The Chief Dog

Sinbad (c. 1936 - 30 December 1938) was a mixed-breed dog that was one of two animals to be classified as non-commissioned officers by an arm of the United States military, rather than property, prior to the enactment of regulations to prohibit such (the other being Sergeant Stubby USA, WWI) after being enlisted by the creative crew of USCGC Campbell. Prior to and after an official retirement, Sinbad was assigned the title of Chief Dog (abbreviated K9C), his rank being that of Chief Petty Officer.
