When you think of giant dog breeds, you might imagine towering, powerful figures with booming barks and intimidating frames. But beneath all that size lies something many people don’t expect—an incredibly loving, gentle, and affectionate heart.
Gentle giant dog breeds are often known as “gentle giants” for a reason: they adore their families, form deep bonds, and bring a calming, comforting presence wherever they go. These breeds may be massive in stature, but they’re famously soft in spirit.
Many of these giant breeds are patient with children, loyal to their families, and naturally calm in everyday life. Their size may command attention, but it’s their emotional warmth and devotion that make them truly unforgettable companions.
We’ll celebrate giant dog breeds that pair impressive physical presence with loving personalities. These dogs thrive in homes where they can be close to their people, offering both companionship and a sense of security.
Did you know? Despite their massive size, many large dog breeds are known for having lower stress responses and gentler temperaments than smaller breeds.
Fantastic Giant Dog Breeds & Their Loving Nature
1. Great Dane

The first gentle giant on our list is none other than the German Mastiff—better known as the Great Dane. If dogs had a professional basketball league, Great Danes would be the star players.
Weighing up to 200 pounds, these tallest dog breeds certainly know how to make an entrance. Just don’t be surprised if their idea of “sitting in your lap” feels more like being crushed by a furry boulder of affection.

Despite their impressive size, Great Danes are the embodiment of calm, kind-hearted companionship. These big dogs may look like they could guard the gates of a medieval castle, but most of them are just big, goofy cuddle machines who want nothing more than to be part of the family.

Enormous size… but even bigger hearts
Friendly, gentle, and excellent with families
Surprisingly calm for their size
PetMD notes that their size can be intimidating at first, especially when they come trotting toward you like a small horse, but their warm, mellow nature quickly melts away any fear. And here’s something many people don’t realize: Great Danes are incredibly sensitive souls.
Yes, behind that colossal frame is a dog who notices your mood faster than your best friend does. They’re the type to nudge your hand gently when you’re sad or quietly rest their massive head on your chest to offer comfort.
This sensitivity forms the foundation of their deep, meaningful bond with their humans. Great Danes truly want to be part of your world—your snuggle sessions, your backyard adventures, even your attempts at working on the couch.
No matter what, they bring an unforgettable blend of love, gentleness, and comedic clumsiness into your life. With a Great Dane, every day is a little brighter… and a little more crowded on the furniture.
2. Saint Bernard

If Great Danes are the gentle giants of the dog world, Saint Bernards are the warm-hearted mountain monks.
These massive fluffballs are famously known for their heroic roles in search and rescue missions—bounding through snowdrifts with the determination of a dog on a mission and the gentleness of a living teddy bear.
Saint Bernards don’t just save lives; they redefine what it means to be a dependable companion. Their natural intuition and compassion make them excellent therapy dogs.

Need emotional support? A Saint Bernard will happily plop its enormous, droopy face onto your lap (whether you’re ready or not). Need cheering up? Their soulful eyes and goofy grins do the trick every time.

Naturally gentle disposition, patient nature, and compassionate
Fantastic therapy dogs
Strong search-and-rescue instincts
When properly trained and socialized from a young age, Saint Bernards become wonderfully loyal family companions. They adore children, get along well with other pets, and are always eager to be part of the household action—preferably the part involving snacks.
With a Saint Bernard in the house, you don’t just get a dog—you get an excellent companion, an emotional support system, and a gentle mountain guardian all rolled into one fuzzy, lovable package.
3. Newfoundland

If giant dog breeds had a “Best Babysitter” award, the Newfoundland would win it every year without even trying.
Affectionately known as Newfies, these gentle giants have a calm, patient presence that makes them feel like the wise, dependable friend everyone wishes they had—only fluffier and much more drooly.
Known for their sweet temperament and impressive tolerance, Newfoundlands are especially adored for how well they get along with children. Many families lovingly refer to them as the “nanny dog,” and for good reason.

According to the AKC, the Newfie has earned a reputation for being a patient, watchful, and comforting companion for kids—basically Mary Poppins in dog form, minus the umbrella (though they’d probably try to carry it for you).
Why people adore Newfies
Exceptionally patient with children
Calm, affectionate, and gentle-natured
Natural therapy dogs who offer warmth and comfort
Their soft-hearted temperament makes them wonderful therapy dogs. Whether it’s providing reassurance during emotional moments or just being a massive, comforting presence to lean on, Newfoundlands seem to have an instinct for nurturing.
Despite their impressive size, Newfoundlands aren’t overly demanding. They enjoy steady, moderate activity—think peaceful walks and short play sessions rather than action-packed hikes.
And once they’re home? Prepare for a whole lot of cuddly coziness. Just be warned: when a Newfie decides to nap on your feet, you’re not moving anytime soon.
4. Mastiff

The Mastiff is the original “gentle giant with a knight’s résumé.” With a history stretching back more than 2,000 years in England, these colossal canines once stood guard over estates and even stepped into battle when duty called.
Today, they’re far less interested in fighting and far more interested in claiming every soft surface in your home as their personal throne. One thing you should know right away: the Mastiff’s size isn’t just “big.” It’s “need-an-extra-couch” big.

