Boston Terrier Health Issues: Breathing and Eyes

A Boston Terrier’s short face and large, prominent eyes shape most of its health care: the airway is narrowed, heat is risky, and the eyes are easy to injure. Mast cell tumours and allergies round out the list. This guide is general information, not veterinary advice.

The short answer

Keep a Boston lean and cool, walk it on a harness and avoid exercise in heat. Treat a squinting, cloudy or painful eye as urgent. Get every new lump sampled. See a vet for itchy skin or ear trouble. Remind your vet before anaesthesia that your dog is flat-faced. Price pet insurance in your first week.

Breathing and heat

The Boston Terrier is on VCA Animal Hospitals’ list of flat-faced breeds with brachycephalic airway syndrome. Snoring, noisy breathing and tiring quickly are common, and Bostons overheat more easily than long-nosed dogs.

Keep the dog lean, exercise in the cool part of the day, use a harness and stop at heavy panting. Blue-tinged gums or collapse is an emergency. Airway surgery helps some dogs and works better earlier. Remind your vet before sedation or anaesthesia that your dog is flat-faced.

Eyes

Large, prominent eyes are easily scratched. Squinting, tearing, pawing at the face or a cloudy spot can mean a corneal ulcer and needs a vet the same day.

The Boston is also on VCA’s list of breeds associated with glaucoma. A red, painful, cloudy or bulging eye is an emergency, because vision can be lost within hours.

Lumps and skin

Boston Terriers are on VCA’s list of breeds prone to mast cell tumours, which can look like an insect bite or a harmless bump. Every new lump deserves a quick needle sample.

Itching, licking, red skin and recurring ear infections are often allergies, which VCA explains are managed rather than cured. The short facial wrinkle can also trap moisture; wipe and dry it during grooming.

The first vet visit after adoption

Ask for an airway and breathing check, an eye exam, a skin and lump check, an ear check, a body condition score and baseline bloodwork. Note in the file that the dog is flat-faced. Bring the rescue’s records.

Price pet insurance the same week. Every Canadian provider excludes conditions documented before enrolment, and eye emergencies and airway surgery are common costs in short-nosed breeds.

Frequently asked questions

What are the most common Boston Terrier health issues?

Short-nose breathing problems, eye injuries and glaucoma, mast cell tumours, and allergies with itchy skin and ear infections.

Why does my Boston Terrier snore?

The short face narrows the airway. Keep the dog lean and cool, use a harness and ask your vet whether the airway needs attention.

My Boston is squinting. Is it urgent?

Yes, see a vet the same day. Prominent eyes are easy to scratch, and a red, painful, bulging eye can also mean glaucoma, which is an emergency.

Should I worry about lumps on my Boston Terrier?

Have each new lump sampled. Bostons are prone to mast cell tumours, which can look harmless, and early removal is often curative.

Can Boston Terriers handle hot weather?

Poorly. Exercise them in the coolest part of the day, give shade and water, and stop at heavy panting.

Should I get pet insurance for a rescue Boston Terrier?

It is worth pricing in your first week. Canadian pet insurance excludes conditions documented before enrolment, and eye and airway care are common costs.
