The history of the Lo-Sze stretches back over two millennia, making it one of the most ancient companion dog lineages in the world. The story begins in ancient China during the time of Confucius, around 700 BC, when small, flat-faced dogs first appeared in imperial Chinese courts. These early ancestors were meticulously bred and treasured by Chinese royalty, who valued them not only for their charming appearance but for their exceptional temperament and unwavering loyalty.
Archaeological evidence and historical documents, including a dictionary of Chinese characters commissioned by Emperor Kang Hsi in 950 AD, provide detailed references to dogs with short legs, short heads, and short hair. These descriptions match perfectly with artistic depictions found in ancient Chinese scrolls and imperial dog books, where the Lo-Sze appears alongside other favored court breeds. The name "Lo-Chiang-Sze" literally translates to describe these physical characteristics, eventually being shortened to the more familiar "Lo-Sze."
During the Song Dynasty (960-1279 AD), the number of Lo-Sze in imperial palaces increased dramatically. Chinese emperors maintained elaborate breeding programs within the Forbidden City, where thousands of dogs lived under the care of dedicated eunuchs. These palace servants competed to produce the most remarkable specimens, leading to the development of eight distinct primary varieties of small, short-legged dogs. The Lo-Sze distinguished itself from other palace breeds through its short, smooth coat and characteristic tail that curled tightly over the back without feathering.
The breeding of Lo-Sze was strictly controlled by imperial decree. Only members of the imperial household were permitted to own these dogs, and any unauthorized possession was punishable by death. This exclusivity ensured that breeding remained within palace walls, where careful selection maintained the breed's distinctive characteristics. Female Lo-Sze were held in particularly high esteem, reportedly granted status equal to the emperor's wives during certain dynasties, including the reign of Emperor Ling To (168-190 AD).
The isolation and protected status of the Lo-Sze continued until the late 1500s and early 1600s, when China began establishing trade relationships with European countries including Portugal, Spain, Holland, and England. During this period, three types of small Chinese dogs made their way to Europe: the Fu Lin (ancestor of the Pekingese), the Shoku-Ken (predecessor of the Japanese Chin), and the Lo-Sze (progenitor of the modern Pug). European traders were fascinated by these exotic companions and began importing them to their home countries.
Once in Europe, the breeding focus gradually shifted to suit European preferences. By the early 1800s, European breeders favored longer-legged specimens with fawn and black coloration, leading to the development of the modern Pug breed as we know it today. This standardization, while creating a beloved and successful breed, meant that many of the original Lo-Sze characteristics were gradually lost. The varied colors, shorter legs, and longer muzzles that characterized the ancient breed became increasingly rare as European breed standards took precedence.
For nearly two centuries, the original Lo-Sze traits remained only in historical records and ancient artworks. The genetic diversity and unique characteristics that made these dogs so special to Chinese royalty seemed lost forever. However, in 1989, a dedicated breeder named Rebecca Manns began extensive research into the history of the Pug and its Chinese ancestors. Her investigation revealed the rich heritage of the Lo-Sze and highlighted how the original traits had been abandoned in favor of European preferences.
Motivated by her findings and dismayed that the original royal Lo-Sze had been altered to suit foreign tastes, Manns embarked on an ambitious project to reconstruct the ancient breed. Using her knowledge of historical breed characteristics and carefully selected breeding stock, she began working to recreate dogs that would embody the original Lo-Sze traits. Her efforts focused on producing dogs with the shorter legs, longer muzzles, varied colors, and gentle temperaments described in ancient Chinese texts.
The reconstruction project was both challenging and rewarding. Manns had to work with limited genetic material while trying to recreate traits that had been selectively bred out of the modern Pug population. She studied ancient Chinese art, consulted historical documents, and used genetic principles to guide her breeding decisions. The goal was not simply to create a variant of the Pug, but to honor the memory and characteristics of the original palace companions that had brought such joy to Chinese royalty.
In 1998, Manns' efforts achieved formal recognition when the International Rare Breed Dog Club Registry officially acknowledged the American Lo-Sze Pugg as a reconstructed breed. This recognition represented not just the success of a dedicated breeder, but the resurrection of a historic canine lineage that had been presumed lost. The trademark on the name "American Lo-Sze Pugg" ensures that only approved puppies meeting specific criteria can carry this designation, maintaining breed integrity and honoring the careful work of reconstruction.
Today, the Lo-Sze represents a unique achievement in dog breeding: the successful reconstruction of an ancient breed based on historical evidence and dedicated breeding practices. While the breed remains rare and is not yet recognized by major kennel clubs, its growing popularity among dog enthusiasts who appreciate both history and unique companion animals suggests a bright future. Each Lo-Sze carries within its genes the memory of imperial Chinese courts, representing a living link to one of the world's oldest companion dog traditions.
The story of the Lo-Sze also serves as a reminder of the importance of preserving breed diversity and honoring the historical significance of our canine companions. Through careful research and dedicated breeding, Rebecca Manns demonstrated that lost traits can sometimes be recovered and that ancient breeds can find new life in modern times. The Lo-Sze stands as a testament to both the enduring appeal of these ancient companions and the possibility of preserving canine heritage for future generations.
