Let me paint you a picture. You're standing at the pet store, staring down an entire aisle of dog products, and you're thinking: "Which of this stuff actually works for a 120-pound dog who thinks he's a lap dog?"
Been there. Three times, actually — because yes, I have three Bullmastiffs, and no, I don't have a normal amount of dog hair on my couch.
After years of trial, error, and one truly regrettable collar that lasted approximately four walks, here's what I've learned actually matters for this breed.
1. Collars & Walking Gear: Skip the Harness, Here's What Actually Works
Hot take incoming: I'm not a harness person. There, I said it.
For everyday wear and identification, I use wide collars on my Bullmastiffs — and I'm specifically a Boss Dog collar devotee. Here's why width matters: a standard narrow collar on a giant breed concentrates all that pressure into a thin band across the neck. A wide collar distributes it properly, which is far more comfortable for the dog and far less likely to cause any long-term issues.
But what sold me on Boss Dog beyond the width is the hardware. I have personally had standard black plastic buckle clips break while out with my dogs. Not "wear out over time" — break, in the moment, mid-walk. With a Bullmastiff on the other end of that leash, that's not a minor inconvenience. That's a safety incident. Boss Dog collars use superior metal hardware that actually holds up to what giant breeds put them through. As a bonus — they're a Seattle-based company, which as a fellow PNW dog lover makes me love them even more. You can shop their collar line at bossnationbrands.com.
For control and training, I use a Gentle Leader — not a harness. A Gentle Leader fits around the muzzle and the back of the head, and it works by guiding the direction of the dog's nose. Where the nose goes, the body follows. It gives you far more nuanced control over a powerful dog than a harness does, without any of the pressure or pulling dynamics. For a breed as strong and stubborn as a Bullmastiff, it's genuinely a game-changer.
On Amazon: Search PetSafe Gentle Leader Headcollar — it comes in sizes for large and giant breeds, and includes an instructional DVD for getting your dog comfortable wearing it (the intro period matters).
Pro tip: always pair your Gentle Leader with a backup — clip a standard leash to the collar as well until your dog is fully accustomed to it.
2. Food & Water Bowls: Slow It Down Before It Becomes a Vet Visit
I'm going to get personal here for a second, because this one matters more to me than any other item on this list.
I had a Bloodhound named Hemi. He bloated. It happened fast — the way it always does — and it required emergency surgery to save his life. GDV (Gastric Dilatation-Volvulus) is a condition where the stomach fills with gas and twists on itself, and it is as terrifying as it sounds. Without immediate intervention, it's fatal.
After Hemi, slow feeder bowls became non-negotiable in my house. For every dog. Forever.
Bullmastiffs are at elevated risk for bloat due to their deep chest and large size. Fast eating is one of the top contributing risk factors, and it's one of the few things you can actually control. I'm not being dramatic when I say that switching to a slow feeder bowl is one of the most important things you can do for a large breed dog.
A slow feeder bowl is not optional for this breed. It's a health decision.
What works: A maze-style slow feeder with a non-slip base large enough to hold a full meal (Bullmastiffs eat 4–6 cups per day depending on size and activity).
What to look for:
- 4-cup minimum capacity
- Non-slip base — they will push it across the room otherwise
- Dishwasher safe (because giant breed meal cleanup is already enough)
- Avoid very deep maze channels for flat-faced dogs — Bullmastiffs have a moderate muzzle, so medium-depth mazes work fine
On Amazon: The Outward Hound Fun Feeder Slo-Bowl (large size) is a consistently top-rated option that's BPA-free, dishwasher safe, and holds up to 4 cups. It extends mealtime significantly and is widely recommended by large breed owners.
For water, the Slopper Stopper is the only bowl I use. If you've never heard of it — it has a specialized lid design that prevents your dog's muzzle from getting soaking wet while drinking, which means no more water trails across your floor, no more soaked beard, no more slip hazards. Bullmastiffs are enthusiastic and messy drinkers, and a standard open water bowl in this house lasts about 30 seconds before the floor is soaked. The Slopper Stopper cuts that mess dramatically.
Important sizing note: it comes in multiple breed-size models based on weight and tongue length — for a Bullmastiff you'll want the Giant Breed sizing. There's a short break-in period of a week or two while your dog figures out the drinking technique, but once they get it they genuinely prefer it.
On Amazon: Search Slopper Stopper Dripless Water Bowl and select the Giant Breed model. It's also a small business brand, which is a nice bonus.
3. Joint Supplements: Start Earlier Than You Think
Having spent years working in the veterinary field, I've seen a lot of products come and go. Most supplements are fine. Some are great. A few are the real deal.
Dasuquin is the real deal.
I've watched it make a genuine difference in dogs' mobility and quality of life, and it's what I personally use for my own Bullmastiffs. I truly believe it's been a key part of why my dogs have aged as gracefully as they have. That's not a sponsored opinion — it's just what I've seen with my own eyes over years of working alongside veterinarians and caring for large breeds.
Bullmastiffs are a giant breed, and giant breeds age in their joints. Hip dysplasia is common in the breed, and the sheer weight they carry puts constant stress on their connective tissue. Most vets recommend starting joint support before problems appear — preventive, not reactive. Don't wait until your dog is limping to start thinking about this.
What to look for in a joint supplement:
- Glucosamine + Chondroitin — the core duo; supports cartilage and joint fluid
- MSM — helps reduce inflammation
- ASU (Avocado Soybean Unsaponifiables) — found in Dasuquin specifically; adds an extra layer of cartilage protection with clinical backing
- Omega-3s (fish oil or green-lipped mussel) — additional anti-inflammatory support
- Soft chew format — much easier than wrestling a pill into a stubborn Mastiff
On Amazon: Nutramax Dasuquin for Large Dogs is my top recommendation — it goes beyond the standard glucosamine/chondroitin formula with the addition of ASU, which has real research behind it. If you're looking for an entry point, Nutramax Cosequin is the same trusted brand at a more accessible price point. Both are widely recommended by veterinary professionals for a reason.
Always consult your vet before starting supplements, especially if your dog is on any medications — but don't be surprised if they're already recommending one of these.
The Bonus Essential: What I Take on Every Walk
Okay, this one's a shameless plug, but it's genuinely useful so I'm including it.
Walking three Bullmastiffs means I'm basically running a mobile command center. I need my hands free, my treats accessible, and my phone reachable — all while managing three leashes.
The Carhartt Crossbody Bag from The Craft Pack has become my ride-or-die for walks, hikes, and training sessions. It's rugged, adjustable, and fits everything: treat pouch, poop bags, phone, keys, and a collapsible water bowl. If you walk big dogs regularly, a crossbody beats a fanny pack every single time.
We customize them too — if you want your dog's name or breed on yours, we do that. Just saying.
The Bottom Line
Owning a Bullmastiff is one of the best decisions I've ever made — three times over. But this breed deserves gear that matches their size, their strength, and their health needs. The right collar, a slow feeder, and joint support from an early age will make a real difference in their quality of life.
Have a product that's been a game-changer for your Mastiff? Drop it in the comments — I'm always looking for what's actually working out there in the giant breed community.
