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) and its 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 orCompanion Group by other kennel clubs, 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.
As a show dog in all the glory of his full coat, he draws the eye like a magnet. When he is kept purely as a pet, his coat is unlikely to achieve such magnificence, as the time required for proper care is rarely available. In either walk of life, he is well aware of his importance, and displays this in his carriage and bearing.
