In the video, a small dog is seen playing with a red plastic cup. The dog is wearing a red bow on its head and is standing on a carpeted floor. The dog appears to be biting and pawing at the cup, and at one point, the dog picks up the cup with its mouth. The dog's fur is a mix of black, brown, and white, and it has a small, pointed snout. The red cup is the only object the dog interacts with in the video.
