The Yorkshire terrier is descended from the Waterside Terrier and was brought to Yorkshire, England, in the mid-19th century by weavers from Scotland. The earliest record of a Yorkshire terrier born in the United States dates to 1872. Dog breeders developed the Silky terrier in the early 1900s in Australia from crossing native Australian Terriers with imported Yorkshire Terriers. It was originally known as the Sydney Silky Terrier.
