The video shows a small brown dog running on a green lawn. The dog is wearing a collar and appears to be happy and energetic. The lawn is well-maintained and the dog is the only one in the frame. The dog's fur is short and smooth, and it has a long tail that wags as it runs. The dog's ears are perked up and its mouth is open, possibly panting from the exercise. The background is blurred, but it appears to be a sunny day with no clouds in the sky.
