The American bulldog shares a common ancestor with the English bulldog, but the two breeds have diverged to the point of producing dogs with radically different sizes, abilities, and needs. Comparing these parameters allows us to measure what makes the American bulldog so special before considering adoption.
American Bulldog and English Bulldog: Table of Morphological and Behavioral Differences
Both breeds descend from the Old English Working Bulldog, but the selection made in the southeastern United States has produced a larger, more athletic, and significantly more enduring dog than its British cousin.

| Criterion | American Bulldog | English Bulldog |
|---|---|---|
| Height at the withers | 53 to 67 cm depending on sex | 31 to 40 cm |
| Weight | 30 to 55 kg | 18 to 25 kg |
| Exercise needs | High (sports activities, long walks) | Moderate (calm walks) |
| FCI recognition | Not recognized | Recognized |
| Classification in France | No category (neither 1 nor 2) | No category |
| Dominant temperament | Protective, very attached, energetic | Calm, not physically demonstrative |
The weight difference can reach double between a male American bulldog of the Bully type and an English bulldog. This size difference affects living space, food budget, and the type of outings to plan.
To learn everything about the American bulldog, it is also important to distinguish the three types that coexist within the breed: the Standard (more athletic silhouette, similar in appearance to a pitbull), the Bully (stockier, heavier), and the Hybrid, a cross between the two previous types, which today represents the majority of dogs encountered in France.

Standard, Bully, or Hybrid Type: How the Choice of Type Affects Daily Life
This distinction is not cosmetic. The type determines the level of physical activity required each day. A Standard American bulldog, selected for agility and endurance by Allan Scott in the 1970s, requires more stimulation than a Bully type, developed by John D. Johnson for its imposing stature and strength.
The Hybrid combines these two lines. In practice, this results in a versatile dog, capable of keeping up with a sporty owner on hikes as well as adapting to a family pace, provided it is offered regular and varied outings.
Health Consequences by Type
The Bully type, heavier and more compact, has an increased predisposition to joint problems (hip dysplasia in particular). The Standard type, being lighter, is less exposed to this but remains prone to cataracts, a condition frequently cited in the breed.
Regular veterinary follow-up is essential regardless of the type. Preventive care (joint screening, ophthalmological assessment) helps anticipate these issues rather than suffer from them.
American Bulldog and French Legal Framework: Absence of Categorization and Real Obligations
One point that regularly generates confusion is that the size of the American bulldog suggests it could be classified among category 1 or 2 dogs under French law. This is not the case. The breed does not appear on any of the official lists of categorized dogs.
This absence of categorization means that no specific ownership permit is required, there is no muzzle obligation related to the breed, and the behavioral assessment imposed on category 2 dogs does not apply. However, general rules remain in effect:
- Identification by microchip or tattoo, mandatory for all dogs in France
- Rabies vaccination required for travel abroad and generally recommended
- Civil liability insurance covering damages that the animal may cause to third parties
The French Club of the American Bulldog, founded in 1999, works to structure the breed in the territory, but the FCI has still not issued an official standard. Registration therefore goes through alternative registries like the FBKC.
Adopting an American Bulldog: Criteria to Check Before Committing
Early socialization shapes the balance of the adult dog. The American bulldog naturally develops a protective instinct towards its family. Without regular exposure to other animals, varied environments, and unfamiliar people from the first weeks, this trait can drift towards excessive mistrust.
Profile of a Suitable Owner
This dog is not suited for a sedentary lifestyle. Its energy level demands daily vigorous outings, not just a walk around the block. Owners who engage in hiking, jogging, or canine activities (tracking, sports obedience) will find an tireless companion.
A well-socialized American bulldog integrates perfectly into a family with children. Its loyalty and “velcro” nature make it an endearing companion, provided its exercise and mental stimulation needs are respected.
Choosing a Reputable Breeder
The absence of FCI recognition makes the market less regulated than for other breeds. A few concrete guidelines help filter:
- The breeder presents screening results (dysplasia, eye assessment) of the breeding stock
- Puppies are socialized in a family environment, not isolated in kennels
- A sales contract details health guarantees and conditions for return in case of problems
- The breeder asks questions about your lifestyle before validating the sale
A breeder who does not inquire about your daily habits likely does not prioritize the dog’s well-being.
The American bulldog remains a dog whose size and temperament require a real commitment. Its diet represents a significant budget item for a dog that can exceed 50 kg. Before adoption, evaluating the annual cost (food, veterinary care, pet insurance) over the average lifespan of the breed provides a more accurate picture of the commitment than a sudden infatuation at a breeder.
