The pug is a breed of dog with physically distinctive features of a wrinkly, short-muzzled face, and curled tail. This 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.
