Question: Moscow Watchdog and Teddy Roosevelt Terrier, are a breed of what?

Context paragraphs:
Moscow Watchdog: 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.

Teddy Roosevelt Terrier: 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: 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."

American Russell Terrier Club: 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 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.

In Britain this breed has also been used as a war dog, guide dog and police dog.
