Description of a Pug.

Bred to adorn the laps of the Chinese emperors during the Shang dynasty (1766-1122 BC), in East China, where they were known as "Lo-Chiang-Sze" or "Foo" (ceramic foos, transmogrified into dragon, with their bulging eyes are very Pug-like). The Pug's popularity spread to Tibet, where they were mainly kept by monks, and then went onto Japan, and finally Europe.

Professor Ludvic von Schulmuth studied canine origins by studying the skeletal remains of dogs found in human settlements as long as ten thousand years ago.[citation needed] Schulmuth created a genealogical tree of Tibetan dogs that shows the "Gobi Desert Kitchen Midden Dog", a scavenger, evolved into the "Small Soft-Coated Drop-Eared Hunting Dog". From this dog evolved the Tibetan Spaniel, Pekingese, and Japanese Chin.[citation needed] Another branch coming down from the "Kitchen Midden Dog" gave rise to the Papillon and Long-haired Chihuahau and yet another "Kitchen Midden Dog" branch to the Shih Tzu and the Pug.
