two dogs interacting in a dog park at night

two dogs interacting in a dog park at night. A small, light brown dog is jumping at a large, white dog standing on a small, elevated mound of dirt or sand. The white dog appears to be watching the smaller dog. The dog park is lit by streetlights and surrounded by trees, with benches and fencing visible. A person is sitting on a bench in the background. Sirens can be heard in the audio.
