Jemmy Shaw, also known as Jimmy Shaw, was one of the pioneer fanciers of the early dog show days, a promoter of dog fighting and rat-baiting contests and a breeder of Old English bulldogs, Bull Terriers, and Toy Terriers. According to the Sporting Chronicle Annual, Jem owned a black and tan Bull and Terrier named "Jacko", the world record holder for rat killing.
