The Dog Twister by Nina Ottosson is great for dogs that are looking for challenging treat dispensing games and toys. The Dog Twister is more challenging then the level 1 & 2 Nina Ottosson games but can be enjoyed by paws everywhere. The Twister Dog Puzzle works to combine both mental stimulation and play to maximise your dogs playtime while working to exercise their mind and body. Through treat discovery, your dog is engaged and excited to learn new tricks. Pull handles out to unlocked position to slide paw panels, place treats or kibble in compartments, lock the compartment by pushing the handles in. You can even mix some wet/raw/dry food with some water and pour it in the hollows, place in freezer and let sit. Great for energetic dogs, hot weather or just for extended fun.
