The Yorkshire terrier originated in Yorkshire (and the adjoining Lancashire), a rugged 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." What is known is that the breed sprang from three different dogs, a male named Old Crab and a female named Kitty, and another female whose name is not known. The Paisley Terrier, a smaller version of the Skye Terrier that was bred for a beautiful long silky coat, also figured into the early dogs. Some authorities believed that the Maltese was used as well.
They were all originally bred from Scotch terriers (note: meaning dogs from Scotland, not today's Scottish Terrier) and shown as such...the name Yorkshire terrier was given to them on account of their being improved so much in Yorkshire." Yorkshire terriers were shown in a dog show category (class) at the time called "Rough and Broken-coated, Broken-haired Scotch and Yorkshire terriers". Hugh Dalziel, writing in 1878, says that "the classification of these dogs at shows and in the Kennel Club Stud Book is confusing and absurd" in lumping together these different types. But in the late 1860s, a popular Paisley type Yorkshire terrier showdog named Huddersfield Ben, owned by a woman living in Yorkshire, Mary Ann Foster, was seen at dog shows throughout Great Britain, and defined the breed type for the Yorkshire terrier.
