In the mid-to-late nineteenth century when Scottish weavers were forced out of work due to the industrial revolution, they found their way to northern England in the hope of supporting their families. When they left for England they brought their dogs with them. The Yorkshire Terrier that we know today evolved from this breed, with many believing that the bloodlines of Paisley and Clydesdale Terriers were also added to the mix.
The Yorkshire Terrier was used as a form of vermin control, since the areas where they lived were commonly infested. In 1865, the breed was given the official name of the Yorkshire Terrier and was introduced to the United States in 1872. Just six years later, in 1878, the Yorkshire Terrier was recognized by the American Kennel Club. However, the breed that was recognized in 1878 is completely unlike the Yorkshire terrier of today.
Selective breeding has reduced the average weight of the breed from thirty pounds to less than ten pounds. Today's Yorkshire Terriers are now miniature versions of their ancestors.
