This set consists of Nai pawzles only and is an excellent addition to increase number of possible combinations on your base. Nai is a pawzle that takes up 2 spots on the base and requires pushing the lever to uncover the treat under the lid. The lever can be pushed with a dog's nose, tongue, or paw.

You can fill in the compartments with treats, regular dog food, or even peanut butter for your dog to find.
