History & Origin
Originating in Boston, Massachusetts around 1870, the breed was created by crossing bulldogs with the white English terrier to produce a fierce pit fighter. Over time, selective breeding transformed the formidable fighter into a smaller, gentle, and affectionate companion. It was officially recognized by the AKC in 1893 as one of the first truly American breeds.
Interesting Facts
The Boston Terrier was the very first American-bred dog breed recognized by the AKC. It is also the official mascot of Boston University, and famous owners include several U.S. presidents such as Gerald Ford.
