ultra-realistic cinematic video, warm and emotional tone: A dog with moist, teary eyes slowly approaches the camera, followed by a tender close-up of its face. It nuzzles the camera affectionately, as if acting coquettishly toward its owner. Then it turns around reluctantly, steps onto a vibrant rainbow staircase that ascends into golden clouds. After walking 5 steps, it pauses, looks back at the camera, and lifts one paw to wave goodbye. Soft golden sunlight shrouds the scene, warm dreamy color palette, no text overlay.
