The Orbee-Tuff Mazee is clearly engaging, clearly rewarding, and clearly fun! This interactive puzzle toy offers hours of long-lasting, brain-stimulating entertainment for dogs of any size. The translucent and pliable Orbee-Tuff outer shell combined with the harder inner maze activates several of the dog's senses - they can hear, see and smell the treats while they solve the puzzle. Stuff with Planet Dog Eats and enjoy! Mazee is designed to activate a dog's mind and energize its play. Guaranteed to stimulate, spark, and excite! Although Mazee is built for durability, it's intended for puzzle-play, not chewing, so it is not rated on our Durability Scale. Mazee is not to be left with dogs unattended. Available in raspberry and green. 5" in diameter. Easy to clean by hand, or on the top rack of the dishwasher.
