In the video, a brown dog is seen running in a backyard. The dog is wearing a red collar and is chasing after a red ball. The backyard is enclosed by a wooden fence and there are trees visible in the background. The dog runs back and forth, trying to catch the ball, and at one point, the ball rolls under the fence. The dog then jumps over the fence to retrieve the ball. The grass in the backyard is green and there are no other objects or people visible in the video.
