Yorkshire Terriers gained popularity during the Victorian era and were widely seen at dog shows. They became popular among royalty and the upper class, symbolizing wealth. Their popularity declined in the 1940s but was reignited by Smoky, a Yorkshire Terrier war dog from World War II. Smoky’s heroic actions brought attention back to the breed. Yorkshire Terriers are now one of the most popular toy-sized breeds in several countries, including the United States. They are recognized for their long hair that can touch the ground and their distinctive appearance. While most Yorkies have a black and tan coat, some may have a red-legged coat. Additionally, the Yorkshire Terrier has been involved in the creation of another breed, the Biewer Terrier. This breed emerged from the Yorkshire Terrier and is now recognized by the American Kennel Club. Overall, Yorkshire Terriers have a rich history and continue to be beloved companions to many.
