Should you choose a male or female Boerboel?
Choose the individual dog whose size, behavior and needs fit your household. A female may suit someone who prefers a smaller frame; a male may suit someone comfortable with the larger frame described in the breed standard. Neither choice supplies a ready-made personality or removes the need to assess the dog in front of you.
That recommendation rests on two different kinds of evidence: the AKC standard documents physical differences, while research across many dogs finds limited predictive value in sex for most surveyed behaviors. Treat those as separate findings. A measured height range does not establish which puppy will be more affectionate, obedient or comfortable with visitors.
If you already have a dog, start with compatibility rather than a preference for a boy or girl. That changes the question from “Which sex is better?” to “Can these particular dogs live together?”
Male vs female Boerboel size
| AKC preferred adult height | Male | Female |
|---|---|---|
| Inches at the shoulder | 24 to 27 | 22 to 25 |
| Centimeters, rounded | 61 to 69 | 56 to 64 |
The inch figures come from the AKC Official Standard of the Boerboel. The centimeter figures are conversions using 2.54 cm per inch. These are preferred conformation ranges, not a promise about a particular puppy. The standard describes males as having a larger frame and heavier bone, while placing more importance on balance and sound movement than sheer size.
For weight estimates, SABBS's separate metric ideals and growth information, use our Boerboel size and growth guide. Keep those different measures distinct when comparing a breeder's paperwork.
Before choosing, make your own handling checklist. Can the adults who will walk the dog manage that individual comfortably? Does your vehicle have suitable space? Where will the dog rest when guests visit? Can you arrange help if you are injured or away? These are planning questions, not tests that produce a pass mark for one sex.
Are female Boerboels calmer or easier to train?
Do not treat either claim as an established rule. Morrill and colleagues' 2022 study in Science found that sex explained little of the variation in owner-reported behavior overall, with leg-lifting to urinate standing out as an exception. This was broad dog research, not a controlled comparison of male and female Boerboels. It does not prove the sexes behave identically, and it does not validate the familiar “easy female, stubborn male” formula. Read the original study.
Use that limitation constructively. Ask the breeder or rescue to describe this dog's behavior in specific situations instead of accepting a label such as “dominant” or “sweet.” Request examples: what happens when a visitor arrives, another dog passes, handling becomes unfamiliar, or an activity ends?
We recommend recording the answer, when it was observed, and what the caregiver did. “Settled behind a gate while a familiar visitor sat down” gives you something to discuss. “Females are always calmer” gives you no evidence about the candidate you might bring home.
Is a male or female Boerboel more protective?
The AKC describes protective characteristics in its breed temperament section without providing a separate male and female protection ranking. A standard describes an ideal; it cannot certify an individual dog's judgment or safety. AKC breed standard.
For a companion home, our recommendation is to prioritize manageable behavior around ordinary life: guests, deliveries, veterinary visits and family routines. Do not choose a puppy because someone presents aggressive reactions as proof of superior protection.
The RSPCA's aggression guidance explains that both sexes can show aggression and that context, learning and individual differences matter. If aggression is already a concern, arrange a veterinary assessment and qualified behavioral help. A sex-based label is not a diagnosis.
What if you already have another dog?
This is where sex deserves practical consideration. The Merck Veterinary Manual describes household dog aggression risk as highest in female/female pairs and lowest in male/female pairs. That is general veterinary guidance, not a Boerboel-specific probability for your home.
Take the Directory's same-sex pairing caution seriously. An opposite-sex candidate is a useful starting consideration, but lower relative risk does not establish that two individuals are compatible. The existing dog's history matters: explain prior conflicts and resource guarding to the professional helping with the introduction.
Plan for each dog to have its own space. The RSPCA recommends careful introductions and room for dogs to withdraw from one another. Ask for professional guidance before adding a dog if the resident dog is fearful of or aggressive toward other dogs.
For a household where conflict is a concern, Merck recommends environmental management and separation around resources that trigger aggression, such as meals or valued chews. Do not conduct a provocative “test” by putting the dogs together over food. Discuss the specific dogs and your ability to manage them before committing to a second one.
Does one sex need different training?
Use the same evidence-based foundation for both. The American Veterinary Society of Animal Behavior recommends reward-based methods for canine training and behavior work. Its guidance does not create an exception that requires intimidation for a large or challenging dog.
Our suggested starting priorities are everyday cooperation: walking with you, settling in a designated place, coming when called in appropriate practice settings, and comfortable handling. Ask a qualified reward-based trainer to adapt the plan to the dog's age, current skills and responses.
Budget for that support whether you choose a male or a female. The Boerboel training guide explains the foundation in more detail. Keep the purchase decision separate from a promise that one sex will require less work.
Include reproductive care in the decision
Discuss reproductive management before you commit. Ask whether the dog is intact or already sterilized, obtain its veterinary records, and review any relevant contract terms with your veterinarian.
The Australian Veterinary Association recommends deciding the procedure and timing case by case, considering the individual animal's risks and benefits. This article does not prescribe a universal surgery age. Merck also describes research on neutering and household dog aggression as inconclusive, so do not build a compatibility plan around a promise that surgery will fix conflict.
A practical checklist for choosing the individual dog
Use the same questions for every candidate. This is our decision aid, not a validated temperament test or a guarantee of future behavior.
- Describe your home in writing. Include resident animals, children, visitors, daily absences and who will handle the dog. Give the breeder or rescue the same information for each candidate.
- Ask for observations, with context. Request examples of the dog's response to routine handling, unfamiliar people and other dogs. Separate what someone has observed from what they expect.
- Discuss physical fit. Compare the individual dog's current size and family information with your handling and transport plans. Avoid choosing simply for the biggest promised adult.
- Review the records. Ask for identification, relevant health documents and the written agreement. Use our breeder-selection guide to organize that review.
- Resolve the second-dog question early. Arrange qualified guidance and a management plan before a deposit or adoption commitment. Write down what happens if an introduction does not go well.
- Allow yourself to wait. If the available dog's needs do not fit your home, keep looking. A preference for one sex is a reason to discuss options, not an obligation to accept an unsuitable match.
Make the final choice using those answers. Sex helps frame the size and pairing discussion; the individual dog's documented behavior and your realistic care plan should decide the match.
