The breed universally recognized as the Boston Terrier carries several names and nicknames reflecting its rich American heritage and distinctive characteristics. The official designation Boston Terrier references the breed's city of origin, Boston, Massachusetts, where this uniquely American breed was developed during the late 19th century. This name has remained consistent since the breed's formal recognition, providing clear identification while honoring the city instrumental in the breed's creation and early promotion. The geographic reference distinguishes this breed from other terrier types while celebrating its status as one of the few breeds originating in the United States.
The American Gentleman stands as the breed's most beloved and widely recognized nickname, earned through the Boston Terrier's distinctive tuxedo-like coat markings and refined, courteous temperament. This affectionate designation appeared early in the breed's history, reflecting admirers' recognition that these dogs possessed both elegant appearance and gentle manners befitting gentlemanly behavior. The nickname emphasizes the breed's combination of distinguished looks with gracious temperament, creating an image of canine sophistication and refinement. This moniker has become so associated with the breed that many people recognize it immediately, even if they've forgotten the formal breed name. The American Gentleman designation also reinforces the breed's status as a uniquely American creation, distinguishing it from European terrier breeds.
Boxwood appears as an alternate name for the Boston Terrier, though this designation sees far less common usage than other breed names and nicknames. The origin and reasoning behind this particular name remain somewhat obscure, with various theories proposed by breed historians and enthusiasts. Some suggest the name references the compact, dense, sturdy nature of boxwood shrubs, drawing parallels to the breed's compact build and hardy constitution. The boxwood plant's association with formal gardens and refined landscapes might also connect to the breed's gentleman image and cultivated appearance. However, Boxwood never achieved widespread adoption as a breed name, remaining a curiosity in breed nomenclature rather than a commonly recognized designation. Most modern enthusiasts and breed documentation favor Boston Terrier or American Gentleman over this less familiar alternative.
Early in the breed's development, before formal recognition and standardization, these dogs were called Roundheads, referencing their distinctive round skull shape. This descriptive name appeared frequently in early breeding records and discussions among fanciers working to establish and refine the new breed. As the dogs' appearance became more standardized and their characteristics better defined, this informal designation gave way to more formal nomenclature. However, Roundheads remains historically significant as evidence of the breed's evolution from early foundation stock to the modern Boston Terrier, appearing in historical documents and breed histories as a reminder of the developmental period before official recognition.
The designation Boston Bull and variations including Boston Bull Terrier appeared during the breed's early years, reflecting its bulldog ancestry and bull-baiting origins. These names emphasized the breed's connection to both bulldog and terrier heritage, acknowledging the crosses that created the foundation stock. The American Bull Terrier Club, formed in 1889 as the first breed club, initially used this type of naming. However, confusion with other breeds bearing similar names, particularly English Bull Terriers, led to the change. By 1891, breed enthusiasts had renamed their organization the Boston Terrier Club of America, and the breed name was officially changed to Boston Terrier when the American Kennel Club granted recognition in 1893. This name change eliminated confusion while maintaining clear reference to the breed's geographic origins.
Some enthusiasts and breeders occasionally reference the breed simply as Bostons, using the shortened form in casual conversation and informal contexts. This abbreviated designation appears frequently in breed-specific publications, social media discussions, and conversations among experienced owners and breeders who find the full name unnecessarily formal for everyday use. While Bostons lacks official status as an alternate breed name, it functions effectively as convenient shorthand within communities familiar with the breed. This informal usage demonstrates the affection owners feel toward these dogs, creating a familiar, friendly designation suggesting close relationship rather than formal distance.
