Doge is a slang term for “dog” that is primarily associated with pictures of Shiba Inus (nicknamed “Shibe”) and internal monologue captions on Tumblr. These photos may be photoshopped to change the dog’s face or captioned with interior monologues in Comic Sans font.
The Bouvier des Flandres is a herding dog breed originating in Flanders. They were originally used for general farm work including cattle droving, sheep herding, and cart pulling, and nowadays as guard dogs and police dogs, as well as being kept as pets. The French name of the breed means, literally, "Cow Herder of Flanders", referring to the Flemish origin of the breed. Other names for the breed are Toucheur de Boeuf (cattle driver), Vlaamse Koehond (Flemish cow dog), and Vuilbaard (dirty beard).
Duchess is the name of Malory Archer's dog (an Afghan hound). Malory showed great affection towards Duchess, much more than she has ever shown her son, Sterling. She has many pictures of Duchess on the walls of her apartment and office, and even a creepy picture of her lying naked with the dog in bed (a satire of John Lennon and Yoko Ono's Rolling Stone cover picture). Malory claimed Duchess to be a smart dog, despite the fact Duchess in fact died from eating a piece of chocolate from the trash.
