Boston Terrier Health Issues & Lifespan
Start here
Boston Terriers are cheerful, sturdy little dogs that usually live 11-15 years, but as a brachycephalic (flat-faced) breed they are prone to breathing trouble (BOAS) and eye problems. Their short muzzle and prominent eyes are the source of most of their signature health concerns.
What health problems are Boston Terriers prone to?
The Boston Terrier's compact, flat-faced build brings a fairly predictable set of issues:
- Brachycephalic obstructive airway syndrome (BOAS): narrow nostrils and a long soft palate make breathing harder, causing snorting, snoring, and heat intolerance.
- Eye conditions: their large, exposed eyes are prone to corneal ulcers, cherry eye, cataracts, and dry eye.
- Patellar luxation: the kneecap can slip out of place, causing a skipping gait.
- Brachycephalic-related dental crowding: a short jaw can crowd teeth and worsen dental disease.
- Hemivertebrae: malformed spinal bones (linked to the screw tail) can occasionally press on the spinal cord.
- Deafness: congenital hearing loss occurs in some lines, sometimes in one ear.
What early signs should Boston Terrier owners watch for?
Catching problems early is easier when you know what to look for:
- Noisy breathing, loud snoring, gagging, or struggling in heat or after exercise (airway signs)
- Squinting, pawing at the eye, redness, cloudiness, or a red mass in the corner of the eye
- A hind-leg skip or hop that comes and goes (possible luxating patella)
- Bad breath, tartar, or reluctance to chew (dental disease)
- Not responding to sounds or being startled easily (possible deafness)
Because their eyes sit so prominently, any eye change deserves a same-day vet call. Corneal ulcers can worsen fast.
How do you keep a Boston Terrier healthy?
Much of Boston care is about protecting the airway and eyes and keeping weight in check:
- Keep them cool: flat-faced dogs overheat easily. Avoid exercise in the heat, provide shade and water, and never leave them in a warm car.
- Use a harness, not a collar: this reduces pressure on the already-compromised airway.
- Stay lean: excess weight worsens breathing and joint strain. Boston Terriers gain weight easily.
- Protect the eyes: keep foreign matter away and address squinting quickly.
- Brush teeth regularly and keep up dental checkups.
Tracking weight and vet visits over time helps breed issues show up as trends. Logging each weigh-in and appointment in Tavi makes it easier to notice, say, gradual weight gain that is quietly making breathing harder.
How long do Boston Terriers live, and when should you see the vet?
Boston Terriers typically live 11 to 15 years. Many stay active and happy well into their senior years with good weight control and routine care.
See your vet urgently for any breathing crisis, collapse, or overheating, and promptly for eye changes, a red mass in the eye corner, persistent limping, or worsening snoring. Annual checkups (twice yearly for seniors) help catch heart, dental, and airway issues before they become serious.
Frequently asked questions
Do all Boston Terriers have breathing problems?
Not all, but as a brachycephalic breed they are at higher risk of brachycephalic obstructive airway syndrome (BOAS). Severity varies a lot between individuals. Some snore and snort but breathe fine, while others struggle in heat or after exercise. Keeping your dog lean, cool, and on a harness rather than a collar helps. Severe cases can be improved with corrective surgery.
Why do Boston Terriers have so many eye problems?
Their large, round, prominent eyes sit in shallow sockets with less protection, which makes them prone to corneal ulcers, dry eye, cherry eye, and cataracts. Any squinting, redness, cloudiness, or pawing at the eye should be checked the same day, since corneal injuries can worsen quickly. Routine eye exams help catch cataracts and dry eye early.
What is cherry eye in a Boston Terrier?
Cherry eye is a prolapse of the tear gland in the third eyelid, appearing as a red, fleshy lump in the inner corner of the eye. It is common in Boston Terriers and other flat-faced breeds. It is not usually painful at first but should be treated, ideally by surgically repositioning the gland rather than removing it, to preserve tear production.
How can I keep my Boston Terrier from overheating?
Exercise during the cooler parts of the day, always provide shade and fresh water, and never leave them in a parked car. Watch for heavy panting, drooling, bright red gums, and distress, which signal heat stress. Because their short muzzle makes cooling by panting less effective, flat-faced dogs need extra care in warm, humid weather.
