Is a Boerboel a Good First Dog?

We breed these dogs, and we are going to spend this page talking most first-time owners out of buying one. Below is the evidence we use to do it, including the numbers a breeder is not supposed to publish.

By Derek Peterson, Peterbuilt Boerboel · Livingston, Texas · Updated August 2026

The short answer

For most first-time dog owners, no. A Boerboel is a guardian breed whose males run 150-200 lbs, and across the 29 giant breeds in a 2026 UK veterinary study, aggression was recorded as a clinical disorder in 5.56% of dogs in a single year[1] against 2.24% across dogs overall.[3] Breed explains only about 9% of behaviour.[6] The other 91% is you.

That last sentence is the whole argument, so it is worth stating without the softening a sales page would add. A breeder can hand you genetics, health testing and eight weeks of early handling. Genetics is the 9%. Everything that determines whether the adult dog is a stable citizen or a liability, the socialization, the training, the containment, the supervision, the neutering decision, the feeding discipline, sits on the side of the ledger a first-time owner has never worked before, and it is the larger side by an order of magnitude.

There is a narrow exception, and we give it its own section further down with the conditions attached, because an exception stapled to the answer is not an answer. Read it there rather than here.

The number that costs us sales

In 2026 the Royal Veterinary College’s VetCompass programme published the largest giant-breed health study yet run: 29 giant breeds, 28,345 dogs drawn from 2,250,417 dogs under UK primary veterinary care, with every disorder recorded in a single year (2019) counted.[1, 4] Four of its findings belong in front of anyone thinking about a first giant-breed dog.

5.56%

Aggression, in one year

Aggression recorded as a clinical disorder in giant-breed dogs during 2019, 95% CI 4.88 to 6.24, the third most common precise-level disorder in the study.[1] The comparable figure across dogs overall is 2.24%, 95% CI 2.05 to 2.45.[3] More than double.

73.8%

Had a disorder recorded

Share of giant-breed dogs with at least one disorder recorded in a single year[1], against 65.84% for dogs overall.[3, 5] Roughly three in four giant dogs saw a vet for something in twelve months.

8.94 yrs

Median age at death

Median age at death across giant breeds, IQR 6.96 to 10.9.[1] Buyers price this decision as a twelve to fifteen year commitment. In the giant-breed group it is closer to nine. See Boerboel lifespan for the breed-level picture.

8.02%

Overweight or obese

Overweight and obesity recorded in giant-breed dogs in one year, 95% CI 7.21 to 8.83, the second most common disorder.[1] Read that as a management statistic: a meaningful share of giant-dog owners cannot hold the feeding line, and that is the easiest thing on this page to get right.

The study’s own conclusion is about body size rather than behaviour: the authors report a higher disorder burden and shorter lifespan in giant breeds than in the wider dog population, and call for discussion of welfare-based limits on selecting for extreme giantism, arguing that more moderate body sizes would improve both the quality and length of these dogs’ lives.[1, 5] That is a conclusion aimed squarely at breeders, including us.

Now the part that is against our commercial interest, said out loud. The 5.56% figure is the single most useful number a Boerboel buyer can have, and it is the number that will cost us the most sales. We publish it because a page that only lists reasons to buy is an advertisement, and because we would rather lose a deposit than place a dog into a home that is going to fail it eighteen months from now. If a breeder shows you only the affectionate-with-children photographs, you are reading marketing.

And the honest caveat that cuts the other way. This is a recorded-prevalence study: it counts what veterinarians wrote in clinical records, not verified bites. The same behaviour may well be written down as “aggression” more readily when the dog on the table weighs 140 pounds, which would inflate the giant-breed figure against the all-dogs figure. It could equally run the other way, with owners of giant dogs normalising behaviour they would report in a terrier. We do not know which dominates, so we treat 5.56% as a decision input rather than a verdict rather than present it as harder than it is. The underlying science of aggression and bite risk is handled properly on our Boerboel temperament page.

