The image features a cartoon dog character, which appears to be a Snoopy-like figure, standing upright and smiling. The dog is wearing a red heart on its shirt. Above the dog, there is a banner with the text "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 cartoonish, with a clear focus on the theme of Valentine's Day.
