What should I know about Boston Terriers?

By Sorin Vasiliu5 min read

At a glance

  • Size: 10–12 inches at the shoulder, 12–25 pounds (roughly 5.5–11 kg)
  • Lifespan: about 11–13 years
  • Energy: moderate, but it varies a lot between dogs
  • Coat: short and smooth, light shedding, a weekly brush
  • Main caution: a short muzzle, so heat and breathing come first

The AKC standard splits the breed into three weight classes for the show ring. They describe the breed's range, not a target for your dog. Ask your vet what a healthy weight looks like for yours.

LightestUnder 15Under 6.8
Middle15 to under 206.8 to 9
Heaviest20 to 259 to 11.3

Where Bostons come from

The AKC traces the breed to Judge, a Bulldog and white English Terrier cross bought by Robert C. Hooper of Boston in 1870. Breeders shrank that tougher type into a gentler companion, and the AKC recognized the breed in 1893. The Royal Kennel Club calls it the smallest of the bull breeds, the dogs with Bulldog blood. The American Staffordshire Terrier comes from similar Bulldog-and-terrier crosses, at a much larger size.

Temperament

The breed standard describes a friendly, lively, intelligent dog, nicknamed "the American Gentleman." VCA calls Bostons people-focused and generally good with children.

They want company. The AKC warns that a Boston left alone for long stretches can get frustrated and pick up unwanted habits.

Exercise and heat

Needs vary. For some Bostons, the AKC says a brisk walk or two a day is enough, while others need daily time to run and play. The Royal Kennel Club suggests up to an hour a day. A backyard on its own rarely counts, but a game of fetch does.

Heat is the real limit. Bostons are brachycephalic, or short-skulled, so panting often cools them less well and they overheat more easily. Breathing trouble tends to get worse in hot or humid weather. A few habits help:

  • Walk in the cooler parts of the day in summer
  • Slow down if breathing turns loud or labored
  • Keep fresh water out, and a cool room ready on hot days
  • Use a harness, not a neck collar, as VCA advises for dogs with airway trouble
  • In cold weather, add a coat and keep outings short, as the AKC suggests

Training and grooming

The AKC recommends early socialization and puppy classes, with treats as rewards. Many Bostons are sensitive, so gentle corrections followed by praise work best. VCA adds that they can turn stubborn without consistent guidance.

Grooming is light: a weekly brush, occasional baths and regular nail trims. VCA also suggests cleaning around the eyes and facial folds, and brushing the teeth.

Health watch-outs

These are the concerns breed clubs and vets list most often. Not every Boston will have them, and only your vet can judge your dog.

Watch-outWhy it comes upWhat you might notice
Brachycephalic airway syndromeNarrow nostrils and extra soft tissue crowd the airwaySnoring, snorting, noisy breathing, tiring fast
OverheatingPanting cools a short-faced dog less wellHeavy panting or distress on warm days
Eye problemsLarge, prominent eyes; corneal ulcers, dry eye, cataracts and glaucoma are all listedRedness, irritation, or a cloudy or sore-looking eye
Cherry eyeThe breed is listed as predisposed; in a large UK study, most cases were in young dogsA red, swollen lump in the inner corner of the eye
Patellar luxationThe kneecap slips out of its grooveA skip in the step, a back leg held up briefly
DeafnessThe breed club advises a hearing test for breeding dogsNot responding to sounds
Skin and allergiesAllergic skin disease, and facial folds that can get irritatedItching, scratching, red or sore skin in the folds

The Boston Terrier Club of America asks breeders to screen eyes, kneecaps and hearing, and to DNA-test for an early-onset hereditary cataract. VCA's list also includes heart disease, back disc problems and some cancers, so keep up with checkups.

VCA also notes that flat-faced dogs with airway trouble can have reflux, retching or vomiting. If your Boston seems gassy, swallowed air is likely the main source, and fast eating adds to it. Gas with diarrhea or weight loss needs a vet.

What to keep track of

Many of these problems start as small changes. A short written record helps you spot them and explain them at the vet, and how to keep a pet diary covers the habit.

  • Breathing and heat: snoring that gets louder, noisy breathing on walks, and how your dog copes on warm days
  • Eyes: a quick daily look for redness or irritation, as the AKC suggests, plus the date of any eye problem
  • Weight: a regular weigh-in, since extra weight makes airway problems worse
  • Vet visits: the AKC suggests a yearly wellness visit, so note what was checked and what the vet said
  • Vaccinations: what was given, when, and when the next dose is due

For the paperwork, organizing your vet records shows how to keep it all in one place.

Living with a Boston

Carra, the Boston Terrier behind this site, was born in May 2022 and was adopted from someone in Cluj. The AKC calls Bostons people-oriented and happy as apartment dogs, and the Royal Kennel Club lists the breed as suited to flat living.