What we do not know, and will not pretend to

Every figure on this page from that study describes giant breeds as a group, not the Boerboel. We could not retrieve the paper’s Table 1, the list naming which 29 breeds were included, so we do not know whether the Boerboel is one of them, and we are not going to let the layout imply that it is. Treat 5.56%, 73.8%, 8.94 years and 8.02% as the giant-breed backdrop against which a Boerboel decision gets made. Every figure quoted here comes from the study’s published abstract[1], which we read directly; the full text was behind a login.[2]

You cannot buy temperament

Every breeder in this business, us included, says some version of “we breed for temperament.” In 2022 a study in Science surveyed the owners of 18,385 dogs and genotyped 2,155 of them. Most behavioural traits turned out to be genuinely heritable, with heritability above 25%. But breed explained just 9% of the behavioural variation between individual dogs.[6]

Turn that against the sales pitch and it does real damage. If breed accounts for 9% of how a dog behaves, then “we breed for temperament” cannot carry the load a buyer is asking it to carry. It is a true statement about a small effect. Good breeding meaningfully improves your odds, and it is not the reason your dog turns out well or badly. Nine percent is a tilt, not a guarantee, and the guarantee is what the unprepared buyer thinks they are purchasing.

This is why “are you experienced enough?” is arithmetic, not an insult. Roughly 91% of the outcome is produced by the socialization schedule, the training, the containment, the supervision and the daily management: everything the owner does. A first-time owner is not being told they are a bad person. They are being told that they have been assigned the large majority of the work on a dog that will outweigh them, with no reps.

One more consequence follows, and it is the useful one: because the owner’s share is so large, it is also the share you can change. Experience is buildable. That is what the exception section is about, and why the honest advice to most first-timers is “not yet” rather than “never.”

How it actually goes wrong

Three failure modes account for most bad outcomes with a first giant-breed dog. Each one below is tied to a study rather than to a feeling, because the version of this advice you usually read is somebody’s vibe.

1. The severe-bite failure is a stack of ownership decisions

The best study of severe outcomes is Patronek and colleagues in JAVMA, 2013: all 256 US dog-bite-related fatalities from 2000 to 2009, reconstructed from homicide detective reports, animal control reports and interviews with the investigators rather than from newspaper coverage.[7] Here is what co-occurred, with the paper’s own counts, and the column that matters most on the right.

Co-occurring potentially preventable factors in 256 US dog-bite-related fatalities, 2000 to 2009
Factor presentnShareWhose decision?
No able-bodied person present to intervene22387.1%Owner's supervision decision
Victim had only incidental or no familiar relationship with the dog21885.2%Owner's management decision
Dog was not neutered21684.4%Owner's veterinary decision
Victim's compromised ability to interact appropriately with the dog19877.4%Owner's supervision decision
Dog kept isolated from regular positive human interaction, not living as a family dog19576.2%Owner's housing decision
Owner's prior mismanagement of the dog9637.5%Owner's history
Owner's history of abuse or neglect of the dog5421.1%Owner's history

Four or more of these factors co-occurred in 206 of the 256 deaths (80.5%). A valid breed determination was possible in only 45 cases (17.6%).[7]

Read the right-hand column again. Every one of those factors is an ownership decision. Whether an able-bodied adult was in the room. Whether the dog knew the person. Whether the dog was neutered. Whether the dog lived with the family or lived alone on a chain or in a yard. None of them is a genetic trait, which is precisely why the authors found that breed was not among the preventable factors and could not even be validly determined in more than 82% of cases.[7]

For a first-time owner of a guardian breed this cuts in a specific direction, and it is the uncomfortable one. Every factor in that table is a decision an inexperienced owner of a 150 pound dog is more likely to get wrong: more likely to leave the dog alone with a visitor, more likely to keep the dog outside because it is easier, more likely to postpone the neutering conversation, more likely to misread a warning. The breed is not the risk factor. The gap between what the dog requires and what the owner has practised is the risk factor, and a giant guardian breed makes that gap as wide as it gets.

2. The surgery nobody warns first-time buyers about

In a study of more than 600,000 insured Swedish dogs between 2011 and 2016, 181 breeds had at least one claim for cranial cruciate ligament rupture. Of all 181, the Boerboel had the highest relative risk: 11.0, 95% CI 5.84 to 18.8.[8] That is the strongest breed signal in the paper, and it is ours.

Cruciate rupture in a giant dog is not a wait-and-see problem. It is orthopaedic surgery on a patient who is hard to crate-rest, often followed by rupture of the other stifle, and it is the single most common way a Boerboel budget goes from “manageable” to “we are having a difficult conversation.” Two caveats keep this honest: the cohort is Swedish and insured, which is not the same population as an uninsured US pet dog, and the Boerboel confidence interval is wide because the breed contributed few dogs. The lower bound of that interval is still 5.84, so the direction is not in doubt even if the point estimate is soft. The full disease picture, hips, elbows, ALPS, DNA panels and bloat, lives on our Boerboel health page, and the money side is on cost of ownership.

