Question: Moscow Watchdog and Teddy Roosevelt Terrier, are a breed of what?
Context: Moscow Watchdog (Russian: московская сторожевая ) is a breed of dog that was bred in the Soviet Union.  It descends from crosses between the St. Bernard, Caucasian Shepherd, and Russian Spotted Hound breeds.  It contains the physical size, attractiveness and intelligence of a St. Bernard and the awareness and assertive traits of a Caucasian Ovtcharka. The Teddy Roosevelt Terrier is a small to medium-sized American hunting terrier.  Lower-set with shorter legs, more muscular, and heavier bone density than its cousin the American Rat Terrier.  There is much diversity in the history of the Teddy Roosevelt Terrier breed and it shares a common early history with the American Rat Terrier, Fox Paulistinha and Tenterfield Terrier.  It is said the Rat Terrier background stems from the terriers or other dogs that were brought over by early English and other working class immigrants.  Since the breed was a farm, hunting and utility dog there was little to no planned breeding other than breeding dogs with agreeable traits to each other in order to produce the desired work ethic in the dog.  It is assumed that the Feist (dog), Bull Terrier, Smooth Fox Terrier, Manchester Terrier, Whippet, Italian Greyhound, the now extinct English White Terrier, Turnspit dog and or Wry Legged Terrier all share in the Teddy Roosevelt Terrier's ancestry.  These early Ratting Terriers were then most likely bred to the Beagle or Beagle cross bred dogs (for increased scenting ability) and other dogs.  Maximizing the influences from these various breeds provides the modern Teddy Roosevelt Terrier with a keen sense of awareness and prey drive, an acute sense of smell and a very high intellect.  Although they tend to be aloof with strangers they are devoted companion dogs with a strong desire to please and be near their owners side at all times. Holt Collier (c. 1848 – August 1, 1936) was a noted African-American bear hunter and sportsman.  While leading a hunt for U.S. President Teddy Roosevelt in November 1902, Collier unwittingly set the stage for the event that originated Roosevelt's nickname, "Teddy Bear." Captains Courageous is an 1897 novel, by Rudyard Kipling, that follows the adventures of fifteen-year-old Harvey Cheyne Jr., the spoiled son of a railroad tycoon, after he is saved from drowning by a Portuguese fisherman in the north Atlantic.  The novel originally appeared as a serialisation in "McClure's", beginning with the November 1896 edition.  In 1900, in his essay “What We Can Expect of the American Boy,” Teddy Roosevelt extolled the book and praised Kipling for describing “in the liveliest way just what a boy should be and do.” The American Russell Terrier Club (formerly named the English Jack Russell Terrier Club), founded by JoAnn Stoll in 1995, was the first registry in the United States to maintain the Russell Terrier as a separate breed from the Parson Russell Terrier.  The American Jack Russell Terrier Club is affiliated with both the United Kennel Club and the American Kennel Club.  The purpose of the early founders was to establish a registry for the perpetuation and development of the Russell Terrier as a pure strain of working Jack Russell Terrier keeping their blood and type pure within the registry to works towards Kennel Club recognition as an official breed in the US.  On January 1, 2001, the United Kennel Club recognized the Russell Terrier as an official breed, designating only the stock from the American Russell Terrier Club as Foundation stock for the UKC Russell Terrier.  In 2004 the American Russell Terrier Club submitted an official request to include the American Russell Terrier Club stock into the AKC FSS Program to work towards becoming an official breed under the perimeters.  On December 8, 2004, the AKC officially accepted the Russell Terrier. The Airedale Terrier (often shortened to "Airedale"), also called Bingley Terrier and Waterside Terrier, is a dog breed of the terrier type that originated in the valley ("dale") of the River Aire, in the West Riding of Yorkshire, England.  It is traditionally called the "King of Terriers" because it is the largest of the terrier breeds.  The Airedale was bred from the Old English Black and Tan Terrier (now extinct), the Bull Terrier, the Otterhound and probably some other Terrier breeds, originally to serve as an all around working farm dog.  In Britain this breed has also been used as a war dog, guide dog and police dog.  In the United States, this breed has been used to hunt big game, upland birds, and water fowl, and serve in many other working capacities. Thomas Hannah was an architect in Pittsburgh and Philadelphia in the United States.  He is credited with designing the Saint Nicholas Greek Orthodox Cathedral.  He also designed the Western Theological Seminary in Pittsburgh.  He also designed Midtown Towers, originally known as the Keenan Building and built in 1907. It was built for Colonel Thomas J. Keenan owner and founder of the "Penny Press" that became "Pittsburgh Press" The building may have been modeled after the Spreckel Building/ Call Building (1898) of San Francisco.  It is decorated with visages of 10 notables associated with Pittsburgh and Pennsylvania, including then-mayor George Guthrie and then-governor Edwin Stuart, in addition to George Washington and Teddy Roosevelt.  The dome was once capped with the figure of an eagle in flight. The Russian Toy (also known as the Russian Toy Terrier, and in Russia as the Russkiy Toy, Toychik,Russian: Русский той, Тойчик ) is a very small breed of dog originally bred in Russia from the English Toy Terrier which is known today as the Manchester 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. Terrier Group is the name of a breed Group of dogs, used by kennel clubs to classify a defined collection of dog breeds.  In general, a "Terrier Group" includes one particular type of dog, the Terrier, although other types may be included in a kennel club's "Terrier Group".  Most major English-language kennel clubs include a "Terrier Group" although different kennel clubs may not include the same breeds in their "Terrier Group".  The international kennel club association, the Fédération Cynologique Internationale, includes Terriers in Group 3 "Terrier", which is then further broken down into four "Sections" based on the type of terrier and breed history.
