Known as the "American gentleman," the Boston terrier is a dapper fellow. A cross between the English bulldog and English terrier, this dog's a popular family pet. If you live in a tight space, you won't need to worry about him taking up much room because he's a compact little dog.

Short and Spiffy

Whether you're talking about the lady or gentleman of the breed, the Boston terrier averages about 15 to 17 inches tall at the shoulder. His weight ranges between 10 and 25 pounds. For show purposes, the American Kennel Club, or AKC, divides his weight into three classes: under 15 pounds, 15 to 19 pounds and 20 to 25 pounds. The average weight for the Boston terrier is between 13 and 16 pounds. He's a short-backed and squarely-proportioned pup who sports a sturdy look.

Let's Play

Though he's a little dog, the Boston terrier is an enthusiastic playmate. He doesn't require excessive exercise, however he'll happily engage in some play, including a fun game of Frisbee. He's a quick learner, making him a good candidate for agility training. If he's a playmate for the kids, take care that they understand he's small and not as durable as a large dog may be, despite his sturdy profile. If it's just you and your Boston, he won't suffer if he doesn't have a yard to romp in or children to entertain him; a short walk outside is fine for him.

Time for Snuggles

The Boston terrier is very devoted to his family and enjoys cuddling and snuggling, easily accommodated by his diminutive size. He's particularly fond of settling in on your lap when it's movie night on the sofa or napping in bed with you. A social guy, he tends to get along with other pets well and after an excited, possibly barky, hello, he usually warms up to visitors.


Generally, the Boston terrier isn't a high-maintenance dog, but he does need the basics. That means he should have obedience training as well as daily exercise and social time with his people. He may enjoy playtime outside, but he's not made for living outdoors. His short, smooth coat needs weekly brushing to remove dead hair. He doesn't have major health concerns, but cataracts and patellar luxation are among the few sporadic health concerns with the breed. His flat face means you may hear snoring and snuffling, and occasionally more serious breathing issues. He has a lifespan of between 10 and 14 years.
