Generate a lively scene of a baby dog eagerly starting to play just before the rain begins. The puppy should be depicted with an excited and alert expression, its tail wagging and ears perked up as it senses the impending raindrops. Show the puppy standing on a patch of grass, perhaps with a ball or toy nearby, ready to engage in a playful activity. Depict the sky darkening with storm clouds and a few raindrops starting to fall, creating a sense of anticipation and excitement in the air. Place the scene in a natural outdoor setting, with trees swaying in the wind and the scent of rain filling the air, adding to the overall ambiance of anticipation and excitement. Ensure that the image captures the puppy's enthusiasm and readiness to play, evoking a sense of energy and anticipation in the viewer.
