Rainbow set is a dog puzzle that will keep your dog entertained as they use their natural hunting skills to find hidden treats. The set includes treat-hiding mechanisms that require slide pushing, lid lifting, pulling, and lid turning. Each set includes at least one base which holds individual pawzles. You can fill the compartments with treats, regular dog food, or even peanut butter for your dog to find. Hint: If you turn yellow and orange pawzles in different directions, you can change the toy’s difficulty level.
