Boerboel Dog Breed Information
Also known as: South African Mastiff, South African Boerboel, Borbull
A large, powerful South African farm guardian bred to hold leopard and protect remote homesteads. Legal in NZ but a serious commitment, with strict containment expectations and a temperament that demands an experienced owner.
A highly affectionate, great with young children dog. On the practical side: low grooming demands. The trade-off is drooly.
About the Boerboel.
The Boerboel is the South African farm guardian, bred over three centuries to protect remote homesteads from leopard, baboon and intruders. In New Zealand the breed is legal but uncommon, kept almost entirely on lifestyle blocks and farms across Waikato, Hawke’s Bay, Canterbury and rural Otago by experienced owners who understand the temperament and the containment requirements. This is one of the few breeds where buying without prior large-guardian experience is genuinely the wrong call.
Adults stand 59 to 70 cm at the shoulder and weigh 60 to 90 kg, with adult males commonly at the upper end. The coat is short, dense and smooth in fawn, red, brindle, brown or piebald, almost always with a black mask. The build is heavier and more athletic than an English Mastiff, less rangy than a Cane Corso, and clearly purpose-built for sustained physical work in a hot climate.
The Boerboel sits on the import-restricted list in Denmark, the canton of Geneva and several other jurisdictions. New Zealand has no breed-specific legislation against the Boerboel and registration with the local council under the Dog Control Act is standard, but the responsibility that goes with the breed is real. Containment failure with a 70 kg guardian is a public-safety incident, not a nuisance complaint.
Personality and behaviour
Boerboels are deeply bonded to their household and indifferent to almost everyone else. The breed default is calm, watchful and physically present in the room rather than hyper-vigilant. A well-raised adult lies in a doorway tracking the family, gets up to investigate noise, and settles again when satisfied. The breed is not prone to nuisance barking; the alert is usually a single deep bark followed by movement to the perimeter.
The protective instinct is the defining trait. Boerboels read the line between household members, accepted visitors and strangers, and respond with intent if that line is crossed without escort. Early, broad socialisation under 16 weeks (different people, places, surfaces, sounds) is the difference between an adult that copes calmly with a delivery driver and one that escalates. This is not a breed where socialisation is optional or done late.
Around other dogs, Boerboels are typically civil with house companions raised together and unforgiving of unfamiliar dogs that push the line. Same-sex aggression in adult Boerboels is well-documented and most breeders place puppies in single-dog or mixed-sex homes. Dog parks rarely work for adults; lead walks in quieter areas are the norm.
The trait that surprises new owners is sensitivity. Boerboels read handler tone and household atmosphere closely. The breed responds poorly to harsh corrections, panics under shouting, and sulks for hours after a fair telling-off. The temperament is not the cartoon “tough guard dog” of internet stereotype; it is a thinking, watchful working dog that needs a calm leader, not a loud one.
Care and exercise
Plan on around 60 minutes of moderate exercise per day for an adult, split between a structured lead walk and calm off-lead time in a secure paddock. The breed is not built for endurance running and growth-plate development through the first 18 to 24 months means avoiding forced jumping, hard fetch and stair sprinting. Lifestyle-block paddocks and rural tracks are the natural environment.
Grooming is the easiest part of the breed. A weekly rub-down with a rubber curry handles year-round shedding, with a heavier two-week blow in spring and autumn. Skin folds around the muzzle and jowls need wiping clean a few times a week to prevent yeast build-up. Drool is moderate to heavy and increases around food and water; a face cloth near the back door is part of the household kit.
The dietary priority is controlled growth and bloat management. Use a giant-breed puppy formula until 18 to 24 months. Adults eat 5 to 8 cups of food a day, split into two meals. Single large meals raise gastric torsion risk. Many NZ giant-breed owners arrange a prophylactic gastropexy at desexing (NZ$1,200 to NZ$2,500), which is meaningfully cheaper than emergency GDV surgery (NZ$6,000 to NZ$12,000).
Containment is a non-negotiable cost line. Six-foot fencing on every boundary, gates that latch and lock, and a secure gate at the driveway are baseline. Boerboels are perimeter-driven guardians; an open gate is an invitation, not a mistake. Many NZ Boerboel owners install double-gate driveways and keep the dog inside or in a secure run when contractors visit.
The dog beds, crates, vehicles and vet bills run at giant-breed scale. Adult Boerboels need orthopaedic beds at 110 cm or more (NZ$250 to NZ$600 each), XXL crates (NZ$350 to NZ$700), and a vehicle large enough to transport a 70 kg dog without the dog riding in the front seat. Council registration in NZ is standard; some councils impose a higher fee for unneutered dogs, which adds NZ$100 to NZ$200 a year.
Heat management matters in upper North Island summers. The breed’s heavy build slows recovery from exercise and overheating sets in faster than owners expect above 25 degrees. Walks at dawn or after 7 pm December through February, deep shade through the day, and access to fresh water are the basics. The short coat is no help in heat; it sheds water cleanly in winter rain but does not insulate against summer sun the way a double coat does.
Finding a Boerboel in NZ takes patience. The Dogs NZ breeders directory lists the small group of registered NZKC Boerboel breeders. Litters are uncommon; expect 12 to 24 month waitlists for puppies from health-tested parents at NZ$2,500 to NZ$5,500. Reputable breeders will show you hip, elbow and cardiac results on both parents, ask serious questions about your home, fencing and prior large-breed experience, and decline placements they judge unsuitable. That is the breed working as it should.
Boerboel rescue is rare in NZ. The occasional adult comes through SPCA or breed contacts after a life change or a containment failure. Adoption requires prior large-guardian experience and a property assessment in most cases.

What to ask the breeder.
Reputable NZKC breeders test for these conditions and share results without being prompted. If a breeder won't share screening results, that is itself an answer.
Common
1 conditionHip and elbow dysplasia
The heavy frame loads joints hard. Ask breeders for hip and elbow scores on both parents.
Occasional
5 conditionsBloat (gastric dilatation-volvulus)
Deep-chested breed; feed twice daily and avoid hard exercise around meals.
Vaginal hyperplasia
A breed-specific reproductive issue in entire females. Discuss desexing timing with your vet.
Ectropion and entropion
Eyelid abnormalities that may need surgical correction in young adults.
Cardiac disease
An occasional condition in the Boerboel. Worth asking about and DNA testing where available.
Cruciate ligament rupture
Heavy weight on the cranial cruciate ligament makes rupture a recognised claim category in giant guardians.
The Boerboel in NZ.
- Popularity: A small, niche presence in NZKC Utility registrations, mostly on lifestyle blocks across Waikato, Hawke's Bay, Canterbury and rural Otago. Numbers are low (a few hundred nationally) and waitlists from registered breeders are long.
- Typical price: NZ$2500–5500 from registered breeders
- Rescue availability: rare
- NZ climate fit: The short, dense coat handles the full NZ climate range. Heat is the primary concern in upper North Island summers; the heavy build slows recovery and requires shade, water and timed walks. Cold winters in Otago and Southland are no problem with insulated indoor sleeping space.
- Living space: Suits a lifestyle block or farm with secure six-foot fencing on every boundary. Boerboels are perimeter-driven guardians and need defined territory, not open access to the road. Containment failure with this breed is a genuine public-safety issue, not an inconvenience.