Despite their intimidating appearance, Mastiffs have heartwarming personalities.
They’re affectionate, extremely loyal, and—much to the amusement of every Mastiff owner—often try to be lapdogs. Nothing says “love” like a 170-pound dog attempting to curl up on your knees while you pretend to breathe normally.
Affectionate guardian and eager to please
Friendly with the family, aloof with strangers
Surprisingly compatible with other pets
These guard dogs require plenty of exercise regularly and room to stretch out, preferably on soft, cushy bedding—because if you think you enjoy comfort, wait until you see a Mastiff settle down for a nap. You’ll question every mattress you’ve ever owned.
While they make great companions for people of all ages, their sheer mass and strength can be a challenge for young children or seniors to handle, so proper socialization is a must!
As noted by Britannica, Mastiffs make excellent watchdogs thanks to their deep, resonant bark and naturally protective instincts. They’re not “alarm systems” that bark at every leaf—these dogs speak only when something truly warrants attention.
Unfortunately, Mastiffs are not one of the longest-lived dog breeds, typically having a life expectancy of 6 and 10 years. They are also prone to certain health issues, including gastric dilatation-volvulus (GSV), a dangerous condition, and stomach bloating and twisting.
Owners must be vigilant and prepared for emergency veterinary care if needed.
5. Bernese Mountain Dog

Straight from the snowy slopes of Switzerland comes one of the gentlest giants of all time: the Bernese Mountain Dog.
Though they can weigh upwards of 120 pounds, these dogs are far from intimidating. In fact, they’re basically living marshmallows—massive frame, fluffy, sweet, and surprisingly soft around the edges.
If you need a dog that doubles as a cuddle partner and a living space heater, the Berner has you covered. These big furballs are famously gentle and make excellent family pets.

Their warm, affectionate nature pairs beautifully with their striking tricolour coat—so don’t be surprised if your visitors start swooning over them before they even step inside the house.
Gentle, social, and fantastic with families
Friendly nature paired with working-dog spirit
Gorgeous double coat (and plenty of shedding to go with it!)
Bernese Mountain Dogs thrive in cooler climates thanks to their thick double coat, which acts like a built-in winter jacket. These cold-ready coats provide insulation and protection against harsh weather.
But don’t worry—they’re surprisingly adaptable and can adjust well to different climates, making them a versatile choice for many households
Beyond their charm and beauty, Berners are also excellent therapy dogs. Their calm presence, soft expression, and intuitive nature make them natural comfort-givers.
Whether they’re visiting care facilities or simply being emotional support for their own families, Berners bring an unmistakable warmth everywhere they go.
Strength, sweetness, and a dash of Swiss charm—Bernese Mountain Dogs check all the boxes. For families who want a loving, loyal giant with a flair for outdoor fun, the Berner is a truly beautiful pick.
6. Leonberger

If a lion and a teddy bear teamed up to create the world’s most majestic couch potato, you’d get the Leonberger.
With their fluffy manes, soulful eyes, and impressive size, Leonbergers can look like royalty patrolling the living room—but in reality, they act more like laid-back babysitters who just want everyone to get along and enjoy a snack.

Despite their regal appearance, Leonbergers are famously gentle, calm, and deeply family-oriented. They adore human company and are particularly known for their patience with children. Think of these large dogs as oversized peacekeepers who defuse household chaos with a single wag of their tail.
Calm, gentle, and wonderfully good-natured
Great with kids and other pets
Adore family time and staying close to their humans
One of their unique joys? Water. Leonbergers love it. Many take to swimming naturally, paddling through lakes and pools with the grace of professional doggy lifeguards. If you’ve ever dreamed of a giant furry friend who happily joins you by the water, this breed is your aquatic friend.
Early socialization is important, just like with any large breed. Fortunately, Leonbergers are quick learners with big hearts—they just need guidance to grow into the confident, sociable giants they’re meant to be.
With all that glorious fur, regular grooming is a must. According to the PDSA, Leonbergers should be brushed a couple of times a week to remove dead hair and keep their coat looking its royal best. Consider it bonding time… and maybe a mild workout.
7. Great Pyrenees

If clouds had legs, they’d probably look like the Great Pyrenees dog. Majestic, fluffy, and impossibly calm, these dogs were originally bred to guard livestock in the Pyrenees Mountains—meaning they’re basically nature’s gentle guardians wrapped in a snowy, thick coat.
Don’t let their serene vibe fool you, though. Beneath all that fluff lies a heart of courage and a watchdog instinct sharper than you’d expect from a dog who naps like it’s a full-time job.

Great Pyrenees are famously gentle and affectionate with their families. They form deep bonds with their humans and often stay close, quietly watching over everyone like the world’s most loving (and largest) security blanket.
Calm, patient, and incredibly loyal
Natural protectors with a loving streak
Gentle giants that adore family life
Their background as livestock guardians means they were literally born to protect. They’re alert, watchful, and equipped with a booming bark that can send any intruder reevaluating their life choices. Fortunately, they’re not aggressive—just confidently protective and deeply committed to keeping their territory safe.
Of course, that magnificent coat does come with responsibilities. The Great Pyrenees sheds… a lot. You will find fur in places you didn’t know existed. But with regular brushing, they stay clean and glorious—plus, it’s the perfect chance for some bonding time with your fluffy mountain dog.
Conclusion
Fantastic giant dog breeds and their loving nature are adored not just for their size but for their gentle personalities.
Whether it’s the Irish Wolfhound with its long legs and history of hunting wolves, the English Mastiff or French Mastiff with their big personalities and protective nature, or the Neapolitan Mastiff, well-suited for guarding sheep and comforting stranded travellers, these big dogs consistently show deep devotion to their loved ones.
With proper training, obedience training, and enough exercise—from a long walk to daily exercise—these even-tempered, even big companions thrive alongside family members, other dogs, and other animals.
Known for reading human emotions and enjoying human interaction, these big dog breeds make great pets, loyal rescue dogs, and affectionate guardians who offer more food, more love, and endless loyalty in return.
