Pug

The Pug is one of the oldest living dog breeds, dating back to before 400 BC. The earliest known source of the Pug was in China, where they were kept among Buddhist monasteries. Later Prince William II's fondness of the breed made them very fashionable. Best described as a lot of dog in a small body, the Pug weighs between 13 and 20 pounds and stands at 10 to 14 inches. The breed is not very tolerant of hot or cold climates, so being inside is best for the Pug.
