What health problems are common in the Boston Terrier?

The most common in the Boston Terrier are: Brachycephalic Obstructive Airway Syndrome (BOAS), Patellar Luxation, Early-Onset Juvenile Cataracts, Keratoconjunctivitis Sicca (Dry Eye), Congenital Sensorineural Deafness, Hemivertebrae.

1 to 4 years

Brachycephalic Obstructive Airway Syndrome (BOAS) [S15][S21]

A respiratory condition caused by compressed facial structures that obstruct airflow. It leads to noisy breathing, exercise intolerance, and severe heat sensitivity.

4 months to 1 year

Patellar Luxation [S15][S22][S23][S24]

A condition where the kneecap slips out of its normal groove. It causes sudden hopping, intermittent lameness, or abnormal gait.

Ask your vet about:

  • Manual stifle palpation
  • OFA patella evaluation
  • Orthopedic radiographs
8 weeks to 12 months

Early-Onset Juvenile Cataracts [S23][S24][S25]

An inherited clouding of the eye lens that obscures vision. It progresses rapidly and can lead to severe visual impairment.

Ask your vet about:

  • DNA test for HSF4 gene mutation
  • Annual CERF or CAER eye examination
2 to 7 years

Keratoconjunctivitis Sicca (Dry Eye) [S15][S26]

Inadequate tear production that leaves the surface of the eye dry and prone to irritation. It frequently results in corneal inflammation and secondary infections.

Ask your vet about:

  • Schirmer Tear Test
  • Fluorescein stain corneal test
3 to 6 weeks

Congenital Sensorineural Deafness [S27]

Inherited hearing loss linked to pigmentation patterns. It results in partial or complete lack of hearing present from early life.

Ask your vet about:

  • Brainstem Auditory Evoked Response (BAER) testing
3 to 10 months

Hemivertebrae [S25]

A congenital malformation producing wedge-shaped spinal vertebrae linked to the screw-tail trait. It can lead to spinal cord compression and mobility problems.

Ask your vet about:

  • Spinal radiographs
  • CT scan
  • MRI

What is a Boston Terrier's temperament like?

The Boston Terrier is a friendly, intelligent, and lively dog with a keen expression. It forms strong attachments to its human family and aims to please, though ancestral heritage brings occasional stubborn streaks.

[S5][S7][S8][S12]

How much exercise does a Boston Terrier need?

A Boston Terrier needs 30 to 60 minutes of exercise a day.

Daily needs are moderate and best fulfilled by split neighborhood walks, indoor play, and mental enrichment like snuffle mats or puzzle toys. Due to their flat facial structure, intense aerobic sessions and endurance runs are unsafe.

[S5][S13][S14][S15][S16]

How does a Boston Terrier handle heat and cold?

The flat facial anatomy hinders efficient cooling through panting, raising the risk of severe heat-related illness. A single, fine coat without an insulating undercoat makes the breed susceptible to chills in cold weather.

How much does a Boston Terrier shed, and how do you groom it?

Weekly brushing with a soft bristle brush or hound glove removes loose hairs. Facial wrinkles and eye borders require regular cleaning to prevent skin irritation, while baths are needed only every 4 to 6 weeks.

Is a Boston Terrier good with children and other pets?

Their compact size and infrequent nuisance barking make them well suited for apartment life. They generally coexist well with children and other domestic pets, though they may pursue small caged rodents due to rat-hunting ancestry.

Is a Boston Terrier easy to train?

The breed learns cues rapidly thanks to its high intelligence and eagerness to cooperate. Harsh reprimands cause them to shut down, so training succeeds best with positive reinforcement using praise and treats.

What does a Boston Terrier eat at each life stage?

  • PuppyPuppies require a small-breed puppy diet complete with animal protein, essential fatty acids including DHA, and balanced calcium and phosphorus to support steady bone growth without excess strain.
  • AdultAdults require balanced nutrition paired with strict portion control. Preventing excess body weight protects the airway from increased breathing strain and reduces stress on the knee joints.
  • SeniorSenior dogs benefit from formulations with lower caloric density to match a slowing metabolism, along with elevated dietary antioxidants and nutrients that assist joint mobility.

Where does the Boston Terrier come from?

The breed originated in Boston, Massachusetts, during the late 19th century through intentional crosses between the Bulldog and the extinct English White Terrier. A dog named Hooper's Judge founded the breed lineage after being bred to Burnett's Gyp around 1870. The club formed in 1891, the AKC admitted the breed in 1893 as the first US-made breed, and the FCI recognized it definitively in 1955.

Country of origin: United States.

Tips by life stage and weather

  • PuppyUse positive reinforcement with small treats and praise during training sessions because the young puppy shuts down under harsh correction.
  • PuppySupervise small children around the puppy to avoid rough handling and protect its prominent eyes from trauma.
  • AdultOffer daily mental stimulation using food puzzle toys or scent games indoors to satisfy energy needs without overexertion.
  • AdultWipe facial skin folds and eye margins regularly to remove moisture and prevent skin dermatitis.
  • SeniorSchedule regular checkups with your veterinarian to monitor stifle joints and corneal tear production as your dog ages.
  • SeniorProvide low-impact exercise split into short sessions to maintain joint comfort without stressing respiratory health.
  • Hot seasonWalk your dog exclusively during the coolest early morning or late evening hours to prevent fatal heat-related illness.
  • Hot seasonKeep outdoor physical activity brief and relocate games indoors to air-conditioned areas when temperatures and humidity climb.
  • Cold seasonDress your dog in a sweater or protective coat on chilly days to counteract its thin single coat and low body fat.
  • Cold seasonKeep cold-weather walks short to prevent rapid loss of body warmth.
  • Rainy seasonDry your dog thoroughly with a towel after wet walks, paying extra attention to facial folds to avoid moisture buildup.
  • Rainy seasonReplace outdoor exercise with leashed hallway walks or indoor fetch sessions when heavy storms occur.
