The Boston Terrier was developed in Boston in the late 1800s from bulldog and terrier crosses, and it was among the first American breeds the AKC recognized, in 1893. Early dogs were heavier and more terrier-like. Over time the breed became the compact, short-faced companion known for its tuxedo-like markings and large round eyes. Adults typically weigh 12 to 25 pounds.
Many Bostons are friendly, lively and affectionate, happy to play one minute and burrow under a blanket the next. Their size and moderate exercise needs suit many homes, though some are stubborn or excitable. The short muzzle brings trade-offs such as snoring, breathing trouble and heat sensitivity, and the prominent eyes injure easily, which makes summer care a daily job on the Gulf Coast.
