SABBS & AKC / American Boerboel Club
Think of this as a comprehensive educational guide, explaining both breed standards, where they agree, where they differ, and why those differences matter to breeders and owners.
The important distinction is that SABBS and AKC share the fundamental goal of preserving a correct, functional Boerboel, but they do not use identical evaluation systems.
SABBS uses a formal appraisal system to evaluate individual Boerboels against its breed standard, while the AKC uses the standard established through the American Boerboel Club to judge dogs in conformation competition. SABBS +1
Understanding the Boerboel Breed Standards
SABBS and AKC: Preserving the Boerboel’s Type, Temperament, Structure, and Purpose
By Black Iron Boerboels
Introduction: Understanding What Makes a Correct Boerboel
I’ve spent nearly four decades breeding dogs, and since bringing our first Boerboel into the United States in 2014, I’ve had the opportunity to work with, raise, breed, and evaluate multiple generations of this incredible breed.
One thing I’ve learned is that there is a tremendous difference between a Boerboel that looks impressive and one that is actually correct.
The Boerboel is not supposed to be the biggest dog in the room. It isn’t supposed to have the largest head, the heaviest bone, or the most exaggerated chest. Those characteristics may attract attention, but they do not necessarily make a dog a good representation of the breed.
A correct Boerboel must possess the temperament, structure, balance, athletic ability, and physical characteristics that allow it to perform the job it was developed to do.
There are two important standards that Boerboel owners and breeders in the United States should understand: the standard established by the South African Boerboel Breeders’ Society (SABBS) and the AKC standard maintained through the American Boerboel Club (ABC).
Although the two standards share many fundamental principles, there are differences in their wording, specific requirements, and methods of evaluation.
Understanding those differences is important, particularly for breeders who participate in both SABBS appraisals and AKC conformation events.
Neither standard should be viewed as an excuse to select for exaggerated characteristics. Both recognize the importance of a Boerboel that is physically capable, mentally stable, and unmistakable in breed type.
1. The History and Purpose of the Boerboel
Before discussing either standard, we need to understand why the Boerboel exists.
The Boerboel developed in South Africa as a working farm dog. These dogs were expected to protect families, livestock, and property under conditions that demanded strength, courage, intelligence, and physical endurance.
They had to be powerful enough to confront serious threats while remaining agile enough to move efficiently across farms and challenging terrain.
They also needed the judgment to distinguish between ordinary activity and an actual threat.
That is a critical part of the breed’s identity.
A Boerboel that is indiscriminately aggressive, fearful, structurally unsound, or physically incapable of sustained movement is not fulfilling the original purpose of the breed.
Both SABBS and AKC recognize that a Boerboel’s physical characteristics and temperament must support its function.
My perspective: If we lose the working ability, soundness, and stable temperament of the Boerboel in pursuit of size or appearance, we are moving away from the breed rather than improving it.
2. Understanding SABBS and the AKC
The South African Boerboel Breeders’ Society is a South African breed society responsible for maintaining the Boerboel’s breed standard and its system of appraisal, registration, and breed improvement.
The American Boerboel Club is the official AKC parent club for the Boerboel in the United States.
The standards share the same historical foundation, but their evaluation systems are different.
SABBS Appraisal
SABBS evaluates individual dogs through a formal appraisal process. Appraisers examine physical characteristics, breed type, structure, movement, and other relevant qualities using an official appraisal chart.
Dogs receive a numerical appraisal score based on the assessment. That score provides a record of the dog’s evaluation against the SABBS system.
A dog may be presented for standard appraisal at 12 months, although SABBS recommends approximately 18 months because the dog is more physically mature.
SABBS appraisal and registration requirements are governed by its current constitution and bylaws.
AKC Conformation
AKC conformation evaluates dogs against the written breed standard established through the American Boerboel Club.
Dogs compete against others, with judges evaluating how closely each dog represents the breed ideal.
Unlike SABBS, AKC conformation does not normally assign a numerical percentage that represents the dog’s overall conformity to the standard.
An AKC championship and a SABBS appraisal score therefore represent different achievements.
A dog can be highly successful in one system without necessarily receiving an equally outstanding evaluation in the other.
I believe both systems can provide useful information when their purposes and limitations are properly understood.
3. General Appearance: Strength Without Exaggeration
Both standards describe the Boerboel as a large, powerful, muscular dog with an imposing appearance.
However, neither standard supports sacrificing function for exaggerated size or substance.
SABBS emphasizes a strong-boned, well-muscled dog with balanced proportions, powerful movement, and distinct masculine or feminine characteristics.
