While serving as the minister to France (1784-89), Thomas Jefferson became aware of the writings of Georges-Louis Leclerc, the French naturalist who wrote that the Briard sheepdog was the finest dog he knew because of its intelligence and fine character. Jefferson searched for a dog of this breed and bought one which he named Buzzy. During the ocean voyage back to the United States, Buzzy gave birth to two pups, so Jefferson arrived with not one but three Briards. This was the beginning of what is known as the Briard Bergere line in the United States.
Despite its name, the Black Russian Terrier is not a true terrier: it is believed that about seventeen breeds were used in its development, including the Airedale, the Giant Schnauzer, the Rottweiler, the Newfoundland, the Caucasian Ovtcharka and other breeds.
Shortly after the resolution of the Cuban Missile Crisis, Khrushchev arrived at the White House with a little white dog named Pushinka (meaning "fluffy" in Russian). She came with a passport that identified her as a "nonbreed" but specified that her mother was Strelka, the first dog sent into space by the Russians. Pushinka was an instant hit with the Kennedy family but because of the Cold War, Pushinka was taken to Walter Reed Army Medical Center to be examined before she was permitted to settle into her new home. Officials wanted to be certain the dog was not bugged with any hidden listening devices, microphones, bombs, or germs.
