Boerboels are intimidating but discerning guardians of home and family who learned their trade while protecting remote South African homesteads from ferocious predators. Dominant and confident, they are also bright and eager to learn — the calm, stable, and confident composure of the breed is much sought after.

The gigantic Boerboel, also known as the South African Mastiff, is South Africa's answer to the Mastiff. The name says it all: "Boer" means farmer, and "boel," loosely translated, is a large dog. This imposing mastiff-type breed was originally bred to protect South African farms from predators — including hyenas and lions.

A South African Landrace

The Boerboel came into being in South Africa in the 1650s, when Jan van Riebeeck's family dog — a Bullenbeisser, literally "biter of bulls," a now-extinct breed believed involved in the Boxer's development — bred with the indigenous domestic dogs of the area. The breed descends from an old colonial cross of mastiffs and bulldogs used both as a guard dog on remote farms and estates and for big game hunting, known as the Boer Dog. The dangers and harsh conditions of southern Africa allowed only the fittest to survive.

Centuries later, DeBeers imported some of Britain's finest Bullmastiffs to patrol its famous diamond mines, and longer-legged Bulldogs came in with the British — helping solidify the Boerboel's appearance, best understood by its degree of "bulldogginess." These dogs were often the first line of defense against predators and were valuable in tracking and holding down wounded game.

It wasn't until the 1980s that people began working to preserve and perfect the Boerboel breed — the Suid-Afrikaanse Boerboel Telersvereniging was established in 1983. In South Africa, the Boerboel is regarded as a landrace under the Animal Improvement Act, with the South African Boerboel Breeders' Society as the only organization authorized to register the breed. The American Kennel Club recognized the Boerboel in 2015.

Large, Strong, and Muscular

The Boerboel is a large dog — strong, confident, and muscular in appearance, with powerful, free-flowing movement. Males stand 24 to 27 inches; bitches 22 to 25 inches, with full-grown dogs weighing 150 to 200 pounds. The body has a greater total length than height in a ratio ideally of 10:9, with a deep chest reaching to the elbow.

The breed has a distinctive head — broad and blocky, with a short muzzle and a little brow wrinkle when interested. The medium, V-shaped ears hang forward, and the face is intelligent. The coat is short, sleek, and shiny, in brown, red, fawn, or brindle, sometimes with a black mask.

Dominant, Confident, and Protective

The Boerboel is a dominant and intelligent dog with strong protective instincts and a willingness to please. When approached, it is calm, stable, and confident, at times displaying a self-assured aloofness — it should recognize a threat or lack thereof. It is loving with children and family.

Boerboels are strong and fearless with guardian instincts, yet very playful and affectionate toward their owners. They are gentle with the family's children and tend to do fine with other pets, including cats and other dogs, as long as they are properly introduced. Because they've been bred as guardians, Boerboels can view new people, animals, and situations with suspicion.

Exercise and Activity

Despite their docile nature at home, Boerboels are quite agile for a mastiff-type dog — in fact, the most agile of the molosser breeds — and need to be kept physically and mentally stimulated. Their needs can be met with daily long walks (always on a leash) or playtime in a fenced yard. If their needs are not met, they can become destructive and have been known to chew.

DogDaily exerciseNotes
Puppy3–4 short play sessions of 10–15 minutesKeep walks gentle; avoid hard surfaces while growing
Adult30–45 minutes total walk or playSplit into two shorter sessions if preferred
Senior20–30 minutes of gentle walkingSlow the pace and shorten distance with age

Boerboels love to play fetch and are great at activities like competitive obedience, rally, weight pulling, herding, agility, and even therapy work. The Daily Exercise Guide offers ideas for exercising a large guardian breed.

Training a Boerboel

Training and socialization are very important for Boerboels. They can be dominant and stubborn, so beginning training while they are puppies is your best bet — clear, consistent direction and boundaries from an early age help ensure an obedient and stable pet. Boerboels need a trainer who will consistently set boundaries and use positive reinforcement.

Early socialization helps them learn that new people, animals, and situations are not scary or threatening. A home with experienced pet parents dedicated to socializing and training their Boerboel puppy is a must — this is not a breed for an inexperienced or weak-willed owner. The Dog Training Guide and Puppy Care Guide offer a solid foundation.

Grooming a Boerboel

The Boerboel has a short, smooth, dense coat that is easy to care for — a weekly brushing keeps it in good condition. Routine care includes nail trimming, ear cleaning, and tooth brushing.

TaskFrequencyNotes
Brushing1–2 times a weekBrush in the direction of the coat and check for tangles
BathingEvery 6–8 weeks or as neededUse a mild dog shampoo
Nail trimmingEvery 3–4 weeksTrim when you hear nails clicking on the floor
Ear checksWeeklyLook for wax, redness, or odor
Teeth brushing2–3 times a weekDental chews help as a supplement

The Dog Grooming Guide covers caring for a short-coated breed.

Feeding a Boerboel

Full-grown South African Boerboels can weigh 150 to 200 pounds, which means they need a lot of food — typically up to about 10 cups every day. Make sure you have the budget for this big eater, and always talk to your veterinarian about how much you should be feeding your dog.

Life stageMeals per dayPortion per meal (approx.)Notes
Puppy (under 6 months)3–4 meals1–1.5 cupsUse a large-breed puppy formula
Adult2 meals2–3 cupsAdjust to activity level and body condition
Senior (7+ years)2 meals1.5–2.5 cupsConsider a senior or joint-support formula

Feed measured meals twice a day rather than free-feeding. Because the breed is deep-chested, it should eat calmly and avoid vigorous exercise around meal times as part of bloat awareness. Your veterinarian can guide you on portions.

Health and Veterinary Care

Like other giant-breed dogs, the Boerboel generally has a shorter lifespan than small breeds — typically 9 to 11 years. During its life it can develop a handful of health conditions, including hip or elbow dysplasia, vaginal hyperplasia, ectropion and entropion, allergies, and juvenile epilepsy. As a large, deep-chested dog, it can also be prone to stomach bloat and torsion.

Responsible breeders screen for genetic problems that commonly affect the breed. Don't hesitate to ask your breeder about the health histories of their dogs and puppies. The Signs of a Healthy Pet guide is a useful home checklist.

Home Environment

At home, Boerboels are generally calm. Their gentle demeanor makes them suitable in families with children who understand how to interact with dogs, but they may be best in homes without smaller children who could be easily harmed by an accidental bump or squish from this enormous dog. The breed is famed for being a doting nanny of the children in its family circle.

Because they can reach 200 pounds, these dogs require a lot of food and space — they won't do well crammed into a little apartment and prefer a fenced yard where they can sniff and roam. If you're not home, they won't let anyone into the house unless they know them really well. If you're weighing whether a Boerboel fits your life, the Choosing the Right Pet guide can help you compare honestly.

Common Ownership Challenges

Owning a Boerboel means committing to a giant guardian with immense power. The breed can be intolerant of strangers and is traditionally not wild about canines of the same sex — concerns over aggression have resulted in bans in some countries. The sheer size and power make extensive socialization essential, and the breed's need for food, space, and mental stimulation is substantial. It's also a rare breed with waiting lists.

Yet for the right owner, the Boerboel is unmatched — a calm, stable, confident protector that is loving with children and devoted to its family. From the remote homesteads of South Africa, where it has defended against lions and hyenas for centuries, to modern homes, the discerning South African farm guardian remains a loyal and formidable friend.