The AKC similarly emphasizes strength, confidence, muscular development, agility, and functional efficiency.
In both systems, the dog should appear capable of performing demanding physical work.
A correct Boerboel should have substance without becoming cumbersome.
It should have a powerful head without that head being disproportionate to the body.
It should have substantial bone without weak pasterns or compromised movement.
And it should have a broad, muscular body supported by correctly constructed front and rear assemblies.
My perspective: There is nothing wrong with a large, substantial Boerboel. The problem begins when size and substance are pursued at the expense of balance, soundness, and mobility.
4. Height, Proportion, and Substance
This is one area where the two standards express their expectations differently.
SABBS
The SABBS standard identifies an ideal height of approximately 66 cm for males and 61 cm for females, with minimum heights of 60 cm and 55 cm respectively.
The standard also addresses the relationship between height, mass, and overall body proportions.
The body should be approximately 10–15% longer than the dog’s height at the withers.
AKC
The AKC standard identifies preferred heights of 24–27 inches for males and 22–25 inches for females.
The ideal relationship between body length and height is approximately 10:9.
The AKC specifically emphasizes that balance, proportion, and sound movement are more important than size.
What this means
Both standards describe a Boerboel that is slightly longer than it is tall.
Both expect males to demonstrate greater substance and distinctly masculine characteristics, while females should be feminine without appearing weak.
Neither standard should be interpreted as encouraging excessive weight or height.
I would much rather see a balanced Boerboel with correct structure and excellent movement than an oversized dog that struggles to carry its own mass.
5. The Head: A Defining Characteristic of the Boerboel
The head is one of the most recognizable features of the breed.
Both standards describe a powerful, broad, deep head with well-developed musculature and strong jaws.
SABBS
The SABBS standard places considerable emphasis on the characteristic cube-shaped head, with specific relationships between skull dimensions and muzzle length.
The head should be proportionate to the body, with well-developed cheeks, appropriate skull width, and a strong, broad muzzle.
AKC
The AKC standard describes a broad, deep, square, muscular head with well-filled cheeks.
The muzzle should be slightly longer than one-third of the total head length, with the skull and muzzle on nearly parallel planes.
What this means
Both standards recognize the head as an important component of breed type.
However, an enormous head is not automatically a correct head.
A Boerboel can have tremendous head circumference and still possess incorrect proportions, poor muzzle construction, excessive flews, or other structural weaknesses.
The head must complement the rest of the dog.
My perspective: I appreciate a powerful Boerboel head as much as anyone, but I am far more interested in a correct head than simply a large one.
6. Eyes, Ears, Bite, and Expression
The facial characteristics of the Boerboel contribute significantly to breed type and expression.
Both standards call for appropriately placed ears, strong jaws, and an intelligent, attentive expression.
The ears should be medium-sized, V-shaped, and carried close to the head.
The eyes should be appropriately sized and positioned, with sound eyelid construction.
There are some important differences between the standards.
The SABBS standard permits eye colors ranging through shades of yellow and brown, while the AKC prefers dark brown eyes and identifies yellow, bird-of-prey-type eyes as a serious fault.
The AKC disqualifies blue eyes, entropion, ectropion, prick ears, overshot bites, wry mouths, and undershot bites exceeding 1/4 inch.
The standards also differ in some details of preferred bite and dental evaluation.
These differences matter when presenting dogs for appraisal or competition.
A feature acceptable under one system should not automatically be assumed to receive the same treatment under the other.
7. The Front Assembly: More Than a Broad Chest
The front assembly is one of the most important areas of structural evaluation.
A Boerboel is a substantial dog. Its front assembly must support that weight while allowing efficient movement.
Both standards emphasize strong bone, muscular shoulders, proper elbow placement, strong pasterns, and correct feet.
The shoulders should have appropriate angulation, with the upper arm and shoulder blade working together to produce effective front reach.
The forelegs should be straight and correctly aligned when viewed from the front.
Pasterns should be strong, with enough flexibility to absorb impact without collapsing.
The feet should be compact and well constructed.
A wide chest does not automatically indicate a correct front.
In fact, excessive width without proper shoulder and upper-arm construction can interfere with efficient movement.
My perspective: One of the mistakes people make when evaluating Boerboels is placing too much emphasis on chest width and not enough on the actual construction of the front assembly.
A dog can look tremendous standing still and demonstrate significant structural weaknesses as soon as it begins moving.
8. Topline, Body, and Overall Balance
Both standards describe a strong, muscular body with a firm topline, adequate chest depth, well-developed ribs, and a powerful loin.
