Create five unique dog emoji designs, each expressing a distinct emotion. Each emoji should have a simple, cartoon-style face with expressive features to convey: Happiness – A smiling dog with bright, wide eyes, a wagging tongue, and perked-up ears. Anxiety – A worried-looking dog with slightly lowered ears, raised eyebrows, and a small frown, possibly with sweat drops. Excitement – A dog with wide, sparkling eyes, an open mouth, tongue out, and ears standing up, showing eagerness. Fear – A scared dog with wide, trembling eyes, ears pinned back, and a small, closed mouth, possibly with a tear or shivering motion. Affection – A loving dog with heart-shaped eyes, a small smile, and relaxed ears, possibly with a paw reaching out or a blushing effect. Use bold black outlines, warm brown and tan tones, and simple but clear facial expressions to enhance each emotion. Keep the design cute, clean, and easy to recognize in a small emoji size. emoji | AI Emoji Generator
