Playful Australian Shepherd Racing Outdoors with a Tennis Ball

Ultra-detailed photorealistic image of a playful Australian Shepherd joyfully racing across a sunlit park. The tri-color coat shines as the dog sprints after a bright neon yellow tennis ball clenched in its mouth, ears forward, tongue lolling. Wind-swept grass blades and a puff of dust swirl around the dog's powerful paws. A clear blue sky, lush green trees, and distant parkgoers provide a soft bokeh background. Capture with shallow depth of field and cinematic lighting to emphasize speed: motion blur on the legs, crisp fur texture, and vivid colors. Perspective from a low angle at the dog's eye level, about 85mm focal length, to convey energy and joy.
