzzles and want an easy, durable starter that builds confidence.
• Choose the Nina Ottosson Hide N' Slide if your adult dog has already solved simple puzzles and you want a harder hide-and-seek challenge.
