Cinematic close-up, slow motion. A fluffy Golden Retriever puppy with floppy ears is staring intensely at a white mini automatic ball launcher on a green manicured lawn. The machine makes a whirring sound, and a bright yellow tennis ball pops out. The puppy reacts a split second too late, clumsily tripping over its own paws trying to catch it, ears bouncing. Warm afternoon sunlight backlighting the puppy's fur, creating a halo effect. High quality, 8k, heartwarming atmosphere, shallow depth of field.
