In the video, a black and white dog is seen playing with a green ball outside a house. The dog picks up the ball with its mouth and walks up the stairs to the house. The dog then stops and looks around before walking back down the stairs and placing the ball on the ground. The dog then picks up the ball again and walks up the stairs to the house. The dog repeats this process several times, picking up the ball and walking up the stairs, before finally walking away from the house with the ball in its mouth.
