Did you know? Some dog breeds are considered rare because of limited population, geographic isolation, or specialized breeding purposes.
Dog Breeds That Are Truly a Rarity to See
1. Boerboel
At first glance, the Boerboel might look like it walked straight out of a superhero comic—massive, muscular build, and ready to protect its home from anything that dares to approach. And yes, this breed does make an excellent guard dog.
But don’t let the tough exterior fool you: underneath that powerful frame is a heart of gold, especially when it comes to family. These gentle giants are calm, affectionate, and surprisingly tender with children.
Boerboels are relatively low-maintenance when it comes to grooming and tend to have fewer health problems than many large breeds. But don’t be fooled into thinking they’re a “lazy couch potato” breed.
They are confident, territorial, and yes… they will pull on the leash and chew your shoes if you let them. So, first-time dog owners beware: this breed isn’t for the faint of heart.
These dogs thrive in homes with plenty of space to roam—think big backyards with a strong, high fence. Give them room to move and the right guidance, and they’ll repay you tenfold with loyalty, affection, and a willingness to defend their family like furry bodyguards on four legs.
Fun Fact: Boerboels have been known to carry logs twice their size while playing in the backyard. Basically, they’re like your friendly neighborhood strongman—if your neighborhood needed a very large, very loving guard dog.
2. Black Russian Terrier
Don’t let the name fool you—this isn’t just a “mysterious black dog that looks cool in the shadows.” The Black Russian Terrier was bred with one mission in mind: work hard, look secondary, as noted by PetMD.
Early versions of the breed were more about strength, stamina, and versatility than about winning beauty contests.
Today, they still carry that working-dog attitude, combined with a striking, bear-like appearance. These dogs have a serious work ethic.
If you don’t give them a job—or at least plenty of mental and physical stimulation—they might invent one of their own… and that job could involve rearranging your furniture or “testing” your sneakers for durability.
As per Wikipedia, early, firm, and consistent training is essential, and these smart pups excel at obedience competitions. They also shine in agility courses, Schutzhund training, and basically any dog sport that lets them show off their brains and brawn.
Their thick, jet-black coat is low-shedding but high-maintenance—it loves a weekly grooming session or two. Think of it as the Black Russian Terrier’s version of a stylish suit that always needs ironing.
Fun Fact: Despite their intimidating appearance, many Black Russian Terriers are complete goofballs at home. They’ll happily flop onto the couch beside you and act like a 100-pound lapdog—just don’t tell them the math doesn’t add up!
3. Estrela Mountain Dog
Meet the Estrela Mountain Dog—or as the locals in Portugal might call them, Cão de Serra da Estrela—one of the oldest and most noble breeds from the Iberian Peninsula.
These dogs were born to brave the rugged mountains, guarding flocks and families alike, and they do it with a combination of courage, intelligence, and, occasionally, dramatic flair.
While they’re formidable protectors on the clock, Estrelas are total softies at home. They adore their families, especially kids, and thrive on close companionship. Think of them as mountain-sized teddy bears: impressive from afar, huggable up close.
Their unique coats are built for the elements, coming in long or short varieties that resemble goat hair and a palette of fawn, wolf gray, yellow, or brindle. Rugged yet beautiful, they were practically engineered for outdoor adventures—but don’t forget, these dogs still need a safe, secure yard to stretch their legs and explore.
Estrela Mountain Dogs aren’t exactly the breed for first-time dog owners. Their independent streak means they respond best to experienced hands who understand the balance between gentle guidance and letting a working dog work.
Fun Fact: Estrelas are such natural guardians that stories abound of them standing between their humans and wild animals—even wolves—without a second thought.
4. Leonberger
If you’ve ever wanted a dog that looks like a majestic lion but acts like a gentle giant, meet the Leonberger. Calm, quiet, and regal, these dogs exude a “king of the living room” vibe—but don’t confuse their tranquility with laziness.
Leonbergers are surprisingly active outdoors and need more than a casual stroll around the block; think hikes, playtime, and adventures that match their lion-sized energy.
These dogs are highly intelligent and eager to please, making them very trainable—though a touch of stubbornness may pop up now and then. They’re not aggressive with people, but as they mature, they can become a bit reserved around strangers.
In other words, they’ll politely judge your guests from a safe distance before deciding if they’re worthy of cuddles. Hillspet noted Leonbergers aren’t suited for life in a kennel—they crave closeness with their humans and thrive in homes where they’re part of the family pack.
