The Yorkshire Terrier was developed during the mid-nineteenth century in the industrial counties of Yorkshire and Lancashire in northern England. The breed did not emerge from aristocratic kennels but rather from the working-class communities that powered the textile mills and coal mines of the region. Scottish weavers migrating south for factory work brought several small terrier types with them, and these dogs were crossed with local terriers over several generations to produce a compact, keen ratter well suited to the cramped conditions of mills and mine shafts.
Among the breeds believed to have contributed to the Yorkshire Terrier's foundation stock are the Clydesdale Terrier, the Paisley Terrier, the Skye Terrier, and the now-extinct English Black and Tan Toy Terrier. Early specimens were considerably larger than today's Yorkies, often weighing twelve pounds or more, and their coats, while long, were coarser than the silky texture modern fanciers prize. Selective breeding throughout the 1860s and 1870s refined the breed's size downward and its coat quality upward.
The breed was initially exhibited under a variety of names, including Broken-Haired Scotch Terrier and Halifax Fancy Terrier. It was not until 1870 that a journalist named Angus Sutherland proposed the name Yorkshire Terrier, arguing that the breed had been so thoroughly improved in Yorkshire that the county deserved naming credit. The Kennel Club of England accepted the name, and the breed was formally recognized in 1886.
A dog named Huddersfield Ben, born in 1865 and owned by Mary Ann Foster of Bradford, is widely regarded as the father of the modern Yorkshire Terrier. Ben won over seventy prizes in ratting contests and dog shows alike, establishing the type that breeders would follow for decades. His influence on the breed was so profound that nearly every modern Yorkie pedigree traces back to him in some fashion.
