It uses voice recognition to perform 24 tricks that match the words you say. You can feed it with the included bone, it gets happy when you pet its head, and you can even play with it like you're taking it for a walk! You can also play with it like you're taking care of it! It can stand, sit, lie down, walk, bark in response, dance, and has many other movements, allowing you to communicate with it like a real pet. I am selling it because my child no longer plays with it. Everything in the photos is included. Main unit, bone, instruction manual Four AA batteries are sold separately. Please purchase only if you understand that this is a used item.
