Boston Terrier vs French Bulldog Size
The first visible difference between the two breeds is size. Despite similar heights, the French Bulldog is noticeably heavier and more compact in build.
Boston Terrier
- Height: 11–17 inches
- Weight: 11–25 lbs
- Build: lean and athletic
French Bulldog
- Height: 11–15 inches
- Weight: 16–28 lbs
- Build: muscular and stocky
The Boston Terrier is taller and more lightly built, with a sleeker silhouette. The French Bulldog is shorter but heavier, with a barrel-chested, powerfully muscled frame. The French Bulldog has the breed's distinctive large "bat ears" with rounded tips, while the Boston Terrier's ears are smaller, sharper, and more triangular in shape.
How to Tell a Boston Terrier From a French Bulldog
Although the two breeds look similar at a distance, several visual clues make them straightforward to distinguish up close:
- Ears: French Bulldogs have large rounded "bat ears" that stand wide apart. Boston Terrier ears are smaller, sharper, and triangular — more like pointed pricked ears.
- Body shape: French Bulldogs are compact, barrel-chested, and very muscular. Boston Terriers are leaner and more athletic, with a visibly lighter build.
- Leg length: Boston Terriers typically have longer legs and stand taller, giving them a more upright, elegant stance.
- Face wrinkles: French Bulldogs have visible skin folds around the muzzle and below the nose. Boston Terriers have a notably smoother, flatter face with fewer pronounced wrinkles.
- Tail: French Bulldogs usually carry a very short, stubby screw tail. Boston Terriers have a slightly longer, straighter tail.
- Coat pattern: Boston Terriers almost always have the distinctive black-and-white "tuxedo" pattern. French Bulldogs come in a wider range of colours including fawn, cream, brindle, and pied.
Both breeds are affectionate, sociable, and excellent with families, but their day-to-day personalities differ in ways that matter when choosing between them.
Boston Terrier: Lively, playful, and alert. Boston Terriers are highly intelligent and genuinely enjoy training — they respond well to positive reinforcement and pick up commands quickly. They are energetic dogs that love games and interaction, making them excellent companions for active households. They are protective of their families despite their small size and make surprisingly effective watchdogs. They also tend to bond well with children and other pets when properly socialised.
French Bulldog: Cheerful, docile, and calm. French Bulldogs are affectionate and self-confident but have a noticeably more relaxed approach to life. They enjoy companionship but are happy to settle in for the evening rather than demand constant activity. Their independent streak can make training slightly more challenging than with the eager-to-please Boston — patience and consistency are more important with a Frenchie. They are equally well-suited to life with children and families.
Boston Terrier vs French Bulldog Diet and Feeding
Boston Terrier: Needs a balanced, high-quality diet with lean animal protein as the primary ingredient. Dry or wet food both work — the key is nutritional quality. Boston Terriers have moderately high energy levels and generally self-regulate their eating reasonably well.
French Bulldog: Food intake needs closer monitoring. French Bulldogs are prone to overeating and obesity, which places additional strain on their already-compromised respiratory systems and joints. Measured portions at set mealtimes — rather than free feeding — are essential. Treats should be limited and accounted for within the daily calorie total. Both breeds benefit from food formulated for small breeds with flat faces (brachycephalic breeds), which typically have smaller kibble and easier-to-digest ingredients.
Boston Terrier vs French Bulldog Health Problems
Both breeds are brachycephalic — their flat faces cause the same fundamental respiratory challenges. Brachycephalic Obstructive Airway Syndrome (BOAS) affects both breeds to varying degrees, causing laboured breathing during exercise and in hot or humid conditions. Neither breed should be exercised in high heat, and both are poor choices for owners who enjoy intense outdoor activity in warm climates.
Beyond the shared airway issue, each breed has its own specific health vulnerabilities:
Boston Terrier: The flat muzzle makes breathing difficult during exercise. Their narrow pelvis frequently requires caesarean delivery. Their prominent, protruding eyes are vulnerable to injury and scratches, and need regular monitoring. Boston Terriers are also prone to heart disease and skin tumours.
French Bulldog: Similar respiratory problems due to a short muzzle and narrow trachea. Puppies are born with large heads relative to the birth canal, making natural delivery difficult and caesarean sections common. French Bulldogs can also develop spinal problems (particularly IVDD — intervertebral disc disease) due to their compact build, as well as certain types of cancer and genetic malformations. For more on Frenchie-specific conditions, see our comprehensive French Bulldog vs English Bulldog guide.
⚠️ Important for both breeds: Avoid strenuous exercise in temperatures above 20°C (68°F). Never leave either breed in a car. Hot or humid conditions can escalate to heatstroke very quickly in flat-faced dogs. Always have fresh water available and monitor breathing during and after any exercise. Research by the University of Cambridge has identified brachycephalic breeds like French Bulldogs and Boston Terriers as being at significantly higher risk of BOAS (Brachycephalic Obstructive Airway Syndrome), with restricted nostrils and neck conformation among the primary physical indicators of respiratory distress.
