If you’ve ever seen a dog that looks like a Labrador but has the "soulful eyes" and massive frame of a mountain dog, you’ve probably met a Labernese. It's a mouthful. The black lab bernese mountain dog mix is basically what happens when you take the world’s most popular family dog and cross it with a Swiss giant that thinks it’s a lapdog.
People are obsessed with Doodles right now. Honestly? I think they’re missing out. While everyone else is fighting over hypoallergenic fur and poodle curls, the Labernese is quietly winning the "best roommate" award. They are big. They are goofy. They will absolutely shed all over your favorite rug. But if you want a dog that will watch a three-hour movie with you without moving an inch, this is the one.
What is a Black Lab Bernese Mountain Dog Mix, Really?
We’re talking about a first-generation (F1) crossbreed. You take a purebred Labrador Retriever—usually a black one to get that sleek, midnight coat—and a purebred Bernese Mountain Dog.
The result isn't always predictable. Genetics are weird like that. Some pups come out looking exactly like a Lab but with a "blockier" head and a thicker chest. Others get the Berner’s longer, wavy coat and those distinct tan points, though a true "black lab" mix often results in a solid black dog or a black dog with a white "star" or "medallion" on the chest.
Size-wise? Prepare your furniture. A male can easily hit 80 to 110 pounds. Females are a bit smaller, usually staying between 65 and 85 pounds. If you live in a tiny studio apartment on the fourth floor with no elevator, stop reading now. This dog needs space. Not necessarily for running marathons—they’re actually kind of lazy—but just for existing. They take up a lot of floor real estate.
The Temperament Flip-Flop
Here is the thing about the black lab bernese mountain dog mix: they have a bit of a split personality.
- The Lab side wants to fetch. It wants to swim. It wants to eat your drywall if it gets bored.
- The Bernese side wants to nap. It wants to lean against your legs until you fall over. It is naturally cautious.
When you mix them, you usually get a dog that is less "intense" than a pure Lab but more outgoing than a pure Berner. Bernese Mountain Dogs can be notoriously shy or "aloof" with strangers. Labs, conversely, think every stranger is a long-lost best friend. The mix tends to hit a sweet spot. They’ll bark when someone knocks on the door, but once the guest is inside, the dog is basically a giant, furry welcome mat.
The "Velcro Dog" Reality
If you value your personal space, don't get this dog. Seriously. The Bernese influence creates what breeders and owners call a "Velcro dog." They don't just want to be in the same room as you; they want to be on you.
I’ve seen 100-pound Labernese try to climb into the laps of people sitting in recliners. It’s hilarious until it’s your lap. They have this specific "Berner Lean" where they press their entire body weight against your shins. It’s a sign of affection, but it’s also a tripping hazard.

Health and Longevity: The Elephant in the Room
We have to talk about the "Heartbreak Breed" reputation. Bernese Mountain Dogs, unfortunately, have one of the shortest lifespans in the canine world, often only 7 to 9 years. They are prone to a nasty cancer called Histiocytic Sarcoma.
The good news? Crossing them with a Labrador—which usually lives 10 to 12 years—can introduce "hybrid vigor." This isn't a magic shield against disease, but it generally broadens the gene pool. You’re looking at a life expectancy of roughly 9 to 12 years.
You still have to watch out for:
- Hip and Elbow Dysplasia: Both parent breeds are heavy. Their joints take a beating.
- Bloat (GDV): This is a medical emergency. Because they have deep chests, their stomachs can flip. You’ve gotta use slow feeders and avoid heavy exercise right after meals.
- Ear Infections: Those floppy ears are cute, but they trap moisture. If your dog spends the afternoon in a pond, dry those ears out or you’ll be paying the vet a lot of money for drops.
The Shedding Situation (It’s a lot)
You will find hair in your butter. You will find hair in your freezer. You will find hair in places where the dog hasn't even been.
A black lab bernese mountain dog mix has a double coat. The Lab part gives them a dense, water-resistant undercoat. The Berner part adds length. Twice a year, they will "blow" their coat. It looks like a snowstorm of black fur.
Invest in a high-quality slicker brush and a vacuum that doesn't give up on life after five minutes. If you’re the type of person who wears all-white linen outfits, this is not the dog for you. You are now a person who wears black and carries a lint roller in every bag.
Training: Intelligence vs. Stubbornness
Labs are famously easy to train because they are motivated by one thing: food. They would do a backflip for a piece of kibble.
Bernese Mountain Dogs are smart, but they can be sensitive. If you yell at a Berner, they might pout for three days. They have a "soft" personality.

