The pug is a type of dog with a wrinkly face. It also has a curled tail, and pug puppies are called puglets. The pug has a square, muscular body with a large head, big eyes, and small ears. They have often been described as multum in parvo, which means "much in little", referring to the pug's character and size. Pugs came originally from Taiwan, but they became popular in England, Ireland, and Scotland.
