The Phrase "pug" intended "small cutie" in English from the 1500s. Through the 1600s, it took on the indicating of "monkey," "sprite," or "imp." It wasn't right up until the mid-1700s that the term "pug" meant "a dwarf style of Puppy." Pugs are affectionate and love to clown around. https://www.dariusreed.com
