(No background music, maintain character consistency throughout the video) The young man follows the Golden Retriever back into the living room and immediately kneels beside the elderly man lying on the floor. He checks the older man's vital signs while urgently making a call on his cell phone. The scene transitions to a bright hospital room where the elderly man is now sitting up in a bed, smiling. The young man is standing beside him, and the Golden Retriever jumps up, affectionately licking the older man's hands and face. Both men smile warmly at each other and the dog, showing relief and gratitude.
