The Pug is one of the oldest dog breeds in the world. Ancient Chinese documents state that short-nosed dogs with the description matching that of the Pug existed in China at around 700 BC. These dogs were only breed and owned by the emperors. It is believed there is an ancient Chinese law whereby only the emperor was allowed to own a Pug, anyone other than the emperor could only own a pug if it was a gift from the Emperor himself.
