(No background music, maintain character consistency throughout the video) The Golden Retriever sprints down an old apartment stairwell with concrete steps and a metal railing. It reaches the building's exterior glass door. Outside, a young Caucasian man (approx. 30s) in a dark jacket and jeans is distracted by his phone. The Golden Retriever urgently barks at him and jumps up, placing its paws on the man, then runs back toward the door, displaying a clear, distressed appeal for him to follow.
