Pugs are considered one of the oldest breeds of dogs and have thrived since before 400 BCE. Originating in China, they were highly popular among Chinese emperors during the Han Dynasty. Pugs were then introduced to Europe via trading routes, particularly in the 16th century, and gained immense popularity in several European countries, including the Netherlands and England. Over the centuries, Pugs have maintained their distinctive features, including their compact size, wrinkled face, and curled tail, making them a beloved and recognizable breed that has stood the test of time.