The topline should remain stable during movement.
The back should not demonstrate excessive sway, weakness, or unnecessary movement.
The croup should be appropriately constructed and complement the overall body.
The ribcage should provide adequate depth and capacity without interfering with the front assembly.
A correct Boerboel should appear balanced from front to rear.
My perspective: I want a dog that looks as correct moving as it does standing.
A beautiful topline in a photograph means very little if that topline becomes unstable when the dog moves.
9. Hindquarters: Power Must Be Supported by Structure
The hindquarters provide much of the propulsion that allows a Boerboel to move efficiently.
Both standards call for powerful, muscular hindquarters with strong bone, well-developed thighs, sound stifles, and stable hocks.
Rear angulation should complement the front assembly.
A dog with excessive rear angulation and insufficient front angulation is not balanced.
Likewise, a dog with inadequate rear angulation may lack the drive expected of the breed.
Correct construction is not about producing the most dramatic silhouette.
It is about producing a dog whose front and rear assemblies function together.
My perspective: I want strength, stability, and coordinated movement. Excessive angulation should never be confused with superior structure.
10. Movement: Where the Truth Comes Out
Movement is one of the most revealing parts of evaluating any dog.
Both SABBS and AKC emphasize powerful, purposeful, balanced, and efficient movement.
The Boerboel should demonstrate sufficient front reach and strong rear drive without unnecessary effort.
The topline should remain stable.
The legs should move in a coordinated manner, with no crossing, significant interference, or excessive body roll.
The AKC specifically identifies movement as the ultimate test of correct conformation.
SABBS also places substantial importance on movement and calls for significant penalties for weak, restricted, or unsound movement.
My perspective: You can hide a lot in a stacked photograph. You cannot hide nearly as much when a dog is moving.
Movement reveals structural weaknesses that may not be obvious when the dog is standing still.
A Boerboel should move like a capable working dog, not like an oversized mastiff struggling to get from one place to another.
11. Temperament: The Most Important Characteristic We Cannot Afford to Lose
Temperament is foundational to the Boerboel.
Both standards describe a confident, intelligent, protective dog that is loyal to its family.
SABBS
The SABBS standard emphasizes a Boerboel that is manageable, reliable, trainable, intelligent, self-confident, fearless, and protective.
The dog should demonstrate courage when threatened while remaining calm and balanced when approached.
Controllability is an important part of the breed’s character.
AKC
The AKC describes a dominant, intelligent dog with strong protective instincts and a willingness to please.
The dog should be calm, stable, and confident, sometimes demonstrating self-assured aloofness.
It should recognize whether a threat actually exists.
The AKC standard also acknowledges that aggression or belligerence toward other dogs should not automatically be faulted during breed evaluation.
That does not mean indiscriminate aggression or lack of control should be encouraged.
My perspective: There is a tremendous difference between a confident, protective Boerboel and a dog that is fearful, unstable, or reactive.
I do not believe a Boerboel should need to demonstrate aggression to prove that it is protective.
A stable guardian should have the confidence and judgment to recognize when a threat exists and when it does not.
That is the kind of temperament we should be preserving.
12. Coat, Color, and Pigmentation
Both standards recognize the importance of correct coat characteristics and pigmentation.
The Boerboel should have a short, dense, smooth coat.
Proper pigmentation is an important characteristic, particularly around the nose, eyes, lips, and other areas.
The AKC recognizes red, brown, reddish brown, fawn, cream, and brindle in accepted colors, along with certain permitted markings and patterns.
The AKC identifies specific color and pigmentation disqualifications, including blue or powder-coated dogs, unlisted base colors, long coats, and nose leather that is not black.
SABBS maintains its own color and pigmentation requirements, which must be evaluated according to its current breed standard rather than assuming the AKC rules apply.
My perspective: Color should never become more important than temperament, structure, health, or breed type.
Breeding primarily to produce a fashionable color is not the same as breeding to preserve or improve the Boerboel.
13. Understanding SABBS Appraisal Scores
One of the biggest differences between SABBS and AKC is how individual dogs are evaluated.
SABBS uses a detailed appraisal chart that assesses numerous characteristics of the dog.
The results are expressed as a numerical percentage.
This gives breeders an opportunity to review the dog’s individual strengths and weaknesses as recorded during the appraisal.
A dog receiving a score in the 90s has achieved a high numerical result within the SABBS appraisal system.
However, that score should never be treated as proof that the dog is perfect.
It is an evaluation of the individual dog at a particular time, under a specific system.
It is not a genetic guarantee, a comprehensive health clearance, or proof that the dog will consistently reproduce its own strengths.
