Similar dogs are the Smooth and Wire Fox Terriers, originally developed to flush out foxes for hunters in England (but now primarily kept for conformation showing and as pets), and the Jack Russell Terrier, used for ratting. Fox Terriers and feists are often predominantly white so as to be visible to hunters. Many other variants of this type exist, such as the Russell Terrier, Parson Russell Terrier and Rat Terrier, with many locally developed purebred dog breeds. The original fox terrier type was documented in England in the 18th century.
