The English Toy Terrier of today, was known as the Miniature Black & Tan Terrier up to the 1960’s, and can be traced back to the black & tan terriers recorded in the 16th century. In England during the 1800’s these terriers were very much in demand as ratters due to the increasing rat population brought about by the advancement of the industrial revolution. They were carried by gentlemen in their pockets on hunts and sent to ground as necessary to flush out foxes etc.
In 1830 the gamekeepers of the time, established a hierarchy, which designated the various colors as those of official game. The official game was that of the now extinct Yorkshire, plus other assorted colors that characterized the shorter coat, the longer hair etc.