Boston Terrier vs French Bulldog Grooming and Care
Boston Terrier: Has a smooth, short, fine, and shiny coat that requires minimal grooming. An occasional bath every 4–6 weeks and regular brushing with a soft bristle brush is sufficient. The face should be gently wiped with a damp cloth daily. Eyes and ears need regular inspection, and nails should be trimmed monthly.
French Bulldog: The coat itself is low maintenance, but the facial skin folds need daily attention. Moisture, food debris, and sweat accumulate in the wrinkles around the muzzle and under the nose — if not cleaned regularly, this leads to bacterial or yeast infections and a characteristic bad odour. A soft damp cloth or pet-safe wipe used daily prevents most fold-related skin problems. Ears, eyes, and nails need the same routine attention as the Boston.
Boston Terrier vs French Bulldog Shedding
Both breeds have short coats and are relatively low shedders compared to longer-coated breeds. However, neither is truly non-shedding — both release loose hairs year-round that are short, fine, and can work their way into upholstery and clothing.
The Boston Terrier typically sheds slightly less than the French Bulldog. Neither breed has a dramatic seasonal blowout. Regular brushing once or twice a week with a rubber grooming mitt or soft bristle brush significantly reduces the hair that ends up on furniture and clothing.
Boston Terrier vs French Bulldog Exercise Needs
Boston Terrier: Needs regular walks and outdoor play sessions in a safe, confined space. They enjoy games, fetch, and mentally stimulating activities. Exercise should be scheduled during cooler parts of the day — early morning or evening in summer — to avoid respiratory stress.
French Bulldog: Needs less exercise than the Boston Terrier. Two short walks of approximately 1–2 kilometres per day, plus brief play sessions, is sufficient for most adult French Bulldogs. Their stockier, more compact build means they tire slightly faster under exertion — which, combined with their airway limitations, makes shorter, more frequent exercise sessions a better strategy than one long outing.

| Less facial fold maintenance | Boston Terrier |
| Apartment living (low exercise) | French Bulldog |
Frequently Asked Questions: Boston Terrier vs French Bulldog
Are Boston Terriers and French Bulldogs related?
Yes. Both breeds share ancestry with bulldog-type dogs and were developed as companion breeds. They are not the same breed, but the shared brachycephalic (flat-faced) structure reflects their common bulldog heritage. The Boston Terrier is a cross between a Bulldog and a White English Terrier, while the French Bulldog descends from English Bulldogs crossed with Parisian ratting dogs in 19th-century France.
Which breed is easier to train?
Boston Terriers are generally easier to train. They are highly intelligent, eager to please, and respond quickly to positive reinforcement. French Bulldogs are also intelligent but have a more independent, stubborn streak — training works best with patience, consistency, and high-value rewards rather than repetitive drilling.
Which breed is better for apartments?
Both breeds adapt well to apartment living. The French Bulldog is marginally better suited because it requires less exercise and has a calmer temperament. The Boston Terrier can also thrive in a flat, but needs more daily activity to remain well-behaved. Neither breed should be left alone for long periods without mental stimulation.
Do Boston Terriers and French Bulldogs shed?
Both breeds shed moderately year-round. Their short, fine coats release loose hair continuously rather than in heavy seasonal blowouts. The Boston Terrier typically sheds slightly less. Weekly brushing with a rubber grooming mitt or soft bristle brush significantly reduces the hair that ends up on furniture and clothing.
Which breed is healthier?
Both breeds share the risks common to brachycephalic dogs — primarily breathing difficulties (BOAS) and heat sensitivity. French Bulldogs have a slightly higher incidence of spinal problems (IVDD) due to their compact build. Boston Terriers are more prone to eye injuries due to their prominent, protruding eyes. Neither breed is considered especially healthy; both benefit from pet insurance and regular veterinary monitoring.
Which is more expensive, a Boston Terrier or French Bulldog?
French Bulldogs are typically more expensive. A well-bred French Bulldog puppy costs $2,000–$5,000 in the United States, while Boston Terriers generally range from $1,500–$3,000. Both breeds require caesarean delivery in most cases, which adds to breeding costs. French Bulldogs also tend to have higher ongoing veterinary costs due to their higher rate of structural health issues.

Are Boston Terriers or French Bulldogs better for first-time owners?
Both breeds can be good choices for first-time dog owners. French Bulldogs are often easier for beginners because they require less exercise and have a calmer, more relaxed temperament. Boston Terriers may need more activity and training engagement, but their eagerness to please can actually make the training process straightforward. Either breed is a reasonable starting point for a first-time owner who has done their research on brachycephalic breed care.
