The Yorkshire Terrier (also called a “Yorkie”) originated in Yorkshire (and the adjoining Lancashire), a region in northern England. In the mid-19th century, workers from Scotland came to Yorkshire in search of work and brought with them several different varieties of small terriers. Breeding of the Yorkshire Terrier was “principally accomplished by the people—mostly operatives in cotton and woolen mills—in the counties of Yorkshire and Lancashire.” Details are scarce. Mrs. A. Foster is quoted as saying in 1886, “If we consider that the mill operatives who originated the breed…were nearly all ignorant men, unaccustomed to imparting information for public use, we may see some reason why reliable facts have not been easily attained.”
The Yorkshire Terrier is a small dog breed of terrier type, developed in the 19th century in the county of Yorkshire, England, to catch rats in clothing mills, also used for rat-baiting. The defining features of the breed are its maximum size of 7 pounds (3.2 kg), but some Yorkies may exceed 7 pounds and grow to be up to 15 pounds. It has a gray, black, and tan coat. The breed is nicknamed Yorkie and is placed in the Toy Terrier section of the Terrier Group by the Fédération Cynologique Internationale and in the Toy Group or Companion Group by other kennel clubs, including the American Kennel Club, although all agree that the breed is a terrier. A popular companion dog, the Yorkshire Terrier has also been part of the development of other breeds, such as the Australian Silky Terrier.
