French Bulldogs and English Bulldogs share an ancestry that is visible in their appearance and written in their health risks. They are related breeds that diverged into distinct types over 150 years of separate development. Understanding where they differ, and where they are essentially the same, matters for anyone trying to decide which breed suits their circumstances.
Size and build
The most immediate difference is size.
English Bulldog: 23 to 25 kg for dogs, 18 to 23 kg for bitches. Height at the shoulder 30 to 36 cm. A substantial, low-slung dog with considerable mass in the chest and shoulders.
French Bulldog: Maximum 12.5 kg by the KC standard, typically 8 to 12 kg in practice. Height at the shoulder approximately 27 to 31 cm. Compact and muscular but significantly smaller.
The English Bulldog’s bulk makes it unsuitable for flat living in a way that a Frenchie is not. Transport in a car is more involved for an English Bulldog; carrying is not feasible as it is for a small Frenchie. Food costs are higher proportionally. And the scale of surgical procedures, from BOAS surgery to caesarean sections, reflects the size difference.
Both are front-heavy breeds with wide chests. Both carry their weight low. Both are not built for agility or speed.
Temperament
English Bulldog: Calm, steady and affectionate. English Bulldogs are famously placid; the breed’s temperament is typically described as gentle and docile, with a dignity that the active enthusiasm of a Frenchie does not always match. They are patient dogs with children and tend toward low-key companionship.
French Bulldog: Affectionate and playful but with a livelier energy than the English Bulldog. Frenchies are alert, often opinionated and can be stubborn. They attach strongly to their owners, which is a source of both their appeal and their susceptibility to separation anxiety. They are social with people but may be more variable with other dogs.
Both breeds are not naturally guard dogs in any serious sense, both are friendly with people they know, and neither has the independent working drive of a herding or sporting breed. The English Bulldog’s calmer baseline temperament makes it less demanding in terms of daily interaction, but the Frenchie’s alertness and responsiveness makes training more rewarding (when it goes well) and more frustrating (when it does not).
Exercise requirements
Both breeds are low-exercise dogs with significant heat sensitivity. The specific numbers differ only slightly in practice.
English Bulldog: 20 to 30 minutes of walking per day in mild weather. Very limited in hot conditions. Many English Bulldogs have severe enough BOAS to restrict exercise further than this minimum.
French Bulldog: 20 to 40 minutes per day in mild weather. Similar heat restrictions apply, with caution required above approximately 20°C.
Neither breed is suitable for owners whose lifestyle revolves around active outdoor pursuits, running or long hikes. Both breed’s exercise limits are set by their respiratory anatomy rather than fitness level or motivation.
Health
This is where the similarities are most significant and the differences matter most for long-term ownership.
Shared health concerns
Both breeds are brachycephalic, and both are consequently prone to:
- BOAS (Brachycephalic Obstructive Airway Syndrome)
- Skin fold infections (intertrigo), though English Bulldogs have more extensive folds and typically higher fold management demands
- Eye conditions including cherry eye and entropion
- Spinal conditions, particularly intervertebral disc disease (IVDD), to which both breeds are predisposed
- Birthing difficulties, with both breeds commonly requiring caesarean sections for delivery
Where English Bulldogs have greater health risk
BOAS severity. English Bulldogs as a population tend to have more severe BOAS on average than French Bulldogs, reflecting their typically more extreme brachycephalic conformation. The proportion of English Bulldogs requiring surgical airway intervention is higher.
Skin fold management. The English Bulldog’s more extensive facial and body folds require more intensive ongoing management. The deeper folds produce more recurrent infections in a higher proportion of dogs.
Hip and elbow dysplasia. More commonly tested for and found in English Bulldogs than in French Bulldogs, reflecting the heavier body weight placing greater stress on the joints.
Whelping. English Bulldogs almost universally require caesarean sections. The proportion is very high in Frenchies too, but the procedure carries slightly higher risk at greater body weight.
Where French Bulldogs have specific risks
Hemivertebrae. Spinal malformation is common in both breeds but French Bulldogs have a specific predisposition to hemivertebrae (wedge-shaped vertebrae), which can cause spinal cord compression and neurological signs.