3. The dog ends up somewhere else

The classic case-control study of shelter relinquishment identified a set of modifiable factors, and they read like a checklist of first-year decisions: not participating in obedience classes after acquisition, little or no veterinary care, owning a sexually intact dog, and inappropriate care expectations.[9] The AVSAB adds the behavioural half of the picture: behavioural problems are the number one cause of relinquishment to shelters, and incomplete socialization in the first three months increases the risk of exactly those problems.[12]

Here is the counterweight, because leaving it out would be dishonest. A 2015 study of 166 relinquishers and 125 comparison households at a Los Angeles municipal shelter found that 76.9% of relinquishers cited cost, and that dog size and sex were not significantly associated with relinquishment in the final model.[10] In that community, money and household stress dominated animal characteristics. So the fair reading is not “big dogs get surrendered.” It is that the things which get any dog surrendered, cost, unmet expectations, no training, no vet relationship, all scale badly with size. A giant breed does not create the failure mode. It multiplies the price of it.

The disqualifier checklist

Most breed pages give you an aspirational list: be consistent, be confident, be a strong leader. Nobody has ever failed one of those. This list is written as disqualifiers. A “no” on any single item is a reason not to buy a Boerboel this year, and we would rather you found that out here than in month fourteen.

  1. 1. Can you physically hold this dog when it decides otherwise?

    Males commonly run 150-200 lbs, females 120-170 lbs, on the substantial guardian frame the breed standard calls for.[18] Not “can you walk a calm dog on a loose leash,” which anyone can do. Can you hold a dog that outweighs you when it has decided the man across the street is a problem? If the honest answer depends on the dog agreeing with you, that is a no.

  2. 2. Is the fence already up?

    Not planned, not quoted: installed, secure, and tall enough. A territorial guardian that can leave the property is the fastest route to a bite incident involving someone with “incidental or no familiar relationship” to the dog, which was present in 85.2% of the fatality cases.[7] “We will fence it after the puppy arrives” is a no.

  3. 3. Do you have the daily hour, on the bad days?

    Here the published sources disagree and most breed pages quietly split the difference. Orvis says a healthy adult Boerboel needs “between one and two hours of physical activity and training each day.”[16] Dog Academy says “walks of half an hour to an hour are ideal.”[17] That looks like a fourfold gap until you read what each is counting: Orvis is counting activity plus training, Dog Academy is counting walks alone. Once you line the definitions up, the two mostly agree. Our own position, labelled as a position rather than dressed up as data: budget about an hour a day for an adult, roughly half of it walking and half of it training, yard work and structured play. The number that actually decides this is not the total. It is whether you will do it on the worst Tuesday in February.

  4. 4. Can you hold the feeding line for a decade?

    Overweight and obesity was the second most common disorder recorded in giant-breed dogs, at 8.02%.[1] A giant dog eats like a giant dog, and the daily volume surprises people who have only owned a Labrador. Worse, a Boerboel carrying an extra 15 pounds is loading the same stifles that already carry the highest cruciate risk of 181 breeds.[8] The arithmetic is on our cost of ownership page.

  5. 5. Are you signing up for about nine years, not fifteen?

    Median age at death across giant breeds was 8.94 years, IQR 6.96 to 10.9.[1] That is a different emotional contract from the twelve to fifteen years people assume when they buy a dog, and it is one of the two most common things buyers tell us they wish someone had said first. Our Boerboel lifespan page does the breed-level derivation properly.

  6. 6. Have you actually read your insurance policy and your lease?

    Not called your agent to ask casually. Read the restricted-breed language, in writing, before a deposit. Homeowners policies, renters policies, HOAs and municipalities all restrict large guardian breeds in ways that surface at the worst possible moment. Our guide to Boerboel bans, laws and insurance walks through exactly what to look for.

  7. 7. Does the entire household want this dog?

    Not tolerates. Wants. One adult enthusiastically training a guardian breed while another quietly resents it produces inconsistent rules, and inconsistent rules on a 170 pound dog produce a dog that makes its own. This one has no study attached and we are not going to invent one; it is simply the pattern we see most often in the placements that go sideways.

  8. 8. Will an able-bodied adult be present whenever the dog is with anyone vulnerable?

