Boston terriers are small, short-haired dogs that weigh up to 25 pounds. They have black and white or dark brown and white "tuxedo" coats. Some Boston terriers also have brindle patterns, or faint, multicolored stripes or patches, along some or all of their bodies.
During the late 19th century, a Boston native named Robert C. Hooper acquired a dog named Judge, who was half white English terrier and half English bulldog. Hooper and other dog breeders in his area bred Judge with other dogs, eventually creating the purebred Boston terrier in 1891.
Boston terriers are called "American Gentlemen" because of their well-groomed appearances and inherently gentle dispositions, according to the American Kennel Club. These types of dogs require minimal grooming and moderate exercise. They are easy to train and prefer to be near their owners at all times.
Boston terriers are prone to certain health conditions, including corneal ulcers, glaucoma, juvenile or late-onset cataracts, deafness, skin tumors and heart tumors. They are also known to experience breathing difficulties after overexerting themselves in hot or cold conditions. Drooling and snoring are also typical behaviors of dogs of this breed. Some Boston terriers fetuses have large heads that require veterinarian-supervised Caesarean deliveries.
