The term “running dog” is a Chinese pejorative that refers to someone who curries favour with a more powerful, often antagonistic, force. The term is frequently used in Chinese Communist Party (CCP) propaganda, especially during the Mao Zedong era, to incite national zealotry to fight against the Western democracies.