    The single most common factor in 256 fatalities was the absence of an able-bodied person to intervene, at 87.1%.[7] This is not a Boerboel statistic, it is a dog statistic, and it is the cheapest safety measure that exists. If your household routinely leaves a dog unsupervised with small children or a frail adult, no breed on the giant list belongs in it. Children specifically, including age bands and the supervision protocol, are handled on are Boerboels good family dogs.

  9. 9. Is a trainer already lined up, by name?

    Not “we will find someone.” A named trainer with guardian-breed experience, contacted before the deposit. Failure to attend obedience classes after acquisition is one of the identified modifiable risk factors for relinquishment.[9] A first-time owner without a trainer is the profile that ends with a two-year-old dog nobody can place.

What the first two years actually demand

Almost every “is this breed for beginners” page stops at temperament adjectives. The useful version is a timeline, because the work is not evenly distributed and the expensive mistakes are front-loaded.

Weeks 3 to 12: the window that does not reopen

The AVSAB is unambiguous that the primary and most important time for puppy socialization is the first three months of life, and that incomplete socialization during it increases the risk of fear, avoidance and aggression later.[12] Note what that means for the calendar: a puppy typically goes home at eight weeks, so a large part of the window is already spent before you have the dog, and what is left is roughly four weeks in which a first-time owner has to do the most consequential work of the dog’s life while also housetraining it. This is the one item on the page that cannot be fixed later with effort or money. The depth version, including what the evidence does and does not support, is on our temperament page.

Months 8 to 18: the guarding switch

The friendly puppy that greeted everyone starts having opinions about the delivery driver. This is the breed arriving on schedule, not a training failure, and the AKC’s own description of the Boerboel as an “intimidating but discerning” guardian that is “dominant and confident” is exactly the trait switching on.[19] What separates a good outcome from a bad one here is whether the owner has already installed the management vocabulary, a reliable place command, a reliable recall, a routine for visitors, before the opinions arrive. First-time owners almost always start installing it afterwards, which is training against a dog that has already had a vote.

Months 12 to 24: the neuter decision, and an honest contradiction

Two good pieces of evidence pull in opposite directions here and you deserve both rather than a tidy answer. Hart and colleagues, working with mixed-breed dogs across five weight categories, recommend delaying neutering of males in the heaviest category to about two years, because neutering before one year was associated with joint-disorder risk commonly around three times that of intact dogs.[11] Against that, in the 256-fatality study 84.4% of the dogs were not neutered.[7] Those two findings do not resolve into a rule. Our read, offered as a read: the Hart guidance is about joint outcomes in a dog you are going to manage well, and the Patronek figure sits inside a stack of other factors, isolation and lack of supervision among them, that describe dogs nobody was managing at all. If you can genuinely contain and supervise an intact adolescent male guardian for two years, the joint argument is strong. If you cannot, that is information about the neutering date and also about whether this is your breed. Decide it with your vet, with both papers on the table.

Months 0 to 18: growth plates, and the exercise you must not do

Growth plates stay open far longer in giant breeds than new owners expect, into the 18 to 24 month range, and strenuous loading before they close can injure them.[13] The counterintuitive part for a new owner is that the correct answer to a big energetic puppy is usually less structured exercise, not more: free play on grass where the puppy sets its own pace, rather than jogging, stairs and repeated jumping. Given that this breed already carries the highest cruciate relative risk of 181 breeds[8], the joints you protect during growth are the ones you are not paying a surgeon for later. Our Boerboel growth chart has the weight-by-age numbers and the safe-exercise limits.

Somewhere between months 9 and 12: the dog outweighs the person walking it

This is the moment worth putting a date on, because households rarely notice it until it matters. Our own growth figures put a male at 100 to 145 lbs at nine months and 120 to 170 lbs at twelve, so he passes the body weight of most adults in the house while he is still an adolescent, long before he is finished growing. From that point on, leash handling stops being a matter of strength and becomes entirely a matter of training that is already installed. If the plan involves a teenager or an older relative walking the dog, run the numbers against the growth chart and decide now, not then.

The one exception, and its conditions

There is a first-time owner who does well with this breed. We have placed dogs with them. But the exception is narrow enough to name, and it comes with conditions rather than with encouragement.

The prepared novice: first dog of their own, but not their first large dog

This is someone who has handled large or working breeds without having owned one: grew up with them, worked at a boarding kennel or a shelter, volunteers with a rescue, trains at a club. They are a first-time owner. They are not a first-time handler, and that distinction is where the 91% lives.

