Big dogs get all the attention. Great Danes, Mastiffs, Saint Bernards… you know the names.
But there’s a whole world of giant dog breeds that most people have never even heard of. Some of them are even more impressive than the famous ones.
These are the dogs that don’t show up on every “large dog breeds” list you scroll past. The dogs that make people stop mid-walk and go, “WAIT a minute… what IS that?”
If you have the space, time, and heart for a large-stature canine companion that’s a little off the beaten path, this list of the big dog breeds is what you need.
Let’s get into it.
Fun Fact!
The Tibetan Mastiff holds the record for one of the most expensive dogs ever sold; a red Tibetan Mastiff reportedly sold in China for nearly 2 million dollars back in 2014. Giant guardian breeds like this one were status symbols among wealthy buyers in parts of China. Wild what people will pay for a dog with that much presence, right?
Magnificent, Uncommon Giant Dog Breeds to Consider
1. Leonberger
Thick golden fur, a lion-like mane, and an impressive build.
That is the Leonberger.
These large dogs were originally bred in the German town of Leonberg to resemble the lion on the town’s coat of arms (yes, seriously). This breed was bred to be both a working dog and a companion.
Leonbergers have a thick double coat that needs regular grooming to stay healthy and manageable. Daily brushing keeps shedding under control, according to the American Kennel Club. During seasonal blowouts, you will want to step it up.
Despite their large stature, these gentle giants are famous for being incredibly affectionate with kids, other pets, and pretty much anyone who walks through the door.
They are calm indoors, playful outdoors, and make great companions for families with the space to accommodate a dog this size.
Height-wise, males can reach up to 31 inches at the shoulder. So, yeah, this is a big dog breed in every sense.
2. Dogue de Bordeaux
Scruffy-faced, wrinkly, and dripping with personality, the Dogue de Bordeaux is one of France’s oldest large dog breeds, and honestly, one of the most underrated.
Historically used as a guard dog and for pulling heavy carts, this breed carries a brawny, muscular build that makes it look way tougher than it behaves at home.
Most owners will tell you their Dogue de Bordeaux is basically a giant softie with intense loyalty toward their family.
These MASSIVE dogs are characterized by their wrinkled faces, deep-set eyes, and stocky, powerful frames, according to Omlet UK. They can weigh well over 100 pounds. Despite that energy, these brown dogs are affectionate, gentle with children, and content to be near their people most of the day.
Grooming needs are pretty minimal thanks to their short coat, though those facial wrinkles do need regular wiping to avoid skin irritation.
A rare breed that deserves way more attention.
3. Black Russian Terrier
Dark, tense, and a little intimidating at first glance, the Black Russian Terrier was bred by the Soviet military to serve as a working dog for guarding and patrol duties.
That history shows.
These black dogs are confident, alert, and naturally protective, but they are also deeply affectionate with their own family once trust is established.
Their thick, wiry coat requires consistent grooming, regular brushing, and occasional trimming to keep it from matting into an unmanageable mess.
Unlike a lot of other breeds on this list, Black Russian Terriers don’t shed heavily, which is a nice BONUS for a dog this size.
Height typically runs between 26 and 30 inches, according to PetMD. That puts them solidly among the biggest breeds, beloved for their size.
Great companions for experienced owners who want a large, military dog paired with serious loyalty.
4. Scottish Deerhound
If most large dog breeds look like brawny linebackers, the Scottish Deerhound looks like it was in a Renaissance painting. Tall, lean, and elegant, this ancient breed was originally used to hunt red deer across the Scottish Highlands.
Don’t let the graceful, Greyhound-like build of these brawny dogs fool you.
Scottish Deerhounds are genuinely large dogs, with males usually standing over 30 inches tall. Their coat is shaggy and wiry. They need moderate grooming compared to most dog breeds.
These dignified dogs are calm, quiet, and deeply affectionate with their family. But these hound dogs are a little reserved around unfamiliar dogs and strangers at first.
Given their sighthound background, they do need to run and burn off energy; small apartments are not exactly ideal here.
5. Tibetan Mastiff
Tibetan Mastiffs are huge, independent, and fiercely protective of their home and family. Their thick, lion-like mane and dense double coat make them look almost mythical, and in person, these muscular dogs are every bit as impressive as photos suggest.
These dogs need significant grooming due to that heavy coat. Brushing several times a week helps manage shedding during coat-blowing season.
They are not typically great with unfamiliar dogs or strangers. Their guarding instincts run deep, so early socialization is important.
For experienced owners with space and time to dedicate to training, Tibetan Mastiffs make loyal, watchful companions unlike almost any other breed.
6. Greater Swiss Mountain Dog
Sturdy, tricolored, and built like an absolutely powerful dog, the Greater Swiss Mountain Dog was historically used to pull carts and drive livestock across the Swiss Alps.
These are working dogs, but don’t mistake that history for a lack of affection.
These mountain dogs are famous for being incredibly gentle with children and great companions for active families with enough space to house a dog this large.
Their coat is short to medium in length. That makes grooming relatively manageable compared to other big dogs on this list. Weekly brushing usually does the trick.
Height-wise, they typically reach around 28 inches. Weight can easily climb past 140+ pounds for males.
Calm, steady, and manageable, these tricolored dogs bring presence without the intensity some other giant dogs carry.
7. Romanian Mioritic Shepherd Dog
Rounding out this list is a breed most people in the United States have never heard of: the Romanian Mioritic Shepherd Dog.
Bred for centuries in the Carpathian Mountains to guard livestock against wolves and bears, this livestock guard breed carries a thick, shaggy coat that protects against harsh mountain weather. Their appearance is almost bear-like, all that fur with a large, sturdy frame.Â
Romanian Mioritic Shepherd Dogs are calm, watchful, and deeply loyal to their flock, human or animal. They are wary of unfamiliar dogs and people at first, a natural trait from generations of guarding work.
But they warm up once they know you are part of their circle.
Grooming this thick coat takes real commitment. Regular brushing multiple times a week keeps mats at bay.
A rare dog breed in the West, but appreciated one among people looking for a unique, friendly dog.
Conclusion
Big dogs don’t mean the same handful of breeds everyone already knows. These uncommon giant breeds prove that there is a whole world of biggest canines most people never even get the chance to meet.
Sure, they come with real commitments, more grooming, more space, more food, more everything, honestly. But in return, you get dignified pooches with big hearts to match their huge size.
If you have the room and the love to give, one of these gentle giants may become the most impressive, gorgeous addition your home has ever seen.
