A cheerful border collie stands on its hind legs with one paw playfully raised, eyes bright and tongue lolling in joyful pant. Classic black and white coat, slightly cartoonish anatomy, dynamic pose angled for movement. Vibrant red bandana tied loosely around neck adds bold color contrast. Rendered in full color with flat shading, bright primary palette, clean lines, and soft even lighting. Background is solid white to keep focus on the dog. Highly stylized, whimsical children's book illustration style-exaggerated features, expressive emotion, and polished finish.
