The dog is medium-sized with a black and white coat. It moves quickly around the yard, sniffing the ground and exploring the area. The yard is surrounded by a wooden fence, and there are trees and bushes visible in the background. The lighting is dim, but the dog is clearly visible due to the camera's infrared capabilities.
