Bred to adorn the laps of the Chinese emperors during the Shang dynasty (1766-1122 BC),[4] in East China, where they were known as "Lo-Chiang-Sze" or "Foo"[4][5] (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.[4]
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 Chihuahua and yet another "Kitchen Midden Dog" branch to the Shih Tzu and the Pug.
