large, long-haired dog walking in a paved area, possibly a driveway or parking lot, at night. The dog is primarily black and gray, with some white markings on its legs. It looks towards the camera and briefly sticks out its tongue. In the background, there's a white building with a closed garage door, a doorway, and a security sign. A portion of a car is visible on the right side of the frame. The scene is illuminated by artificial lighting.
