A black, white, and brown Bernese Mountain Dog lies on the floor, seen through a glass door. The dog is looking directly at the camera with a slightly mournful expression. The floor inside is tiled, and the dog's shadow is visible on the glass. There is a dark grey or black rug or doormat at the bottom of the frame. A slight noise is heard at the beginning of the video.
