Boston Terrier - Boston, Massachusetts

The Boston Terrier, nicknamed the "American Gentleman," originated in the 1870s as a cross between a bulldog and a white English Terrier. The resulting dog – the ancestor of all modern Boston Terriers – was named Judge, and was sold to a Boston man named William O’Brien. They’re the official dog of Massachusetts and the mascot of Boston University.
