In the video, a dog is seen walking around a room while holding a tennis ball in its mouth. The dog appears to be a medium-sized breed with a light brown coat. The room has a wooden floor and a large window that lets in natural light. There is a fan in the background, and a rug is partially visible on the floor. The dog seems to be enjoying its time indoors, and the tennis ball is bright yellow, contrasting with the dog's coat.
