Yorkshire terriers are a long-haired toy terrier whose blue and tan coat is parted on the face and from the base of the skull to the end of the tail and hangs evenly and quite straight down each side of body. The body is neat, compact and well proportioned. The dog's high head carriage and confident manner should give the appearance of vigor and self importance.

The ultra long, fine, silky coat parts along the spine and falls straight down on either side. It is steal blue on the body and tail, and tan elsewhere. Puppies are usually black & tan. The tail is usually docked to half its length. If the dogs are not for showing, the owners usually go for the shaggy look. The Yorkie has a flat head, medium-sized length muzzle, a black nose, and regular teeth. The eyes are extremely vivacious and the ears are v-shaped, erect or semi-erect. The tail is docked to medium-length and is carried level with its back. Its limbs are straight with round feet and black nails. The hair on the Yorkshire Terriers head is so abundant that it is almost always necessary to gather it in a band to keep from going into the dog's food bowl and to give the animal maximum visibility. Some owners choose to trim the hair on top of the head.
