Square-proportioned, compact and of a cobby build, the pug is a large dog in a little space. Its gait is strong and jaunty, but with a slight roll of the hindquarters. Its distinctive expression is soft and solicitous. Its forehead has large, deep wrinkles. Its coat is fine, smooth and short.

The Pug breed is often described by the Latin phrase multum in parvo, or “much in little” or “a lot of dog in a small space”, alluding to the Pug’s remarkable and charming personality, despite its small size. Pugs are strong willed but rarely aggressive, and are suitable for families with children. The majority of the breed is very fond of children and sturdy enough to properly play with them. Depending on their owner’s mood, they can be quiet and docile but also vivacious and teasing. Pugs tend to be intuitive and sensitive to the moods of their owners and are usually eager to please them. Pugs tend to have a somewhat lazy nature and spend a lot of time napping. They are often called “shadows” because they follow their owners around and like to stay close to the action, craving attention and affection from their owners.