All five conditions, not three of five:

  • A named trainer with guardian-breed experience, engaged before the deposit.
  • Secure fencing already installed, not planned.
  • Insurance and lease or HOA language read in writing, and clear.
  • An adult home for most of the day through the first year.
  • Every adult in the household actively wants the dog.

Notice what is not on that list: enthusiasm, research, having watched a lot of videos, or loving the breed. Those are all real and none of them is a qualification. Notice also that four of the five conditions are things you can arrange in a year. That is the point. For most people the honest answer is not yet, and “not yet” has a schedule.

Who the breed is for

A page that only says no is not honest either. The Boerboel is a superb dog in the right home, and the right home is describable. It looks like this:

  • Prior experience with a large or working breed, whether or not the dog was legally yours.
  • A trainer already lined up who has worked with guardian breeds specifically, not just with pet dogs.
  • Secure fencing already in place, and enough yard for a heavy dog to patrol and move.
  • No rental, HOA or insurance restriction, verified in writing rather than assumed (see bans, laws and insurance).
  • An adult home most of the day, especially through the first year. This breed was developed to live with its family, not beside it.[19]
  • No small children under roughly five, for reasons of physics rather than temperament. The age bands, the supervision protocol and the visiting-children question are handled properly on are Boerboels good family dogs.
  • You want a guardian, and you are clear-eyed about it. If what you want is a dog that likes everybody, this breed will disappoint you by succeeding at its job.

Why a breeder would rather lose the sale

We turn down buyers who do not fit. That sentence appears on a lot of kennel websites, so here is the part that makes it credible rather than decorative: a bad placement costs us more than a lost sale does. A lost sale costs one deposit. A bad placement produces a two-year-old dog that comes back to us, or worse, one that does not and becomes somebody’s story about the breed. We take our dogs back for life, which is the only version of a guarantee that means anything, and that liability is priced into how selective we are at the front end.

So if you apply and we tell you to spend a year with large dogs and come back, that is not a soft no. It is the same advice we would give a friend, and the people who take it come back as the buyers we most want to sell to.

If the answer is no: what to get instead

“Get a different breed” is more useful advice than “buy our puppy,” so here is the version with measured numbers attached. The medians below come from the Dogs Trust life expectancy table built on 584,734 UK dogs across 155 breeds, which is the largest dataset of its kind.[14, 15] Compare them against the 8.94-year median age at death across giant breeds.[1]

Median life expectancy of alternative breeds, from the Dogs Trust 155-breed table
BreedMedian life expectancy95% CInWhy it is on this list
Rottweiler10.6 yrs10.4-10.76,275Most of the deterrent, a fraction of the mass, and a far deeper pool of trainers who know the breed.
Doberman Pinscher11.2 yrs11.0-11.53,531Highly trainable, physically manageable, still visibly a guardian. Cardiac screening is the homework here.
Boxer11.3 yrs11.3-11.511,294Family-first temperament with a real bark. Less guarding drive to manage.
German Shepherd Dog11.3 yrs11.3-11.419,908The most training infrastructure of any breed on this list. Needs a job, not just a yard.
Rhodesian Ridgeback12.0 yrs11.9-12.22,108Aloof, athletic, independent. Closest in feel to a Boerboel at roughly half the weight.
Labrador Retriever13.1 yrs13.0-13.143,428Not a guardian at all. If you mostly want a family dog, be honest about that.
Poodle14.0 yrs13.8-14.16,427Longest-lived on this list. Listed in the table as one breed, without splitting by variety.

Medians, confidence intervals and sample sizes are taken directly from the published table.[15] The table lists “Poodle” as a single row without splitting by variety, so we have not split it either.

The direct recommendation. If what you want is a protective family dog and this is your first dog, a Rottweiler or a German Shepherd Dog gives you most of the deterrent at a fraction of the weight and one to two more years of life, plus something a Boerboel cannot offer a beginner: a deep bench of trainers, clubs and rescues who already know the breed inside out. If you want the Boerboel’s aloof, athletic, independent feel at roughly half the mass, look at the Rhodesian Ridgeback at a 12.0-year median. And if you are honest with yourself and what you actually want is a family dog rather than a guardian, the Labrador Retriever at 13.1 years asks less of you in every direction.

The work-up-to-it path

If the Boerboel is the dog you actually want, the route is not to buy one now with good intentions. It is: get a Rottweiler, a Shepherd or a Ridgeback first and raise it properly through adolescence, or spend a year handling large dogs through a rescue, a club or a boarding kennel. Then come back. You will arrive with a trained eye, a relationship with a trainer and a realistic sense of what an 80 pound adolescent does when it disagrees with you, which is exactly the experience the 91% is made of.[6] We would rather place a dog with you in three years than sell you one this month.

