Pug dogs were extremely popular in the 1740's. They were the favourite breed of Count Brühl, the most powerful man in Saxony and the director of the porcelain factory. They were also the symbol of the Order of the Pug, which was founded in Germany shortly after Pope Clement XII prohibited the faithful (Roman Catholics) from becoming Freemasons in 1738.