I have been fortunate to own and breed Boerboels that have achieved exceptional SABBS appraisal scores, including Klein Sandfontein Judge and Black Iron Bentley.
Those achievements are meaningful to me because they reflect years of dedication to understanding and preserving the breed.
But I also understand that an appraisal score is one part of evaluating a breeding dog.
My perspective: A high appraisal score is something to be proud of, but it should never replace an honest assessment of the dog’s health, temperament, pedigree, reproductive history, and ability to produce quality offspring.
14. AKC Championships and SABBS Appraisals Are Not the Same Thing
An AKC championship demonstrates success in conformation competition under AKC rules.
A SABBS appraisal score represents an individual evaluation under the SABBS system.
They are different measurements and should not be presented as interchangeable.
An AKC champion has not necessarily received a SABBS appraisal.
A Boerboel with an outstanding SABBS appraisal score has not necessarily earned an AKC championship.
Both accomplishments can have value.
But neither should be used as a substitute for understanding the individual dog.
I believe breeders should be able to explain what each achievement represents rather than relying on titles or percentages to speak for themselves.
15. Health Testing and Responsible Breeding
Neither an AKC championship nor a high SABBS appraisal score guarantees that a dog is genetically or physically healthy.
That is an important distinction.
A Boerboel may demonstrate outstanding breed type and structure while still having orthopedic, cardiac, reproductive, or other health concerns.
SABBS has specific health documentation requirements associated with certain registration categories, including requirements addressing hip and elbow dysplasia and vaginal hyperplasia.
Responsible breeders should also evaluate health concerns beyond the minimum requirements of a registry.
For me, evaluating a breeding dog means looking at the complete picture.
That includes the dog’s physical characteristics, temperament, health testing, pedigree, family history, and what the dog has demonstrated through its offspring.
A beautiful dog with a high appraisal score is not automatically the right breeding candidate.
A successful show dog is not automatically the right breeding candidate either.
The goal should be to make decisions that improve the next generation.
16. Why Breeders Should Understand Both Standards
I believe breeders who work with Boerboels in the United States benefit from understanding both the SABBS and AKC standards.
SABBS provides a structured individual appraisal process rooted in the breed’s South African heritage.
AKC provides a conformation system that evaluates dogs against the standard maintained by the American Boerboel Club.
Understanding both can help breeders recognize strengths and weaknesses that might otherwise be overlooked.
However, we should not breed simply to chase a higher appraisal percentage or accumulate show titles.
Those accomplishments should reflect the quality of the dogs we are producing, not become the sole purpose of our breeding programs.
We also need to remember that judges and appraisers are human.
Evaluations involve professional judgment, and individual assessments can vary.
That is another reason breeders must develop their own understanding of correct structure, movement, temperament, and breed type.
17. Preserving the Boerboel Instead of Following Trends
The Boerboel has become increasingly popular, and with popularity comes the temptation to breed for characteristics that attract attention.
We see dogs advertised because of their enormous heads, exceptional weight, extreme bone, unusual colors, or intimidating appearance.
But those characteristics do not necessarily represent improvement.
A Boerboel should never become so exaggerated that it loses the athleticism and physical ability that helped define the breed.
Nor should we compromise temperament in pursuit of a dog that appears more intimidating.
The Boerboel was developed as a capable, dependable working guardian.
That purpose should remain central to our breeding decisions.
We have a responsibility to preserve the qualities that made this breed exceptional in the first place.
Final Thoughts: The Complete Boerboel
After all these years, I still believe the most important thing a breeder can do is learn to evaluate dogs honestly.
Every Boerboel has strengths and weaknesses.
Even the best dogs have areas that could be improved.
Understanding the SABBS and AKC standards gives us a foundation for recognizing those characteristics and making more informed breeding decisions.
But the standards are only as valuable as our willingness to apply them.
A massive head does not compensate for poor movement.
Exceptional substance does not compensate for structural weakness.
An impressive pedigree does not compensate for unstable temperament.
And neither a high appraisal score nor an AKC championship should prevent us from recognizing a dog’s faults.
At Black Iron Boerboels, our philosophy centers on Temperament, Power, Presence, and Substance.
I believe those qualities should complement one another, never compete with one another.
The Boerboel should be powerful but athletic, substantial but balanced, protective but mentally stable, and impressive without being exaggerated.
Our responsibility is not simply to produce Boerboels that look the part.
It is to preserve the characteristics that make them Boerboels.
Because a truly exceptional Boerboel isn’t defined by one outstanding characteristic. It is the complete dog that matters.
