The Yorkshire Terrier (often
shortened as Yorkie) is one of the smallest dog breeds of the terrier type
and indeed 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 silver-grey or a blonde
coat. Yorkshire terriers are playful and energetic dogs. They often
exhibit separation anxiety when left alone, which is a reason that some
owners keep two dogs.
