Boerboel — The South African Powerhouse

The Boerboel was developed in South Africa as an all-purpose farm guardian. These dogs had to protect homesteads from predators and human threats, work around livestock, and live closely with the family. They needed strength, intelligence, stamina, and good judgment—traits that remain at the core of the breed today.

English Mastiff — The Gentle Giant

The English Mastiff is one of the world's oldest breeds. Historically used as a war and estate guardian, modern Mastiffs have been selectively bred into calm, tolerant, gentle giants that are more likely to nap at your feet than chase down an intruder.

Bullmastiff — The Silent Protector

Created in 19th-century England for gamekeepers, the Bullmastiff was designed to track and quietly detain poachers. They are powerful yet surprisingly quiet dogs, bred to disable rather than attack outright.

Cane Corso — The Italian Athlete

The Cane Corso, often called the Italian mastiff, was developed as a versatile farm and protection dog. Corso are athletic, intense, and highly trainable, often thriving in homes that give them a real job to do.

Neapolitan Mastiff — The Armored Guardian

The Neapolitan Mastiff, with its heavy wrinkles and loose skin, carries the look of an ancient guardian. Bred to be intimidating and physically imposing, the Neo is a traditional estate guardian with a naturally suspicious outlook toward strangers.

Key takeaway: the Boerboel sits in a sweet spot between sheer bulk and real athleticism. The English Mastiff is typically the heaviest, the Cane Corso the most agile, while the Boerboel balances both power and functional movement.

Boerboel Temperament

Boerboels are highly intelligent, confident, and deeply bonded to their families. They are observant and tend to think before acting, which makes them outstanding natural guardians. However, their strength and protective instincts mean they are not ideal for inexperienced owners and absolutely require early socialization and consistent training.

English Mastiff

English Mastiffs are known as classic gentle giants. They tend to be calm, tolerant, and slow to react. While they can still be protective, they rely more on intimidation and presence than on active engagement with threats.

Bullmastiff

Bullmastiffs are brave, steady, and relatively quiet. Historically bred to move silently and confront intruders, many still maintain that restrained, watchful nature. They are devoted to their families but often less intense than Boerboels or Cane Corsos.

Cane Corso

The Cane Corso is typically more intense and driven than the average mastiff. They are alert, territorial, and very trainable, often excelling in obedience or sport with the right handler. They generally do best with owners who have experience with working breeds.

Neapolitan Mastiff

Neapolitan Mastiffs are aloof, deeply loyal to their people, and naturally suspicious of strangers. They are lower energy than a Boerboel or Cane Corso but project immense presence. Their temperament is well suited to property guardianship and quieter households.

When it comes to training and real working roles, not all mastiffs are created equal.

• Boerboel: High trainability, strong working instinct, good problem-solving ability.
• Cane Corso: High trainability, excellent for structured work and sport.
• Bullmastiff: Moderate trainability, strong natural guarding skills.
• English Mastiff: Low–medium trainability, more companion than worker.
• Neapolitan Mastiff: Lower trainability, best as a deterrent-style guardian.

Boerboels and Cane Corsos sit at the top of the mastiff group in terms of structured work and trainability, but the Boerboel often brings a more balanced mix of biddability, power, and stability in a family context.

Every giant breed comes with health considerations, especially joints, heart, and overall longevity.

• Boerboel: Approx. 10–12 years with good breeding and management.
• Cane Corso: Approx. 9–12 years.
• Bullmastiff: Approx. 7–9 years.
• English Mastiff: Approx. 6–10 years.
• Neapolitan Mastiff: Approx. 6–9 years.

Boerboels are often one of the longer-lived mastiff breeds, thanks to their working heritage and emphasis on functional structure. Responsible breeders still screen for hip and elbow issues, cardiac problems, and other hereditary conditions.

There is no single "best" mastiff; there is only the best match for your lifestyle.
