A light-colored dog trots across a pebble-strewn shore under a bright blue sky with scattered clouds. In the foreground, a large, yellow buoy with green algae growth sits in a shallow pool of water. A heavy metal chain, partially submerged in the water, connects to the buoy and stretches across the pebbles. Another smaller yellow buoy and several orange buoys are visible further out in the water. A concrete bridge spans across a body of water in the background, with buildings lining the distant shore. The scene appears to be located in the Adur district of West Sussex, United Kingdom, likely near the estuary. The tide is out, revealing the rocky shoreline and the various marine debris.