For side-by-side detail, see Boerboel vs Rottweiler and Boerboel vs German Shepherd. If you are choosing a breeder rather than a breed, our guide to how to choose a Boerboel breeder covers what to demand, and male vs female Boerboel covers the sex question in full.

First-Time Boerboel Owner FAQ

Is a Boerboel a good first dog?

For most first-time dog owners, no. A Boerboel is a guardian breed whose males run 150 to 200 pounds, and in a UK veterinary study of 29 giant breeds aggression was recorded as a clinical disorder in 5.56 percent of dogs in a single year, more than double the 2.24 percent recorded across dogs overall. Research also shows breed explains only about 9 percent of a dog's behaviour, which means roughly 91 percent of the outcome is the owner's training, socialization and management. A first-time owner is being asked to supply the 91 percent with no practice.

Are Boerboels very difficult to handle for first-time dog owners?

Yes, and the difficulty is physical as well as behavioural. A Boerboel male commonly reaches 150 to 200 pounds, which means that from roughly twelve months of age the dog can out-pull an average adult on a leash whenever it decides to. The behavioural difficulty is that a guardian breed defaults to making its own decisions about strangers unless it has been taught otherwise, so an inexperienced handler is usually late rather than wrong. Difficulty is not the same as danger, but it does mean that mistakes get expensive faster than they would with a 40 pound dog.

What are some real-life challenges of owning a Boerboel that new owners might not expect?

Four surprise most new owners. First, the cost of orthopaedic surgery: in a Swedish study of over 600,000 insured dogs, the Boerboel had the highest relative risk of cruciate ligament rupture of 181 breeds at 11.0. Second, feeding discipline, since overweight and obesity was recorded in 8.02 percent of giant-breed dogs in one year. Third, the commitment is shorter than expected, with a median age at death of 8.94 years across giant breeds rather than the twelve to fifteen years people assume. Fourth, insurance and rental restrictions, which are often discovered after the puppy is already home.

Can I get a Boerboel if I have never had a big dog?

It is possible but it is the hard route, and most people who try it should not. The realistic version is that you build the missing experience first rather than on the dog: work with large breeds through a rescue, a boarding kennel or a training club for a year, line up a trainer experienced with guardian breeds before you ever put down a deposit, and have secure fencing already in place. If you are not willing to do those three things before the puppy exists, the honest answer is that you are not ready for this breed yet.

Is a female Boerboel easier for a first-time owner?

Somewhat, mostly because of size. Females commonly run 120 to 170 pounds against 150 to 200 for males, so a female is easier to physically control on a leash and in the house. That is a real advantage but it is not a qualification: a 140 pound female guardian still requires the same socialization, training and management as a male, and choosing a female does not convert an unprepared home into a prepared one.

What happens if I cannot handle him at two years old?

That is the question worth asking before you buy, because two years old is exactly when it happens. The usual answer is that the dog is rehomed, and rehoming an adult guardian breed is hard: the pool of qualified homes is small and shrinks further once there is any bite history. Research on shelter relinquishment identified the modifiable risk factors as not attending obedience classes after acquisition, little or no veterinary care, keeping a sexually intact dog and inappropriate care expectations, all of which are decisions made in the first year. A responsible breeder should also take the dog back rather than let it enter a shelter, so ask any breeder that question in writing before you buy.

What dog should I get instead if a Boerboel is too much?

If you want a protective family dog and this is your first dog, a Rottweiler or a German Shepherd Dog gives you most of the deterrent at a fraction of the weight and one to two more years of life. In the Dogs Trust life expectancy table the median is 10.6 years for the Rottweiler and 11.3 for the German Shepherd Dog, against 8.94 years as the median age at death across giant breeds. If what you actually want is a family dog rather than a guardian, a Labrador Retriever has a median of 13.1 years and asks far less of a first-time owner.

Last reviewed August 2026. The giant-breed figures describe 29 giant breeds as a group; we could not retrieve the study’s breed list and do not claim the Boerboel is among them. Where a statement is our kennel’s position rather than a published finding, we have labelled it as such on the page.

Still think this is your breed?

Then tell us the truth on the application and let us argue with you about it. We would rather spend an hour talking you out of a Boerboel than ten years watching a placement fail.
