A small, long-haired dog, predominantly white with dark grey patches on its head, ears, and back, is positioned inside a pet stroller. The dog's mouth is wide open, revealing an extended and upward-curled pink tongue with visible teeth. Its eyes are wide and directed towards the viewer. The pet stroller features a beige fabric body with black mesh inserts on the canopy and sides, and metallic gold-colored frame elements. A black zipper is visible on the partially retracted canopy. A brown, rectangular patch with the text "Jienyone" (partially legible) is affixed to the side of the stroller. The background consists of a light-colored, possibly tiled or polished floor, and blurry architectural elements including a light brown paneling section on the left and a vertical metallic surface, resembling an elevator door, on the right. A cylindrical metallic object is partially visible in the upper left background. The specific location within Mexico City cannot be determined from the provided image.
