In the video, a small white dog with a pink bow on its head is standing on its hind legs at a piano. The dog is pressing the keys with its front paws, producing a melody. The dog appears to be enjoying itself, as it moves its paws up and down the keys. The piano is a standard upright model, with black and white keys. The dog's fur is fluffy and well-groomed, and it has a playful expression on its face. The room in which the dog is playing the piano is not visible in the video.
