Seedance 2.0 text to video, 15 seconds max, ultra realistic 8K, same frame, no cuts, fixed camera in a front porch. A tiny energetic Chihuahua and one big grey bully dog stay visible in the same frame from start to finish. The scene begins with a snack bag crinkles on the floor from air movement, looking completely normal and realistic. The Chihuahua suddenly reacts and the Chihuahua barks at the sound, making the moment feel like a real funny pet video, not cartoonish. The grey bully dog stays calm, sleepy, and confused, creating a strong size and personality contrast. Halfway through, the bully dog noses the bag and looks disappointed it is empty, while the Chihuahua keeps barking even harder like he is trying to control the situation. Keep the dogs' movements natural: tiny hops, head tilts, paw steps, sniffing, blinking, and realistic body language. Add sharp tiny barks, bully dog sigh, floor taps, subtle comedy timing sounds, with clear funny timing and no exaggerated cartoon noises. End with the Chihuahua acting proud or shocked while the grey bully dog gives a tired side-eye look. Make it feel like a viral realistic home pet clip, clean lighting, detailed fur, natural shadows, no cuts, no text on screen. Variation 2.
