10 Key Things to Know About Boston Terriers Before Buying

The Boston terrier is often mistaken for the French bulldog, but knowledgeable owners quickly spot the differences. This distinctive, small breed belongs to the Kennel Club's utility dog group and makes a popular companion for those who want an affectionate small dog with a unique personality.

Before you decide to bring a Boston terrier into your home, it's vital to understand what this breed entails in terms of health, exercise, cost, and temperament. Below are ten important facts to help you make a responsible choice.

1. Boston Terriers Are Brachycephalic

One of the most notable features of Boston terriers is their flat face, a characteristic known as brachycephaly. Their short noses, large eyes, and compact skull shape create their trademark look, but also lead to some significant health considerations.

According to reputable Boston terrier breeders and UK veterinary experts, this facial structure can contribute to breathing difficulties and other health issues, including stenotic nostrils and an elongated soft palate. The Kennel Club Charitable Trust funded research at the University of Cambridge in 2025 emphasises the importance of responsible breeding to reduce these risks and improve respiratory health.

2. Health Challenges Linked to Brachycephaly

The primary health problem Boston terriers face is Brachycephalic Obstructive Airway Syndrome (BOAS), which can cause breathing difficulties, especially in hot weather or during exercise. Some dogs have more severe manifestations depending on their facial flatness and nostril shape.

Other common health issues include eye problems such as corneal ulcers, patellar luxation (knee joint issues), spinal malformations like hemivertebrae, and endocrine disorders such as Cushing’s disease. Regular vet check-ups and early recognition of symptoms are crucial to maintaining your dog's well-being.

3. Boston Terriers Are Not Toy Dogs

Though small and charming, Boston terriers are not classified as toy or lapdogs. Their history as utility dogs includes working roles like ratting and, historically, dog fighting, though the latter is rightly outlawed in the UK.

4. Good Watchdogs but Not Guard Dogs

Boston terriers tend to be alert and vocal, often barking to warn their owners of someone’s approach. While they are not suited as guard dogs due to their friendly and personable nature, their watchdog ability means they are attentive companions at home.

5. Moderate Exercise Needs

They require a couple of daily walks of about 30-45 minutes each, which is manageable for most owners. However, special care must be taken to avoid over-exertion or overheating, especially given their brachycephalic features that make breathing harder.

6. Purchase Costs and Ongoing Expenses

Boston terriers can be quite costly to buy, with pedigree puppies averaging around £1,000, and non-pedigree dogs often priced near £800. While their small size means they don't eat much, health-related vet bills and insurance can be more costly than average due to their potential medical issues.

7. Intelligence and Training

Ranked in the lower to middle range for canine intelligence, Boston terriers may take a bit longer than some breeds to learn commands and may not always obey reliably. Nevertheless, they are eager to please, which helps in training, especially with patience and positive reinforcement.

8. Affectionate and People-Oriented

They thrive on human companionship, are affectionate and enjoy spending time with their family. Boston terriers are often described as soulful and gentle, making them perfect for relaxed evenings and close bonding.

9. Separation Anxiety Risk

Boston terriers do not like being left alone for long durations and may develop separation anxiety. They need owners capable of spending significant time with them, making them less ideal for people who work long hours away from home.

10. Suitable for First-Time Owners with Research

Although relatively low-maintenance in terms of grooming and exercise, potential first-time owners must fully understand the breed’s special health considerations. Extensive research about brachycephalic dogs and consulting with trusted reputable breeders is highly recommended before deciding to bring a Boston terrier home.

What should you ask when buying a Boston terrier puppy?

Quick Answer: Ask about the puppy’s health screening, parents' health history, breathing and eye conditions, KC registration status, temperament, and early socialisation practices.

Detailed questions ensure you get a healthy, well-adjusted puppy from a responsible breeder. Always check for veterinary health clearances for conditions common to the breed and request to meet the puppy’s parents to assess their health and behaviour.

How to care for a Boston terrier's breathing needs

Quick Answer: Avoid overexerting your Boston terrier in hot weather, provide cool resting areas and monitor for breathing difficulties during activity.

Due to their brachycephalic anatomy, Boston terriers can suffer from heatstroke and breathing issues if over-exercised. Walk your dog during cooler hours, use shaded areas, and watch for signs of distress such as excessive panting or coughing. Regular vet checks can help identify any respiratory problems early and maintain quality of life.
