Art style: Cinematic Realistic.
A vertical 9:16 shot inside a modern, bright, high-end fitness gym. A tall, sleek solid light-grey Greyhound stands stoically on a high-tech running treadmill, wearing sleek black over-ear sports headphones with an intense, disciplined look. Standing right beside the treadmill control panel on a raised platform is a tiny light-brown Chihuahua dressed like a strict coach with a tiny metal whistle hanging from its neck, flashing a sly, mischievous human-like smirk at the camera. Crisp cinematic lighting, photorealistic 8k detail, vivid colors.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Cinematic Realistic" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Cinematic Realistic". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "Cinematic Realistic" idiom, not in any other medium.
