The Yorkshire Terrier, with his long flowing coat and graceful gait, is probably the most glamorous of the smaller (Toy-type) terrier breeds. In the 19th century, however, he weighed about fifteen pounds and had been originally developed to perform the less-than-glamorous but necessary job of controlling the rats in the coal mines and cotton mills of Yorkshire, England. The Yorkshire Terrier was recognized by the United Kennel Club in 1956.
