The Great Backyard Pool Lifeguard

Produce a sunny 13-second vertical comedy video about a serious-looking bulldog acting as lifeguard at a backyard pool party. The dog wears red sunglasses and a tiny whistle while sitting on a raised chair, carefully supervising inflatable ducks and a floating tennis ball. Begin with a 24mm wide poolside shot, use a smooth 50mm lateral camera move past colorful floats, then cut to a 85mm close-up as the bulldog blows the whistle at the drifting ball. Use bright midday lighting, saturated summer colors, realistic water sparkle, subtle handheld movement, and playful beach-party music. Make the dog relaxed, safe, and clearly enjoying the scene.
