A Brussels Griffon owner thinking about supplements should focus on three things: a digestive system that swallows a lot of air thanks to that famous flat face, small kneecaps that can slip out of place, and a temperament so people-attached that stress can show up in the stool. Get those three right and you've covered most of what this breed is documented to need.
We're Super Snouts, and we make supplements for dogs whose owners read labels. Here's how we'd think through a Griff.
Breed snapshot: the bearded little shadow
The Brussels Griffon stands 7 to 10 inches tall, weighs 8 to 10 pounds, and comes in two coats — rough (wiry, bearded) and smooth. Bred in 19th-century Belgium to hunt rats in stables, the modern Griff has traded vermin for velcro. The AKC describes the breed as loyal, alert, and almost comically human in expression, with a life expectancy of 12 to 15 years.
Two anatomical facts drive most of this guide. First, the Griff is brachycephalic — that pushed-in muzzle changes how the dog breathes, eats, and regulates heat. Second, at under 10 pounds, this is a true toy breed, with the joint and dental quirks that come with miniaturization.
Why do flat-faced dogs have gassier stomachs?
Brachycephalic dogs tend to gulp air while eating and drinking. That swallowed air — vets call it aerophagia — has to go somewhere, and in many flat-faced breeds it exits as burping, flatulence, or a grumbly gut. Griffs that inhale their dinner in twenty seconds make it worse.
A few practical moves help. Slow-feeder bowls stretch a meal from seconds to minutes. Smaller, more frequent meals reduce the volume of air swallowed per sitting. And soluble fiber gives the gut something steady to work with: pumpkin is the classic here, which is why we built Pumpkin Latte around organic pumpkin, ginger, and slippery elm — ingredients traditionally used to soothe an unsettled stomach and support the gut lining.
When gas comes with soft stool, we reach for targeted probiotics and digestive enzymes instead. G.I. Balance combines both so the gut gets help breaking food down before it ferments into gas. If your Griff's digestion changes suddenly — new gas, new stool texture, new appetite — loop in your veterinarian before assuming it's just the flat face at work.
Are Brussels Griffons prone to knee problems?
Yes, and it's worth taking seriously in a breed this small. Patellar luxation — a kneecap that slides out of its groove — is one of the most common orthopedic issues in toy dogs, and the Griffon appears on most veterinary lists of predisposed breeds. VCA Animal Hospitals explains that severity is graded 1 through 4, and mild cases often show up as a hop-skip in the back leg that resolves after a few strides.
Surgery is a veterinary decision, not a supplement decision. But cartilage nutrition is something owners can start early. Green-lipped mussel from New Zealand carries a naturally occurring package of omega-3 fatty acids (including rare ETA), glucosamine, and chondroitin — the raw materials joints use. Our Joint Power is nothing but that one ingredient, freeze-dried, because we'd rather give a 9-pound dog a concentrated whole-food source than a long ingredient panel of fillers. If you ever see your Griff skip, bunny-hop, or hold a rear leg up, book a vet exam — grading the knee early gives you the most options.
Keeping a Griff lean matters just as much. Every extra ounce on an 8-pound frame loads those tiny stifles disproportionately.
The velcro problem: stress and the Griffon gut
Griffs bond hard. Breed clubs are blunt that this is not a dog who thrives on eight hours of alone time, and separation distress in the breed is well documented anecdotally and in temperament literature. Stress isn't just behavioral — the gut-brain axis means an anxious dog often becomes a dog with loose stool.
We'd approach this on two fronts. Behaviorally: gradual alone-time training, enrichment feeders, and predictable routines, ideally with guidance from your vet or a certified trainer. Nutritionally: Lion's Roar delivers lion's mane mushroom, a nootropic fungus studied for nervous-system support, as a non-drowsy daily option. For dogs who need more situational help — thunderstorms, travel, long absences — our hemp-based Chill + Out chews exist for exactly that, though we'd suggest discussing hemp products with your veterinarian first, especially for a small dog on other medications.
How we'd build a Brussels Griffon supplement routine
Start with one product, not four. More jars doesn't mean better results — it means you can't tell what's working.
- Weeks 1–4: gut foundation. Daily probiotic and enzyme support with G.I. Balance, plus a slow feeder. Watch stool quality and gas.
- Weeks 4–8: add joint support. Layer in Joint Power once digestion is stable. Green-lipped mussel is food-based, so most small dogs accept it readily.
- As needed: stool and stress tools. Keep Firm Up! — our pumpkin-and-apple-fiber blend — on hand for the occasional soft-stool day, and consider Lion's Mane support if alone-time stress is part of your Griff's story.
Dose everything to the low end of the label for a sub-10-pound dog, and run any new supplement past your veterinarian if your Griffon has an existing diagnosis or takes medication.
Frequently asked questions
What supplements does a Brussels Griffon actually need?
Most Griffs benefit from digestive support (probiotics, enzymes, soluble fiber) because of air-gulping and small-breed stomach sensitivity, plus early joint support given the breed's documented patellar luxation risk. Calming support is situational. Your vet can help you prioritize based on your individual dog.
Why does my Griffon have so much gas?
Flat-faced breeds swallow extra air when eating and drinking, and fast eaters swallow the most. Slow feeders, smaller meals, and enzyme-plus-probiotic support usually reduce it noticeably. Sudden or severe gas changes deserve a veterinary look.
When should I start joint supplements for a toy breed?
There's no single right age, but breeds predisposed to luxating patellas are reasonable candidates for early cartilage nutrition — many owners start around 12 months. Ask your veterinarian to check your Griff's knees at routine visits so you have a baseline.
Can I give my Griffon pumpkin every day?
Plain pumpkin in small amounts is generally well tolerated daily and is a solid soluble-fiber source. A measured supplement makes dosing consistent for a tiny dog. Check with your vet if your Griff has diabetes or is on a prescription diet.
The short version
A Brussels Griffon is a big personality riding around in a small, flat-faced, tightly bonded package. Support the gut first, protect the knees early, take alone-time stress seriously, and keep your veterinarian in the loop on anything new — supplements included. That's the whole playbook, and it's a manageable one.
