The American Bulldog-Mastiff mix, also known as the American Masti-Bull or American Bandogge, is a designer breed first developed in the 1960s by crossing American Bulldogs with Mastiffs. Originally conceived by veterinarian John Swinford to create an ideal guard dog, this hybrid combines the Mastiff's imposing size with the Bulldog's agility and courage. These large to giant-sized dogs typically weigh 100-140 pounds and stand 25-29 inches tall at the shoulder. While naturally protective, they display a gentle temperament with family when properly trained and socialized. Their moderate exercise needs and minimal grooming requirements make them suitable for experienced dog owners.

American Bulldog Mixed with Mastiff Variants

Breed Development History

The American Masti-Bull was first developed in the 1960s by two key figures - veterinarian John Swinford and breeder Joe Lucero. Their goal was to create an optimal guard dog by combining the American Bulldog's agility with the Mastiff's size. The term "American Bandogge" emerged from the Saxon word "Bandog" meaning chain, as these dogs were traditionally chained during day and released at night for guard duty.

Variants and Price Range

Different Mastiff breeds can be mixed with American Bulldogs to create distinct variants. The Bullmastiff American Bulldog mix, also known as American Bandogge, costs between $600-$2,500. The price variation depends on factors like breeder reputation, lineage, health screening, and the puppy's age and sex. The Italian Mastiff (Cane Corso) American Bulldog mix represents another variant, combining the traits of both parent breeds. The most successful breeding combination typically involves crossing a male American Pit Bull Terrier with a female Neapolitan Mastiff, though various other Mastiff-Bulldog combinations are recognized by kennel clubs.

History and Origins of the American Bulldog Mastiff Mix

Ancient Ancestral Roots

While the previous section covered modern breed development, this section explores the deeper historical foundations. The American Masti-Bull inherits a rich legacy from both parent breeds. The Mastiff's history dates back to ancient times, with documentation from Caesar in 55 B.C. and Egyptian monuments from 3000 B.C. The American Bulldog's lineage traces to 17th century British bull-baiting dogs that arrived during colonial times, particularly preserving traits of working dogs that survived in the American South.

Evolution of Working Roles

The parent breeds' working histories shaped the mix's development. American Bulldogs were utilized in the southern United States for catching feral pigs and cattle, while maintaining their protective instincts. The American Bandogge breeding program specifically aimed to combine the Mastiff's imposing size and strength with the Bulldog's agility and tenacity. This strategic breeding created a versatile working dog capable of both protection and companionship. The American Kennel Club recognized the Mastiff in 1885, though the American Bulldog remains unrecognized, reflecting the complex journey of breed standardization.

Physical Characteristics and Temperament

Size and Build Specifications

While previous sections discussed variants and history, this section focuses on specific physical traits. The Bullmastiff American Bulldog mix stands 25-29 inches tall at the shoulder, with females being slightly smaller than males. These dogs typically weigh between 100-140 pounds, making them a large to giant breed. Their physical structure combines the Mastiff's broad head and solid build with the Bulldog's muscular frame. They require minimal grooming but are known for significant drooling.

Behavioral Traits and Family Compatibility

The American Masti-Bull exhibits a complex temperament combining loyalty and protectiveness. These dogs display strong alpha personalities and require experienced handlers who can establish themselves as pack leaders. Despite their intimidating appearance, they show remarkable affection toward family members, particularly children, and can adapt well to apartment living when properly trained. Their moderate activity level requires daily exercise to prevent boredom-related behavioral issues. While generally friendly with other dogs, early socialization is crucial for developing balanced behavior. These dogs demonstrate independence, often seeking their own space while maintaining protective instincts toward their family.

Health and Care Requirements

Genetic Health Considerations

While previous sections covered physical traits and temperament, this section focuses on specific health concerns. The American Bulldog-Mastiff crosses can inherit several genetic predispositions from both parent breeds. The Italian Mastiff American Bulldog mix is particularly prone to cardiac and respiratory issues, hip dysplasia, and cherry eye. These large dogs are especially sensitive to heat problems, requiring careful monitoring during warm weather. Due to their hybrid nature, they may avoid some inherited conditions, but health screening of parent breeds remains crucial for responsible breeding.

Nutrition and Exercise Management

These dogs require specialized care to maintain their health and prevent obesity-related issues. Due to their predisposition to joint problems, supplements like fish oil, glucosamine, and chondroitin are recommended from an early age. The Bullmastiff American Bulldog mix has a life expectancy of approximately 10 years, typical for large breeds. Their moderate energy levels necessitate daily exercise, but activities should be balanced to prevent strain on their joints. A consistent feeding schedule with appropriate portions is essential, as these dogs are prone to weight gain. Their grooming needs are moderate, requiring weekly brushing, though owners should be prepared for significant drooling.

Conclusion

The American Bulldog mixed with Mastiff represents a purposefully developed hybrid breed that combines the agility and tenacity of the American Bulldog with the size and strength of the Mastiff. First developed in the 1960s, these dogs, also known as American Masti-Bulls or American Bandogges, typically weigh between 100-140 pounds and stand 25-29 inches tall. The breed demonstrates a complex temperament, featuring strong protective instincts balanced with remarkable family affection, though they require experienced handlers due to their alpha personalities.

Key considerations for potential owners include the breed's genetic health predispositions, particularly to cardiac issues, hip dysplasia, and heat sensitivity, as well as their specific care requirements. While these dogs can adapt well to apartment living with proper training and exercise, they need consistent leadership, early socialization, and careful health monitoring. Their moderate exercise needs and grooming requirements, combined with a typical lifespan of 10 years, make them suitable companions for experienced dog owners who can provide appropriate care and training. Prices for these dogs range from $600-$2,500, reflecting factors such as breeder reputation and health screening.
