The dog (Canis familiaris or Canis lupus familiaris) is a domesticated descendant of the wolf. Also called the domestic dog, it is derived from extinct gray wolves, and the gray wolf is the dog's closest living relative. The dog was the first species to be domesticated by humans. Experts estimate that hunter-gatherers domesticated dogs more than 15,000 years ago, which was before the development of agriculture. Due to their long association with humans, dogs have expanded to a large number of domestic individuals and gained the ability to thrive on a starch-rich diet that would be inadequate for other canids.
The Russian Toy (also known as the Russian Toy Terrier, and in Russia as the Russkiy Toy , Russian: Русский той) is a very small breed of dog originally bred in Russia from the English Toy Terrier. There are two types of coats in the breed: smooth coat and long coat. The smooth-coated variety was previously known as the Russian Toy Terrier and long-coated as the Moscow Long-Haired Toy Terrier. Both were brought together under the same Russian Toy Terrier name in 1988 and the "Terrier" was dropped from the name when the breed was added in 2006 to the official list of breeds registered with the Fédération Cynologique Internationale and has been registered in the Foundation Stock Service of the American Kennel Club since 2008, allowed to compete in AKC companion events since 2010. The first official breed standard of the two varieties was written in 1966 in Russia.
The breed was nearly wiped out twice; first in the 1920s with the rise of Communism due to the toy dog's traditional link to the aristocracy and again in the 1990s with the influx of foreign breeds following the fall of the Iron Curtain. The smooth coat type is the older of the two, with the long coat type first appearing in 1958. (Full article...)
The Yukon Quest, formally the Yukon Quest 1,000-mile International Sled Dog Race, is a sled dog race scheduled every February since 1984 between Fairbanks, Alaska, and Whitehorse, Yukon, switching directions each year. Because of the harsh winter conditions, difficult trail, and the limited support that competitors are allowed, it is considered the "most difficult sled dog race in the world", or even the "toughest race in the world"—"even tougher, more selective and less attention-seeking than the Iditarod Trail Sled Dog Race." The originator envisioned it as "a race so rugged that only purists would participate."
In the competition, first run in 1984, a dog team leader (called a musher) and a team of 6 to 14 dogs race for 10 to 20 days. The course follows the route of the historic 1890s Klondike Gold Rush, mail delivery, and transportation routes between Fairbanks, Dawson City, and Whitehorse. Mushers pack up to 250 pounds (113 kg) of equipment and provisions for themselves and their dogs to survive between checkpoints. Each musher must rely on a single sled for the entire run, versus three in the Iditarod. (Full article...)
