Give your furry friend a challenge with the KONG Genius Leo Dog Toy. Named in honor of Leonardo, this treat-dispensing toy is designed to stimulate your dog’s curiosity and hold its attention. The multiple openings can be filled with kibble, treats, or peanut butter to help combat boredom and separation anxiety. This toy was designed to interlock with other Genius toys for an added challenge, too. Genius toys are great for puppies and adult dogs alike.
