Boston Terrier Dog Breed Information
Also known as: Boston Bull, American Gentleman
A small, brachycephalic companion in a tuxedo-marked coat. Friendly, playful and apartment-friendly, with the heat sensitivity and breathing concerns common to flat-faced breeds. Despite the name, Dogs NZ classifies the Boston in Non Sporting, not Terriers.
A highly affectionate, highly trainable, great with young children dog. On the practical side: low grooming demands and minimal drool.
About the Boston Terrier.
The Boston Terrier is one of NZ’s most apartment-friendly small breeds and has been climbing the council registration rankings as more Kiwis move into shared-wall housing in central Auckland, Wellington and Christchurch. The personality is warm and quietly intelligent, the size suits a one-bedroom flat, and the bark is occasional rather than constant. The trade-off is brachycephalic conformation, less severe than the Pug or French Bulldog but still real, and any honest NZ buyer’s guide has to spell out the heat limits before quoting the puppy price.
Adults stand 23 to 38 cm at the shoulder and weigh 4.5 to 11.5 kg, with NZKC standards splitting the breed into three weight divisions. The smooth single coat is most often black and white in the tuxedo pattern that earned the breed its “American Gentleman” nickname, with brindle-and-white and seal-and-white also recognised. Lifespan sits at 11 to 13 years for a well-bred, lean dog with managed heat exposure.
Personality and behaviour
Boston Terriers are friendly with almost everyone: family, strangers, kids, other dogs. They are biddable, food motivated, and respond exceptionally well to short training sessions, more so than the French Bulldog or Pug. They retain a playful streak through life, with adult Bostons happy to chase a ball, play tug or work a snuffle mat in 10 to 15 minute bursts before settling onto the couch.
The breed is sociable rather than protective. A Boston will alert at the door but the default reaction to a stranger is enthusiasm, not suspicion. Most NZ Bostons are easy with other dogs and children, with patience that registered breeders typically point to as one of the breed’s defining traits. The compensating trait is intensity of attachment: Bostons bond hard to their household and tend to struggle with full workdays alone.
The trait that surprises new owners is the cleverness. A Boston will work out which cabinet contains the treats, which window catches the sun in the afternoon, and which family member hand-feeds when no one is watching. The breed is more trainable than the small flat-faced average and rewards owners who put short daily training sessions into the routine.
Energy is moderate, not low. A Boston will play hard in 10 to 15 minute bursts, then nap. The bark is occasional rather than constant. Snoring, snorting and reverse-sneezing at rest are normal for the breed; persistent loud breathing on a walk, blue gums or collapse all need same-day vet attention.
Care and exercise
Plan on around 45 minutes of structured exercise a day, split across two walks plus indoor play. The Boston is more aerobically capable than the Pug or Frenchie but still cannot pant efficiently in heat, and a single overheated walk on a 25-degree Auckland afternoon can put a Boston in the emergency vet at NZ$1,500 to NZ$4,000 for stabilisation. Walk before 9 am and after 6 pm December through February in the upper North Island.
The smooth coat sheds lightly year-round. A weekly brush with a rubber curry mitt keeps the loose hair contained. Wipe the facial wrinkles around the muzzle with a damp cloth twice a week to prevent fold dermatitis, more in summer when the folds get sweaty. The bulging eye sits close to the world and gets dust and grit; check eyes daily and rinse with a saline wipe if needed.
Diet matters more than the small size suggests. A 1 kg overweight Boston is the equivalent of 6 to 12 kg on a 60 kg human, and obesity worsens BOAS, joint disease and skin allergies. Measure portions, weigh the dog monthly, and treat training treats as part of the daily ration. Most adult Bostons eat 100 to 180 g of quality dry food a day depending on size, split into two meals.
Use a Y-front harness rather than a collar. The short neck makes tracheal pressure a real concern, and a Boston pulling on a flat collar can collapse on a hot day. Most NZ Boston households also keep a portable water bottle in the dog’s walk bag for warm-month walks.
Climate fit across New Zealand
The Boston handles NZ climate better than the Pug or Frenchie but is still a brachycephalic dog and cannot pant efficiently. Regional differences matter.
- Auckland and Northland. The hardest fit. Humid summers above 25 degrees regularly push Bostons into mild heat stress, with severe cases ending in emergency vet visits. Walk early or late only, ensure aircon or a tile floor for indoor cooling, and never leave a Boston in a parked car (interior temperature can hit 50 degrees within 10 minutes on a summer day). Beach walks at low tide in cool water are a strong NZ summer option for the breed.
