This design shows three cartoon-style dogs standing close together near the bottom of a pale green gradient background, their matching green glasses giving them a friendly, in-on-the-joke look 💚. The left dog is caramel-colored in a long-sleeved green shirt with a shamrock on the chest, leaning slightly toward the others as if posing with friends. In the middle, a chocolate-brown dog wears a green bandana and smiles with its mouth open, a small tongue showing like it just cracked a joke. On the right, a white-and-warm-brown dog wears a green striped sweater, angled inward so the trio feels like a tight little group ☘️. Above their heads, four green three-leaf clovers float across the upper area, spaced like confetti. The greeting text, “Happy St. Patrick’s Day! Dear Dad,” sits below the dogs in bright green lettering, centered and easy to read. The scene is evenly lit with smooth shading, and the green accents in the clothes, glasses, and clovers stand out against the soft background. Four small clovers are scattered in the top half while the three dogs line up along the lower edge in coordinated green outfits.