When training your mix, keep it positive. Use high-value treats (think freeze-dried liver or plain boiled chicken). They learn quickly, but they might decide to do things on "Bernese time," which is a slightly slower pace than the frantic "Yes, sir!" attitude of a Lab.
Socialization is the most important thing. Because the Bernese side can be wary, you need to introduce your puppy to everything. Potholes, umbrellas, bearded men, bicycles, cats. Do it early. An unsocialized 100-pound dog is a liability. A socialized 100-pound dog is a community treasure.
Exercise Needs: Don't Overdo It
A lot of people think "Big Dog = Big Exercise." Not really.
A black lab bernese mountain dog mix needs a good 45 to 60 minutes of movement a day, but they aren't marathon runners. They are hikers. They love a long, sniffing walk through the woods. They love a slow swim in a cold lake.
In fact, you have to be careful in the summer. That black, double coat is like wearing a parka in a sauna. On days over 80 degrees, keep the walks short and stick to the shade. If they start panting excessively and their tongue looks extra wide and flat, get them into the AC immediately.
Finding a Labernese: The Ethics
You probably won't find a "Labernese" at a fancy kennel club show. This is a designer mix. That means you have to be extra careful about where you get one.
Avoid pet stores. Avoid anyone on Craigslist who can't show you health clearances for the parents. A reputable breeder should be testing the parents for hip scores (OFA or PennHip) and heart issues.
Better yet? Check Lab rescues and Bernese rescues. Because these dogs are big and shed a lot, people sometimes surrender them when they realize they can't handle the "big dog lifestyle." You might find a perfect two-year-old who is already house-trained and past the "chewing everything I own" phase.

The Reality of the "Black Lab" Look
Interestingly, even if one parent is a tri-color Bernese (Black, White, and Rust), the black gene in Labs is very dominant. Most of these mixes end up being solid black.
Why does this matter? Black Dog Syndrome. It’s a sad fact in shelters that black dogs are adopted less frequently than lighter-colored dogs because they are harder to photograph and can look "scary" in dim light. If you’re looking for a black lab bernese mountain dog mix, you’re getting a dog that looks like a majestic shadow. They are stunning in person, even if they don't always show up well in your iPhone photos.
Cost of Ownership
Expect to pay more for everything.
- Food: They eat 3 to 5 cups of high-quality large-breed kibble a day.
- Vetting: Heartworm and flea preventatives are priced by weight. A 100-pound dog costs double what a 20-pound dog costs.
- Boarding: Many facilities charge extra for "giant" breeds.
- Grooming: Unless you want to do the "bath and blowout" yourself—which takes hours—professional grooming will run you $100+ every few months.
Is This the Right Dog for You?
Honestly, the black lab bernese mountain dog mix is one of the most balanced dogs out there if you have the space. They aren't as high-strung as a Border Collie, and they aren't as lazy as a Saint Bernard. They sit right in the middle.
They are world-class cuddlers. They are gentle with children (though they might accidentally knock a toddler over with a wagging tail). They are loyal to a fault.
If you can handle the fur, the potential health heartbreak, and the fact that you will never go to the bathroom alone again, you’ll find that this mix is probably the most affectionate companion you’ll ever own.
Practical Next Steps for Potential Owners
- Audit your vehicle: Can your car fit a 100-pound dog comfortably? If you drive a Miata, you’re going to have a problem.
- Measure your space: Ensure you have enough room for a "giant" size dog crate. It’s roughly the size of a small dining table.
- Research local vets: Find one experienced with giant breeds and ask about their experience with GDV (Bloat) preventative surgeries like gastropexy.
- Check the fences: Labs are explorers. Make sure your yard is secure. A Labernese won't usually jump a fence, but they might lean on a weak one until it gives way.
- Budget for the "Big Dog Tax": Set aside an emergency fund specifically for joint supplements and potential large-scale vet bills as the dog ages.
Moving forward with a Labernese means committing to a "big life." It’s messy and hairy, but the first time that huge head rests on your knee after a long day, you'll realize the vacuuming is a small price to pay.
