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 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 or Companion 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.
For Yorkshire Terriers, importance is placed on coat colour, quality, and texture. The hair must be glossy, fine, straight, and silky. Traditionally the coat is grown out long and is parted down the middle of the back, but "must never impede movement."
A newborn Yorkshire Terrier puppy is born black with tan points on the muzzle, above the eyes, around the legs and feet and toes, the inside of the ears, and the underside of the tail. Occasionally yorkies are born with a white "star" on the chest or on one or more toes. Also, a few Yorkies are born with a red tint in their coat, but that is only when the parents also have this trait. It is also common to find white patch on one or more nails. These markings fade with age, and are usually gone within a few months.
