The Pug’s attentive and soft expression is its distinguishing feature. Its coat, which is fawn and black in color, is short, fine, and smooth. A compact and square-proportioned dog, the Pug moves with a jaunty and strong gait; its hindquarters roll slightly. The Pug also has clearly defined black markings on its muzzle, ears, cheeks and forehead, which has deep and huge wrinkles.
