The truth of how the Pug came into existence is shrouded in mystery, but he has been true to his breed down through the ages since before 400 B.C. Authorities agree that he is of Oriental origin with some basic similarities to the Pekingese. China is the earliest known source for the breed, where he was the pet of the Buddhist monasteries in Tibet. The breed next appeared in Japan and then in Europe, where it became the favorite for various royal courts.
