What dog breed is one of the oldest breeds of dog and has flourished since before 400 BCE.

The story behind the answer

Pugs are among the world’s oldest dog breeds, with origins in ancient China and records tracing them back to at least 400 BCE. Bred as lapdogs for Chinese emperors, they were prized for their charming flat faces and distinctive wrinkled foreheads. In contrast, Boxers and Bulldogs were developed in Europe much later (17th–19th centuries), and Chihuahuas, though ancient, are documented from pre-Columbian Mesoamerica—well after 400 BCE.

Fun memory hook: Pugs’ forehead wrinkles were said to resemble the Chinese character for “king” (王), reflecting their royal status. Carried along trade routes to Europe by Dutch merchants, they became favorites of royal courts, cementing their reputation as affectionate, dignified companions across centuries.
