The Yorkshire Terrier (often shortened as Yorkie) is one of the smallest dog breed of terrier type, and of any dog breed. The breed developed during the 19th century in Yorkshire, England. Ideally its maximum size is 7 pounds (3.2 kg). A popular companion dog, the Yorkshire Terrier has also been part of the development of other breeds, such as the Silky Terrier. It has a grey, black and tan coat.

Yorkshire Terriers are very playful and energetic dogs. Many people who have a Yorkie as a pet have two, because they often have separation anxiety when left alone.

The ideal Yorkshire Terrier character or "personality" has been described by the Kennel Club as having a "carriage very upright feisty" and "conveying an important air".Though small, the Yorkshire Terrier is active, very protective, curious, and fond of attention. Mentally sound and emotionally secure ones should normally not show the soft submissive temperament seen in lap dogs,  although many exhibit this behaviour due to improper training.

Because of this, it is advised that a Yorkie would not be suitable for a home with typical young children. Instead, they make ideal companions for older families with many more reputable breeders routinely only homing to families with children older than about 10 years for the comfort of the dog, but more so for the benefit of the child.

Yorkshire Terriers are an easy dog breed to train. This results from their own nature to work without human assistance. They are naturally smart and quick to learn with many being food and/or praise motivated.

Because they were developed as a working breed, many need a lot of both physical and mental stimulation—with both long walks/runs but also indoor games and training to keep their mind busy. They are known for being yappy, but many have reported that a contented Yorkie is a quiet one—that will happily curl up on your knee in the evening. But they are all individuals, with some being much more laid back than others, and the breeder sho

uld ideally be able to advise on the needs and temperaments of their particular line. Yorkies are easily adaptable to all surroundings, travel well, and make suitable pets for many homes. Due to their small size, they require limited exercise but need daily interaction with people. They thrive on attention and love. Many are more timid around other dogs and prefer to stay close to their humans for comfort.
