In the video, a black dog is seen standing on a wooden floor next to a white cage. Inside the cage, there is a white and tan guinea pig. The dog sniffs the guinea pig and then starts to play with it. The guinea pig moves around the cage while the dog watches and sniffs it. The dog appears curious and playful as it interacts with the guinea pig. The cage is placed in a room with a green chair visible in the background. The lighting in the room is natural, and the video is shot from a side angle, capturing the interaction between the dog and the guinea pig.
