A small, fluffy white dog with messy fur is sitting on a soft pink blanket. The dog looks directly at the camera with a sleepy and adorable expression for 1 second. The dog's size and position remain consistent throughout the animation. Slowly, it lowers its head and gently buries its face into the blanket, as if too tired to stay awake. The scene has a warm and cozy atmosphere, with soft indoor lighting highlighting the dog's fluffy texture. Ensure smooth, realistic movements, and maintain the dog's size and placement to avoid distortion or unnatural effects.
