Jemmy Elton Shaw (1815 – 1885), also known as Jimmy Shaw and James Shaw, was a 19th-century pioneer and fancier of the early dog show days, a promoter of dog fighting and rat-baiting contests, a breeder of Old English bulldogs, bull terriers and toy terriers and a contributor in the development of fancy rats.
[1] According to the Sporting Chronicle Annual, Jem owned a black-and-tan bull and terrier named "Jacko", the world record holder for rat killing.
Shaw owned Tiny the Wonder, an English Toy Terrier (Black & Tan), famous in the City of London in the mid-19th century for being able to kill 200 rats in an hour in London's rat-baiting pits.
[2] In the mid-1800s, Shaw was the landlord of the Blue Anchor Tavern, now the Artillery Arms,[3] located at 102 Bunhill Row, St. Luke's, London Borough of Islington.
Between the 1840s and 1860s Jemmy Shaw and Jack Black bred and sold many different colours of fancy rats and their work aided in the establishment of them as pets.
