A white Pit Bull type dog, wearing a dark blue harness, lies on its belly on a verdant green lawn, with its front paws extended. The dog holds a light green tennis ball in its open mouth, with its tongue partially visible. A distinct shadow of the dog is cast to its right. In the midground, a gently sloped grassy embankment rises, featuring three evenly spaced, tall white poles, each topped with a light-colored, flattened spherical fixture, consistent with modern streetlights or markers. Beyond the embankment, a wide, dark body of water, identifiable as the Rio de la Plata, extends to the horizon under a clear, cloudless blue sky. This scene is located in a public green space along the Costanera waterfront in Buenos Aires, Argentina.
