Keep your inquisitive pup engaged and entertained with the Nina Ottosson by Outward Hound Puppy Tornado Dog Toy. This interactive dog puzzle is a fun way to enrich your dog's playtime and get him excited about problem-solving games! The level two intermediate dog puzzle keeps your pal busy with treat-focused challenges that stimulate his senses and tap into his natural instinct to hunt and forage for food. It provides mental and physical exercise, helps relieve stress, and reduces boredom for a happier, healthier pup. There are three tiers with 12 treat-hiding compartments that you can fill with your pup's favorite dog treats to motivate him to spin the layers and solve the puzzle. Plus, you can make this puzzle easier or harder to match its difficulty level to your dog's problem-solving ability—three bone treat compartment covers are included to increase the challenge. Best of all, this toy is easy to clean and made from food safe composite materials that are BPA, PVC, lead, and phthalate-free. For safety, make sure to choose a toy that is the appropriate size and level for your pup and always supervise your dog while he plays.
