In China, the term "Pug" usually refers to the Pug, or Hovawart, breed. Because Pugs are relatively popular in China, "Pug" has become a nickname for the breed. Pugs are a medium-sized dog breed that originated in Germany. They usually have a thick outer coat of black, golden or brown and a soft inner coat. They are loyal, gentle and intelligent, and make great family pets and working dogs.
