7 Best Companion Giant Dog Breeds
1. Bernese Mountain Dog
The Bernese Mountain Dog is the lovable goofball of giant dog breeds, with a heart as big as its paws. These gentle giants start off as fluffy, floppy-eared giant puppies and grow into majestic companions with tri-colored coats that turn heads everywhere.
Purina reveals that Berners are famous for their calm, affectionate nature and knack for bonding with the whole family—including kids and other pets. While some large dog breeds prefer alone time, Berners are total Velcro dogs; they live for love and cuddles.
With moderate exercise needs, a daily walk and a bit of play keep them happy. But don’t be fooled by their laid-back vibe—they do appreciate mental stimulation like puzzle games and training.
Grooming? Oh yes. That beautiful double coat means regular brushing, especially during seasonal shedding. You’ll find fur in places you didn’t know existed—but it’s worth every tumbleweed.
They’re one of the more trainable giant breed dogs, thanks to their eagerness to please and good-natured temperament. Just be patient and use positive reinforcement.
Their diet should support joint health and prevent rapid weight gain—think lean proteins and high-quality kibble formulated for large breeds.
Fun fact: Berners are often called the “gentle giants of the Swiss Alps,” and once you meet one, you’ll get why they’re one of the most lovable breeds out there.
2. Great Pyrenees
The Great Pyrenees is basically a living cloud with paws—and it’s just as soft on the inside. Originally bred to guard livestock, this majestic giant breed dog brings a calm, protective presence into any home.
They’re surprisingly gentle for such a large dog, making them a preferred breed for families and even as therapy dogs. Their loyalty runs deep, and they’re famously patient with children—like a furry, oversized babysitter.
These famous giant breeds do have an independent streak, so training giant dogs like the Pyr requires consistency and a calm but firm hand. They’re intelligent but selective listeners—kind of like fluffy philosophers.
Exercise needs are moderate, but mental stimulation is essential. Think quiet walks, scent games, and time to roam (fenced, of course—they’re natural wanderers).
That glorious white double coat? It requires weekly brushing and frequent touch-ups during shedding season. Also: drool is part of the deal—own it.
Feed them a balanced diet designed for large breeds to support joint health and avoid weight-related issues. They do best with scheduled meals and portion control.
Trivia time: These gentle giants were once considered royal guard dogs of France—talk about noble roots in your giant companions.
3. Leonberger
Leonbergers are the friendliest titans you’ll ever meet. Bred to resemble lions (yes, really), these kind giants mix strength with sensitivity, making them standout family dogs in the world of giant breeds.
From goofy puppyhood to regal adulthood, Leos are energetic, emotionally intelligent, and incredibly affectionate. They bond fiercely with their humans and have a special sixth sense for sensing emotions.
AKC notices that Leonbergers are highly trainable, but early socialization is a must. They’re people pleasers, but like many large breeds, they need structure, patience, and fun during training sessions.
Grooming is not optional. Their thick, water-resistant coats need brushing multiple times a week—especially those feathery tails and manes. Expect glorious golden fur on every surface.
Leos are playful but not hyper. A mix of moderate exercise and brain games keeps them balanced and happy.
Nutrition-wise, giant breed-specific formulas are essential, especially during their fast-growth puppy phase. Think joint-friendly, high-protein meals with balanced fat.
Fun fact: Leonbergers were once kept by European royals and even pulled carts. Today, they’re pulling hearts—one cuddle at a time.
4. Saint Bernard
The Saint Bernard is everyone’s favorite snow rescue icon—but at home, they’re better known for rescuing your heart. These giant companions are sweet, calm, and impossibly lovable.
They start off as wrinkly, clumsy puppies and grow into 180lb dogs who genuinely believe they’re still lap-sized. Despite their bulk, they’re gentle and make some of the best dogs for families.
Training Saint Bernards is surprisingly easy—they’re eager to please but can be a bit stubborn. Keep it light, consistent, and full of praise (and snacks).
Saints are big fans of leisure. A couple of good walks and some playtime keep them happy. Just don’t expect marathon runs—these dogs are more about vibes than velocity.
Their short-to-medium coats shed seasonally and need weekly brushing. Oh, and yes—they drool. A lot. Keep towels handy and embrace the slobbery charm.
Feeding? Large breed-specific diets that focus on bone and joint support are key, especially during their rapid growth years.
Did you know? They were bred to rescue lost travelers in the Alps, but today, they’re mostly in the business of emotional rescue—and they’re pros.
5. Great Dane
Meet the gentle skyscraper of the dog world. The Great Dane is one of the tallest breeds on Earth, but don’t let the height fool you—they’re softies at heart and among the best large dog companions.
Britannica claims that Great Danes are calm, affectionate, and famously loyal. They love leaning into their humans (literally), earning them the nickname “leaning dogs.” Yes, they’re large, but they’ve got the emotional intelligence of a seasoned therapist.
Despite their intimidating size, they’re a docile breed and surprisingly easy to train. Early socialization and positive reinforcement go a long way with these smart, sensitive souls.
Exercise needs are modest—short walks and play sessions do the trick. Just avoid strenuous activity while they’re still growing, as their joints are delicate.
Their sleek coats are low-maintenance, shedding moderately with weekly brushing. Plus, there’s a rainbow of colors to enjoy—from fawn to harlequin.
Feeding requires care. Stick to large breed formulas and monitor portion sizes to prevent bloat—a common concern with this giant dog.
Fun fact: Scooby-Doo was a Great Dane, proving they’re not just one of the tallest breeds but also cartoon icons with big-bark energy.
6. Alaskan Malamute
Alaskan Malamutes are the bodybuilders of the giant breed world—muscular, majestic, and always ready for a snowy adventure. But underneath that powerful build? A total softie who thrives on companionship.
They’re incredibly loyal, forming strong bonds with their humans, and love being part of a pack. That makes them great family dogs, though they do better with older kids due to their size and strength.
Training giant dogs like the Malamute takes patience—they’re smart but independent. Start young, keep sessions fun, and brace yourself for a bit of stubborn flair.
They’re high-energy and need daily exercise—lots of it. Think hikes, pulling weights (yes, really), and mentally stimulating games. Couch potato life? Not their style.
That gorgeous double coat needs serious maintenance. Weekly brushing is a must—and during shedding seasons, break out the heavy-duty vacuum.
Feed them a nutrient-rich diet suited for athletic dogs. They burn energy like champs, so quality calories count.
Fun trivia: Malamutes once hauled freight across the Arctic, but today, they’re hauling hearts into snow-filled, tail-wagging bliss.
7. Dogue de Bordeaux
The Dogue de Bordeaux is the stoic, wrinkly-faced giant with a heart of gold—and a snore that could shake the windows. This kind giant breed is famously loyal, calm, and quietly affectionate.
From puppyhood, they develop into powerful yet emotionally tuned-in companions. They form intense bonds and thrive on one-on-one attention, making them ideal for calm households or devoted individuals.
Though not the most eager students in obedience class, they’re incredibly trainable with firm, consistent, and gentle guidance. No harshness—these sensitive souls respond best to kindness.
They’re low to moderate in activity needs. Daily walks and some light play are enough to keep them content. They also appreciate quiet downtime (they are champion nappers).
Grooming is easy thanks to their short coats, but their adorable wrinkles need cleaning to prevent irritation. Expect drool—and lots of it. Embrace the slobber life.
PDSA suggests that their diet should be tailored for large breeds to support healthy bones and joints. Portion control is vital—they can pack on pounds quickly.
Fun fact: The Dogue starred alongside Tom Hanks in Turner & Hooch. Yes, that slobbery, scene-stealing star was one of these lovable giants!
