The Boston terrier is a compactly built, square-proportioned, short-backed, clean-cut dog. It should convey the impression of determination, strength, sturdiness, liveliness, and style, with a graceful carriage. It retains many of the attributes of its bulldog ancestors, but in a clean-cut package that makes a handy house companion. Its short fine coat, with distinctive markings, adds to its dapper appearance.

The Boston is devoted and sensitive to its owner’s wishes and moods. It is well-mannered indoors but saucy and playful (especially enjoying ball chasing) whenever the chance arises. Somewhat stubborn, it is nonetheless clever and learns readily. It is reserved with strangers, and some may be aggressive toward strange dogs. Some bark a lot.