Give them love, attention, and plenty of outdoor activity, and they’ll reward you with loyalty, affection, and a presence that’s impossible to ignore.
Fun Fact: Leonbergers were originally bred to resemble the lion on the city of Leonberg’s coat of arms. So, technically, owning one is like having a lion roommate… who drools on the carpet instead of hunting wildebeests.
5. Dogue de Bordeaux
Meet the Dogue de Bordeaux, also known as the French Mastiff—a dog that looks like it could win a “world’s grumpiest face” contest but will melt your heart the moment you scratch behind its massive jowls.
Don’t let that wrinkled, muscular exterior fool you: these dogs are loyal, affectionate, and downright devoted to their families. Dogue de Bordeauxs are incredibly strong and protective, making them natural guardians of the home.
But they also have a gentle nature, especially with children, earning the nickname “big softies in disguise.” They love spending time with their humans and don’t do well being left alone for long stretches—they crave companionship almost as much as they crave their next meal (and yes, they do enjoy food).
These dogs are intelligent but can be stubborn, so early training and consistent boundaries are key. They’re not the most energetic breed, but daily walks and some mental stimulation keep them happy and healthy.
Fun Fact: Despite their intimidating looks, many Dogue de Bordeauxs have a hilarious “puppy personality” that lasts well into adulthood. It’s not uncommon to see a 120-pound mastiff awkwardly trying to curl up on your lap… and failing spectacularly.
6. Borzoi
If elegance had a canine form, it would be the Borzoi. Also known as the Russian Wolfhound, this breed looks like it just stepped out of a royal portrait—long, smooth coat, graceful build, and the kind of aristocratic air that makes other dogs look like they forgot their manners.
Borzoi were bred as hunting dogs, originally chasing down wolves across the Russian steppes. They’re fast, agile, and independent thinkers, which means they can sometimes seem a little aloof… especially if they’re busy admiring their reflection in the pond.
Despite their dignified demeanor, Borzois are gentle and affectionate with their families, forming strong bonds with the humans they trust.
These dogs are not couch potatoes—they love a good run in a secure, open space—but they also enjoy lounging elegantly afterward, preferably somewhere they can survey their kingdom (or your living room) in style.
Fun Fact: Borzois can reach sprinting speeds of up to 35 miles per hour! That’s faster than most cars in a residential zone—so maybe don’t challenge one to a race unless you’re feeling brave… or slightly reckless.
7. Greater Swiss Mountain Dog
Meet the Greater Swiss Mountain Dog—often affectionately called the “Swissy”—a tri-colored, mountain-sized bundle of loyalty, strength, and charm.
With a striking black, white, and rust coat and a build that could give a small car a run for its money, these dogs were originally bred in the Swiss Alps as all-purpose farm workers.
They weren’t just herders—they pulled carts, guarded farms, and probably would have organized your pantry if they could figure out the doorknob.
Swissies are calm and confident, with a natural, gentle demeanor that makes them excellent family dogs. They thrive on being part of the pack and love companionship, which means they’re happiest when included in daily family life.
Don’t be surprised if your “walk around the block” ends with a few laps of you being politely dragged along—their outdoor energy is boundless, and they love a good hike or a romp in a secure yard.
Despite their imposing size, they’re friendly and approachable, though their wagging tails are basically wrecking balls for anything left in their path. With early socialization and guidance, a Swissy can be a perfect mix of guardian, athlete, and affectionate cuddle companion.
Fun Fact: Greater Swiss Mountain Dogs are so strong that they were once used to pull carts loaded with milk and supplies across rugged mountain terrain.
Conclusion
Many of the rare dog breeds were bred for hunting small and large game, otter hunting, hunting puffins, or to guard livestock, with some sporting webbed feet, six toes, or a dense coat for specialized work. These intelligent dogs require regular exercise, mental exercise, and positive reinforcement to thrive.
Over a decade or more, these loyal dogs become great companions, combining rare appearances, playful personalities, and working breed instincts, recognized by the American Kennel Club and celebrated among lesser-known breeds in the world.
Rare dog breeds like the Canaan Dog, Bedlington Terrier, Cesky Terrier, Catahoula Leopard Dog, Ibizan Hound, Skye Terriers, Mudi Dogs, Grand Basset Griffon Vendéen, Dandie Dinmont Terrier, Arabian Greyhound, English Foxhound, Finnish Spitz, Thai Ridgeback, Lowland Sheepdog, Bergamasco Sheepdog, Norwegian Lundehund, Swedish Vallhund, and Finnish Lapphund are unique and cherished by discerning dog owners.