- Wellington. A good fit. Cool summers, breezy days, and shorter periods of high heat. Wind and rain are no problem; the smooth coat dries fast. The hilly suburbs are workable but build distance gradually for puppies under 12 months.
- Christchurch and Canterbury. A strong year-round fit. Cold winters are easy on the breed (a small fleece coat helps in frost). Hot dry nor’westers in summer still require the early-walks rule. Dust and grass seed need a check after walks in long grass.
- Central Otago and Southland. Suits the breed. Cold weather is the easy half of the year for any flat-faced dog. Frost and snow are fine for short walks; dry the dog off afterwards and keep walks under 20 minutes when temperatures fall below freezing. Indoor warmth matters more than for a thicker-coated breed.
Where to find a Boston Terrier in New Zealand
Three reasonable paths.
- Registered NZKC breeders. The Dogs NZ breeders directory lists registered Boston Terrier breeders by region. Expect a 4 to 12 month waitlist and NZ$2,500 to NZ$4,500 for a registered puppy. Look for breeders who BOAS-grade their parents, score patellas, BAER-test puppies for hereditary deafness, DNA-test for juvenile hereditary cataract, and breed for a longer muzzle and more open nostril than the show extreme. Reputable breeders typically interview buyers carefully and place into long-term homes.
- Boston Terrier rescue. Boston Terrier Club of NZ rescue and small breed rescue networks occasionally take in surrendered adult Bostons. Adoption fees usually run NZ$400 to NZ$900.
- SPCA NZ. Boston and Boston-cross dogs appear in SPCA centres occasionally, often with limited backstory. Adoption includes desexing, vaccination, microchipping and parasite treatment, typically NZ$300 to NZ$700. The SPCA recommends meeting any flat-faced dog several times before committing because individual airway grades vary widely.
Avoid online listings advertising “rare” colours (blue, lilac, merle), breeders selling without BAER hearing tests or BOAS grading, and any source under 8 weeks old. The breed’s broad popularity has attracted volume breeders cutting corners on exactly the screens registered breeders perform.
Council registration is required by 12 weeks under the Dog Control Act. The DIA national dog database holds the record; your local council issues the tag and the annual fee.

What to ask the breeder.
Reputable NZKC breeders test for these conditions and share results without being prompted. If a breeder won't share screening results, that is itself an answer.
Common
5 conditionsBrachycephalic obstructive airway syndrome (BOAS)
Less severe on average than Pug or Frenchie but still significant. Severe cases need surgical correction at NZ$3,500 to NZ$8,000.
Heat stress and heatstroke
A flat-faced dog cannot pant efficiently. Real risk in NZ summers, especially Auckland and Northland.
Patellar luxation
Slipping kneecaps. Reputable NZKC breeders score parents.
Eye conditions (cherry eye, corneal ulcer, cataract, juvenile cataract)
The bulging eye sits close to the world. Juvenile hereditary cataract has a DNA test reputable breeders use.
Dystocia (difficult birth)
Most Boston Terrier litters are delivered by C-section because of the broad head and narrow hips.
Occasional
3 conditionsDeafness (congenital)
Linked to the white coat pattern. Reputable breeders BAER-test puppies before placement.
Hemivertebrae and spinal disease
The screw tail comes from a spinal malformation that can extend further along the spine.
Allergies and atopic dermatitis
An occasional condition in the Boston Terrier. Worth asking about and DNA testing where available.
The Boston Terrier in NZ.
- NZ popularity: ranked #28
- Popularity: A consistent presence in NZKC small-breed registrations and increasingly common in Auckland, Wellington and Christchurch apartments and townhouses. Popularity has risen with the wider trend toward small companion breeds in urban NZ.
- Typical price: NZ$2500–4500 from registered breeders
- Rescue availability: occasional
- NZ climate fit: Real heat limits in upper North Island summers. Brachycephalic dogs cannot pant efficiently. Avoid midday walks December through February in Auckland, Hamilton, Tauranga and Northland. The Boston handles cool wet weather well and suits Wellington and Christchurch year-round.
- Living space: Suits apartments and townhouses. Stairs are fine for adult Bostons but limit jumping off high furniture because of spinal load and the breed's predisposition to hemivertebrae.
Who the Boston Terrier is for.
Suits
- Apartment dwellers in Auckland, Wellington and Christchurch
