The Yorkshire Terrier, also called Yorkie, is perfect as companion and lap dog and the most popular Toy breed in the United States. The breed is approximately 100 years old and the first Yorkshire with today's standard appeared in a dog show in 1870.
It seems that many breeds from Scotland and England have contributed in the development of this breed. On the Scottish side, the contributors may be the Waterside Terrier, the Paisley Terrier and the now extinct Clydesdale.
On the English side, they are the Old English Black and Tan, the Dandie Dinmont Terriers and the Maltese.
