Bullmastiff vs Boerboel: Which Large Dog Is Best for Families?

Bullmastiffs and Boerboels are both large and commanding dog breeds, admired for their strength and impressive size. Many potential pet owners in the US face the question: which breed is the better fit for a family environment? This article breaks down the important traits of each breed to help you make a well-informed choice.

Bullmastiff Origins and Breed History

The Bullmastiff is a long-established breed that was developed in England mainly to serve as a hunting companion and guard dog. Its lineage includes the Bloodhound, Great Dane, and Saint Bernard, culminating in official breed recognition in 1925. Historically prized for their power and bravery, Bullmastiffs today have become gentle and devoted family protectors.

Boerboel Origins and Breed Background

The Boerboel originated in South Africa, where early settlers bred robust dogs to safeguard their farms and families. Their ancestry likely shares roots with European breeds such as the Bullmastiff. While Boerboels are less common in the US and not recognized by the American Kennel Club (AKC), they have a dedicated following within the country, especially among experienced owners.

Physical Appearance Comparison

Bullmastiff puppies are large, sturdy dogs, generally standing 24-25 inches tall at the shoulder and weighing between 90-130 pounds depending on sex. Their short, weather-resistant coat comes in shades of brindle, fawn, red, typically with dark masks on their faces.

Boerboels are similarly muscular but tend to be larger and heavier overall. Males can reach heights of 25-28 inches and weigh between 155-200 pounds. Their dense, short coat has a natural sheen and displays a broader color palette including mahogany, brindle, red, cream, and piebald patterns. This extra size should be considered when assessing living space and family needs.

Temperament and Family Compatibility

Bullmastiffs have earned the nickname "gentle giants" for their calm demeanor and loyalty. They develop strong attachments to their families and are generally patient and tolerant with children, especially those who have learned how to interact respectfully with large dogs. With proper early socialization and consistent training, Bullmastiffs make protective yet manageable watch dogs.

In contrast, Boerboels possess a pronounced guarding instinct and an alert, watchful nature. They radiate confidence and courage, sometimes displaying a stubborn and independent streak. This breed flourishes under the care of owners familiar with large, protective guardian dogs. They bond deeply with their family and are especially watchful around children, though their substantial size and energy may require additional caution in homes with very young kids.

Training and Behavior Management

While Bullmastiffs are intelligent, they can occasionally show stubborn behavior. Early introduction to training using gentle but firm leadership and positive reinforcement is key to nurturing balanced adult dogs. They respond well to owners who provide clear, kind boundaries.

Boerboels are quick learners as well, but their guarding tendencies demand careful management through early and ongoing socialization and consistent training. This breed is best suited for owners with experience handling strong, dominant dogs to avoid future behavioral issues.

Exercise Requirements and Energy Levels

The Bullmastiff generally enjoys a more moderate activity level, needing about an hour of daily exercise combined with mental engagement to stay content and avoid boredom. They can adapt well to less active lifestyles, making them popular among families preferring a steady routine.

Boerboels have more substantial athletic demands, reflecting their working dog history. They typically require 60 minutes or more of vigorous daily exercise to expend their energy and maintain health. Their owners should provide a mix of physical activity and mental stimulation to prevent restlessness.

Compatibility with Children and Other Pets

Families with older children who understand respectful behavior around dogs will find Bullmastiffs to be excellent companions. They commonly get along smoothly with other dogs and cats that live in the home, although supervision is advised when interacting with smaller or new animals.

Boerboels generally show a natural affection for children, especially in families with older kids. Like Bullmastiffs, early socialization is critical to establishing peaceful relationships with other household pets. Given their strength and size, care must be taken when around small children and animals to prevent accidental injury.

Health Considerations and Lifespan

Bullmastiffs share health risks common to large breeds, including hip and elbow dysplasia, gastric torsion (bloat), various cancers, and skin allergies. Responsible breeders in the US perform health screenings and recommend balanced diets to extend life quality, typically averaging 8 to 10 years.

Boerboels are prone to some inheritable conditions as well, such as epilepsy, hip and elbow dysplasia, and bloat. With proper veterinary care and nutrition, their expected lifespan ranges slightly higher, typically from 10 to 12 years.

Which Breed Makes the Better Family Dog?

Deciding between a Bullmastiff and a Boerboel boils down to your family’s lifestyle, experience, and home environment. The Bullmastiff suits those seeking a calm, loving, and slightly easier-to-handle guard dog who adapts well to laid-back households.

Boerboels are ideal for experienced dog owners prepared for an assertive, protective, and active canine companion. These dogs excel when their guarding instincts and alertness are directed productively through firm training and sufficient exercise.

Both breeds thrive with early socialization and dedicated training, transforming into affectionate and well-behaved members of your family. The decision should factor in size, temperament, and your willingness to meet the unique needs of these large breeds.

For anyone interested in acquiring a Bullmastiff puppy or a Boerboel puppy in the US, it's important to work only with reputable breeders dedicated to health testing, socialization, and responsible dog ownership practices.
