The image features a cartoon dog character, standing upright and smiling broadly. The dog is predominantly white with black ears and a tail. It has a heart-shaped patch on its chest. Above the dog, there is a text that reads "Happy Valentine's Day" in a playful, bold font. The background is plain white, which contrasts with the black outline of the dog and the red text. The overall style of the image is simple and child-friendly, with a clear and cheerful message.
