About the Boston Terrier
The Boston Terrier is a small, strong, well-muscled dog with a short, square muzzle, erect ears and large, round eyes set wide apart. Its smart brindle or black coat with white markings has earned it the nickname "the American Gentleman". It is a lively, affectionate dog that loves human company and joins in with everything.

The breed takes its name from the city of Boston in the USA, where it was developed. Its founding father is said to be a dog called Hooper's Judge, born in Liverpool, a cross between a Bulldog and an English White Terrier, who was exported to America. The first breed club was founded in Boston in the 1890s, and by the 1950s the Boston was the most popular breed in the USA.
It is the smallest of the bull breeds. Despite the name, it is in the Utility group rather than the Terrier group, and it does not behave much like a terrier.
Boston Terriers are brachycephalic, or flat-faced. PDSA warns that they are likely to suffer serious health and welfare problems because of their shape, including severe breathing difficulties and eye problems, and it strongly recommends that owners consider a healthier breed, crossbreed or mongrel.
Boston Terrier temperament
Boston Terriers are typically affectionate, fun-loving and outgoing, and they usually get on well with everyone if socialised as puppies. They can be determined and strong-willed, and they love to play.
They are much happier at home with their owners than getting into mischief, and they like to go everywhere with their family. They are generally quiet dogs, although they will alert you to visitors. Many snore because of the shape of their muzzle.
Size and appearance
Boston Terriers are small dogs. Adults typically stand 38–43 cm at the shoulder and weigh around 7–11 kg.
The coat is short and smooth. Breed standard colours are black and white, brindle and white, mahogany brindle and white, seal and white, and seal brindle and white. Blue and white and red and white are non-breed-standard colours, and the Royal Kennel Club advises choosing a dog that fits the breed standard.
How much exercise does a Boston Terrier need?
Up to an hour of exercise a day is usually enough. Bostons do not crave long walks, but they enjoy games and like to go everywhere with you.
They are prone to overheating, so never exercise them in the heat of the day. A Boston can live in a small home or flat, as long as it has access to the outdoors for exercise and toilet breaks.
Training a Boston Terrier
Boston Terriers respond well to training and enjoy the mental stimulation it brings. Many are good at learning tricks.
- Use reward-based techniques and start socialising your puppy early.
- Teach your Boston to walk on a harness and lead.
- Practise a reliable recall.
- Teach them to cope with being left alone occasionally.
Boston Terrier grooming
The short coat is easy to look after. A once-a-week groom with a grooming mitt removes dead hair and keeps the coat in good condition. Bostons are a clean breed without a strong doggy smell. Skin folds around the face can trap warmth and moisture, so keep an eye on them.
Living with a Boston Terrier
Boston Terriers are usually good with children and love to join in family games. They can be boisterous, though, and their prominent eyes are easily injured, so games should never get too rough. They are often best with sensible, older children. Whatever the breed, dogs and young children should never be left alone together, and an adult should supervise every interaction.
Children
Usually better with older, calmer children.

Usually sociable with other dogs.

Boston Terrier health
Not yet reviewed by a vet. This is general information, not veterinary advice: speak to your vet about your own dog’s health.
The Boston Terrier's flat face and body shape put it at risk of a number of health problems. The Royal Kennel Club places it in Breed Watch Category 2 and notes conformational concerns. Not every Boston will have these problems, but if you are thinking of buying a puppy it is important to take extra care and ask about the parents' health testing.
Brachycephalic obstructive airway syndrome (BOAS)
Excess soft tissue in the nose and throat, narrow nostrils and an elongated soft palate can obstruct breathing, causing noisy breathing, heavy panting, reduced ability to exercise or even severe respiratory distress. The Royal Kennel Club recognised a Respiratory Function Grading test for the breed in August 2026, to become part of best practice from January 2027.
Eye problems
Prominent eyes are at higher risk of injury and ulcers. Dry eye (keratoconjunctivitis sicca) and cherry eye, where the third eyelid gland pops up in the corner of the eye, are also seen. The Royal Kennel Club recommends eye testing under the BVA/KC/ISDS Eye Scheme.
Hereditary cataracts
Clouding of the lens of the eye, which can result in blindness. A DNA test (HC-HSF4) is available and recommended as best practice.
Skin fold problems
Folds of skin around the face create a warm, moist environment where bacteria and yeast can grow, leading to infection and itching. Atopy, an allergy that causes itching and skin damage, is also seen.
Dental problems
A shortened jaw with the same number of teeth can cause overcrowding and dental and gum problems.
Patellar luxation
The kneecaps can slip temporarily out of place.
Hemivertebrae
Deformities of the spinal bones that can press on the spinal cord, causing weakness, loss of hind-leg function and incontinence.
Cushing's syndrome
A hormonal disorder in which the body produces too much cortisol.
Difficulty giving birth
Boston Terriers have large shoulders compared with their smaller hindquarters and pelvis, so females often have problems giving birth naturally and frequently need a caesarean section.
What health checks should you ask about?
Responsible breeders and rescues are happy to talk about health, and any pressure to decide quickly is a reason to walk away. Before taking a Boston Terrier home, it is reasonable to ask about:
- Health testing of the parents. Ask which health tests the parents have had for conditions known in the breed, and to see the results.
- Veterinary and vaccination records. Puppies should have had a first vaccination and a vet check, with records you can take home.
- Microchip information. In England, Scotland and Wales puppies must be microchipped and registered by eight weeks old. Ask who the chip is registered to and how the transfer works.
- Registration paperwork. Registration papers, where they apply, record pedigree. They do not by themselves prove health or how a puppy was raised.
How much does a Boston Terrier cost to own?
There are two costs: bringing a Boston Terrier home, and looking after one well. Puppy prices depend on the breeder, health testing and demand; the adverts below show what sellers are asking today.
Ongoing costs are the ones new owners most often underestimate: food, insurance (which usually rises with age), routine vet care, vaccinations and parasite treatment, dental care, grooming, training, bedding and equipment, and boarding or a sitter for holidays. Budget for the whole of the dog’s life, typically from 10 years, not just the first year.
Buying a Boston Terrier
If you have decided the Boston Terrier suits your life, take the same care choosing where your dog comes from. Meet the puppy in person, see it with its mother, and look at how the litter is raised.
- Check who you are dealing with: every Mypetzilla advert shows the seller type and what we have checked.
- Ask about health testing, vaccinations and the microchip before you commit.
- Take your time. Do not be rushed by deposits or "last one left" stories.
- Meet in person before paying anything, and keep conversations on Mypetzilla.
Adopting a Boston Terrier
Boston Terriers do come up for adoption, through rescue organisations, breed rescues and private rehoming, often because an owner’s circumstances have changed rather than any fault of the dog. An adult dog arrives as a known quantity: its size, coat and character are already on show.
Rescues will usually talk you through the dog’s history, any medical care, and the home it needs, including children, other animals and time alone. Be honest about your circumstances: a good rescue would rather place a dog once, well.