Ear infections. French Bulldogs’ narrow ear canals create higher rates of recurrent ear infection than typically seen in English Bulldogs.
Grooming
English Bulldog: Higher grooming demand. The more extensive skin folds, heavier wrinkles and larger tail fold require daily or near-daily cleaning. The dewlap (skin folds on the neck and throat) also requires attention.
French Bulldog: Moderate fold care for facial folds, tail fold and ear cleaning. The overall surface area of fold-prone skin is smaller, making the routine less time-intensive, though equally important when the fold is infected.
Both breeds have short, low-shedding coats that do not require professional trimming.
Cost
Purchase price. Both breeds from KC-registered breeders with appropriate health testing in the UK are typically £2,000 to £3,500. English Bulldogs can command slightly higher prices at the upper end, reflecting the higher cost of caesarean sections in breeding.
Insurance. Both breeds are in the highest insurance premium brackets, reflecting their high claim frequencies. English Bulldog lifetime cover is typically slightly more expensive than Frenchie cover, but both significantly exceed the standard dog premium.
Food. The English Bulldog’s greater size means roughly double the food consumption of a Frenchie.
Veterinary. Both breeds generate above-average vet costs over a lifetime. English Bulldog vet costs tend to be somewhat higher on average due to the more frequent need for major BOAS intervention and the caesarean cost in breeding dogs.
Which suits your situation
If you are choosing between the two breeds, the practical questions to answer are:
Space. A French Bulldog is appropriate for flat living. An English Bulldog requires more space and is less suited to small properties.
Budget. Both require significant insurance and ongoing health investment. The English Bulldog’s higher size-related costs make the lifetime financial commitment greater.
Activity level. Both breeds suit low-activity owners. Neither is appropriate as a working-from-home exercise companion for an active person who expects the dog to keep up.
Temperament preference. For a calmer, steadier companion, the English Bulldog is often the better fit. For a dog with more personality and interactive engagement, the Frenchie.
Health commitment. Both require owners prepared to manage brachycephalic health proactively. The English Bulldog’s more intensive fold care demands should be factored in specifically.

Frequently asked questions
-
English Bulldogs are substantially larger. A male English Bulldog typically weighs 23 to 25 kg and stands 30 to 36 cm at the shoulder. A French Bulldog weighs a maximum of 12.5 kg by the KC standard and stands around 27 to 31 cm. The English Bulldog is roughly double the weight of the French Bulldog. This size difference has practical implications for feeding costs, transport, housing space, and the scale of any health procedures.
-
Both breeds present similar types of challenge: brachycephalic health considerations, heat sensitivity, whelping difficulties and ongoing health costs. The English Bulldog typically requires more feeding, takes up more space and has higher grooming demands around its larger and more numerous skin folds. The French Bulldog is more adaptable to flat or small-home living and has slightly lower daily maintenance requirements, but equivalent health monitoring needs. Neither is low-effort; both are breeds for committed owners.
-
Both breeds need moderate exercise with significant heat restrictions, but the English Bulldog's larger bulk and typically more severe BOAS presentation mean exercise tolerance is often lower. An English Bulldog may manage 20 to 30 minutes of walking in mild conditions; a Frenchie is similar but may have somewhat better heat tolerance by virtue of being smaller and generating less body heat. Neither breed is suitable as a jogging companion or high-activity dog.
-
English Bulldog puppies from registered breeders typically cost £2,500 to £3,500, similar to or slightly higher than French Bulldogs. Running costs are higher for English Bulldogs due to greater food consumption, higher insurance premiums reflecting the significant health costs of the breed, and the not-uncommon requirement for caesarean sections, which can cost £1,500 to £3,000. Both breeds are among the most expensive small to medium dogs to own over a lifetime.
-
Yes. The French Bulldog descends directly from miniaturised English Bulldogs. Small English Bulldogs were developed in the English Midlands in the mid-nineteenth century and taken to France by emigrating workers, where they were bred into the distinct French Bulldog type. The shared ancestry means both breeds carry similar predispositions: brachycephalic conformation, skin fold issues, spinal conditions and birthing difficulties. They are distinct breeds, but the family connection explains many of their shared characteristics.
