What two breeds make an American bulldog?

The American Bulldog was primarily developed from the Old English Bulldog and various working bulldog types used in the southern United States.

Understanding the Origins of the American Bulldog

The American Bulldog is a powerful, intelligent, and loyal breed with a rich heritage rooted in American and British history. Bred originally for working on farms and guarding property, this breed is known for its agility, confidence, and affectionate nature with its family. To truly appreciate the American Bulldog, it’s essential to explore its origins and the specific breeds that contributed to its development.

The Ancestors of the American Bulldog

The American Bulldog's lineage traces back to two primary canine types:

  • Old English Bulldog
  • Southern working bulldog types

Each of these breeds played a critical role in shaping the American Bulldog's physical and behavioral characteristics.

1. Old English Bulldog

The Old English Bulldog was a compact and muscular dog originally bred in England for bull-baiting. Despite its fierce past, the breed was exceptionally loyal and determined. When English immigrants brought these dogs to the American South in the 17th and 18th centuries, farms and plantations became their new domain. Here, their protective instincts and strength proved invaluable.

2. Working Bulldogs in the American South

Over time, American farmers and immigrants selectively bred their Old English Bulldogs with other working dogs to enhance desirable traits like:

  • Endurance
  • Agility
  • Drive and tenacity
  • Loyalty to family

This led to the evolution of a more athletic and functional bulldog well-suited for guarding, hunting wild pigs and cattle, and performing grueling farm tasks.

Evolution into the Modern American Bulldog

During the early to mid-20th century, a few dedicated breeders helped define and revitalize the American Bulldog. Among them were John D. Johnson and Alan Scott. Their efforts resulted in two recognized lines:

  • Johnson Type: More muscular with a larger frame, often featuring a broader head and shorter muzzle.
  • Scott Type: More athletic and agile, characterized by a narrower head and longer muzzle.

Both lines share a common ancestry with the Old English Bulldog but differ slightly to accommodate their respective functional requirements.

American Bulldog Traits

Thanks to its ancestors, the American Bulldog is recognized for many unique traits:

  • Height: 20–28 inches at the shoulder
  • Weight: 60–120 pounds
  • Temperament: Loyal, alert, confident, and affectionate
  • Exercise Needs: High; thrives with regular physical activity

Its body is muscular and sturdy, built for both strength and agility. The head is typically broad with a strong jaw, reflecting its heritage as a powerful working dog.

Temperament and Family Life

The American Bulldog, despite its fierce appearance, is incredibly affectionate with family members. It tends to form strong bonds with owners and is known to be protective and nurturing with children. However, proper training and early socialization are essential to ensure balanced behavior with other pets and strangers.

Health Considerations

Like many pedigree dogs, the American Bulldog can be susceptible to specific health issues partly due to its lineage. Common conditions include:

  • Hip dysplasia
  • Elbow dysplasia
  • Entropion (inward-turning eyelids)
  • Skin allergies

Responsible breeding practices and routine vet check-ups help mitigate these concerns.

Conclusion

The American Bulldog is the product of careful, purposeful breeding that dates back centuries. The foundational breeds—the Old English Bulldog and various southern working types—came together to create a family-oriented yet rugged dog capable of performing demanding physical tasks. Today’s American Bulldog is not just a capable worker but also a cherished family companion. Understanding its roots helps us appreciate the breed’s unique characteristics, strengths, and enduring appeal.
