If you share your home with a Boerboel, your dental priorities are protecting teeth from your dog's own bite force and keeping the jowly, deep-lipped mastiff mouth clean where it traps food and moisture. This South African farm guardian rarely suffers the crowding problems of small dogs — its challenges are mechanical force, lip-fold hygiene, and the sheer difficulty of noticing problems inside a very large, very composed dog.
We've formulated dental chews at Ark Naturals for over 25 years, all made in the USA, and mastiff-type dogs taught us early that chew texture isn't a preference question — it's a safety one.
What a mastiff head means for teeth
The Boerboel ("farmer's dog" in Afrikaans) was developed to protect South African homesteads, and everything about the head announces it: a broad, blocky skull, a deep and wide muzzle, and a body that commonly runs 150 to 200 pounds. The breed standard accepts a scissors bite and tolerates a slightly undershot jaw, so some Boerboels carry their lower incisors a touch ahead of the uppers — usually a cosmetic quirk, though more pronounced misalignments can cause teeth to strike soft tissue and deserve a veterinary opinion.
Those wide jaws generate crushing force that most chew products were never engineered to meet. A Boerboel can shear pieces off "durable" toys, crack marrow bones lengthwise, and — the part owners learn the hard way — fracture its own premolars in the process.
The mouth's other defining feature is soft tissue. Boerboels have fleshy, pendulous lips and jowls that create warm, damp folds where food particles, saliva, and bacteria settle. Odor blamed on "dog breath" is often actually lip-fold buildup — or the two problems feeding each other.
The dental risks that come with the territory
Slab fractures of the carnassial teeth. The signature giant-breed injury: a flat chip sheared off the upper fourth premolar by biting down on something unyielding. Exposed pulp means pain and infection risk even when the dog eats normally, which a stoic Boerboel will.
Periodontal disease behind heavy lips. Deep lips hide the gumline completely. Plaque hardens to tartar in days, gingivitis follows, and the American Veterinary Dental College notes the destructive phase happens below the gumline where owners can't see it at all. In a mastiff mouth, you have to go looking.
Lip-fold dermatitis. Chronic moisture in the folds can inflame skin, compounding oral bacteria and odor. It's adjacent to dental care but managed with the same daily attention.
Gulped chew fragments. A mouth this size can swallow chunks other dogs would have to chew. Any chew for a Boerboel must be sized for giants and supervised until you know your dog's chewing style.
A daily plan scaled to a 180-pound dog
Brush with the lip as your handle. Slide the toothbrush under those heavy flews rather than trying to open the mouth. Dog-specific enzymatic toothpaste, outer surfaces of the upper cheek teeth, thirty to sixty seconds a side. Most Boerboels, socialized well, tolerate this better than owners expect — they were bred to be handled by their families. Daily is the goal; your veterinarian can demonstrate proper gumline angle if you're starting fresh.
Choose chews by texture, not toughness. Marketing aimed at "power chewers" pushes ever-harder products, which is exactly backwards for fracture risk. We went the other way: our Soft Shield Protection+ chews use a soft, yielding texture that lets teeth sink in and get wiped clean, with Asta-Shield — astaxanthin, an antioxidant with peer-reviewed research — in the formula. No artificial flavors or colors, made in the USA, appropriate from 12 weeks of age, and available in sizes that give a giant jaw something to actually work on. Our DENTA-METER positions Soft Shield at the advanced-protection end; if you want to start simpler, our Brushless Toothpaste and Soft Brushless options are in the shop all dogs collection, and the full product range is here.
Wipe the folds. Once a day, run a damp cloth through the lip folds and dry them. This single habit removes a major bacteria reservoir, tames odor, and gives you a daily excuse to glance at the gums.
Watch water intake spots. Jowly dogs slop water, and the chin stays wet. A quick towel-off after drinking keeps the chin and lower lip folds healthier.
Weigh the chew rule. Nothing harder than what a fingernail can dent: no antlers, no hooves, no weight-bearing bones, no rock-hard nylon. With a Boerboel's bite force, that rule is doing heavy lifting.
Signs your Boerboel needs a veterinary dental exam
- Foul breath that persists after lip folds are cleaned
- A chipped or discolored tooth — gray or purple means the pulp may be dying
- Bleeding at the gumline, or gums that look angry red under the flews
- One-sided chewing, food dropping, or new caution with toys
- Facial swelling, especially below an eye
- Pawing at the mouth or head-shyness in a previously relaxed dog
Mastiff-type breeds are famously understated about pain, so don't wait for obvious distress. The AVMA recommends regular professional oral exams, and your veterinarian can tell you when a full cleaning under anesthesia makes sense for your individual dog — modern anesthetic monitoring handles giant breeds routinely, and it's the only route to the tartar below the gums.
Boerboel owners ask us
My Boerboel has a slightly undershot bite. Is that a dental problem?
Often it's just breed-standard variation with no health consequence. The concern is when misaligned teeth strike the palate or lips, or when the misalignment traps debris. Have your veterinarian assess the bite once during young adulthood so you know which camp your dog is in.
What can a Boerboel safely chew?
Flexible, giant-size dental chews and rubber toys with give. The dent-it-with-a-fingernail test is the quickest screen — if you can't, the tooth may lose the contest. Supervise new chews until you've confirmed your dog chews rather than bolts them.
Is bad breath normal for jowly breeds?
Mild dog breath, sure — but persistent foul odor is a symptom, not a personality trait. Clean and dry the lip folds first; if the smell survives that, the source is likely dental and warrants a veterinary look.
How early should dental care start for a Boerboel puppy?
From day one for handling, and 12 weeks for chews like ours. A 25-pound puppy that learns to enjoy mouth care becomes a 180-pound adult you can actually brush — the training window is the single best dental investment this breed offers. Your vet can check teething progress at each puppy visit.
