The Yorkshire Terrier (often shortened as Yorkie) is one of the smallest dog breeds of the 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. Most have a black and tan coat, but they are also known to have a silverish-grey or a blonde 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.
