A small, square and stocky dog with a large, round head, short face, deeply wrinkled forehead and a tightly curled tail. The ears are soft and velvety, rose shape preferred. The eyes are prominent, expressive, dark, and lustrous. The teeth should meet in a slightly undershot bite. The back is short, with a level topline. The tail curls tightly, resting on the hip. A double tail curl is highly desirable. The Pug's smooth, fine glossy coat gives him a well-groomed appearance even with minimal brushing. Coat colors are fawn, silver, or black with black mask and other black markings including a black "trace" (a line running from the occiput to the tail).
One of the older breeds, the Pug is believed to have originated before 400 BC in Asia. He was a pet at Tibetan monasteries and later traveled to Japan. The Pug then came to Europe, where the endearing little dog was the pet of royalty in several countries and even became the official dog of the House of Orange in Holland. A Pug saved the life of William, Prince of Orange, by alerting him to the approach of the Spaniards in 1572 at Hermingny. Napoleon's wife, Josephine, sent secret messages to her husband under the collar of her Pug while she was in prison. When the British overran the Chinese Imperial Palace in 1860, they discovered several Pugs and Pekingese, and brought the little dogs back to England with them. The AKC recognized the Pug in 1885 and the breed has since become a popular companion dog.
