Imagine strolling through a dog park and spotting a pup so striking, you can’t help but do a double-take—yet hardly anyone knows what kind of dog it is. That’s the magic of uncommon big dog breeds.
While most of us can easily name a handful of popular dogs, there’s a whole world of gentle giants that quietly capture hearts without making the “most popular” lists.

These lesser-known large breeds aren’t just about size; many have fascinating backstories—some were once bred for tasks that barely exist today, from guarding ancient homesteads to pulling loads across rugged terrain.

Uncommon Big Dog Breeds Worth Considering
1. Otterhound
The Otterhound is a large hunting dog that comes from England. It was originally bred in Medieval times to hunt otters, which is how it got its name. These dogs are built for both land and water with their rough double coat and uniquely webbed feet.
They also have an incredibly powerful nose that can follow a scent trail—even underwater. Their waterproof coat makes them just as happy splashing in rivers as running along trails.
Personality & Temperament
Amiable and boisterous, the Otterhound is full of life yet easygoing. They’re affectionate and even-tempered, making them wonderful family companions.
This breed loves outdoor adventures and is great with kids. Playful and fun, they enjoy activities on both dry land and in the water. Their independent nature means they can keep themselves entertained, yet they’re always thrilled when their people come home.
Rare and Remarkable
Otterhounds are among the rarest British dog breeds, with only about 600 left in the world. Their numbers dropped after otter hunting was banned in the UK in 1981.
Today, they are considered a vulnerable native breed. But for those lucky enough to find one, the Otterhound offers loyalty, a friendly spirit, and a unique connection to history.
2. Leonberger
The Leonberger is a giant dog that originated in the town of Leonberg, Germany. PetMD mentions that legend says it was created in the 17th century by crossing Newfoundlands, Saint Bernards, and Great Pyrenees to resemble the lion on the town’s coat of arms.
This lush-coated breed quickly became a favorite of European royalty and also worked on farms.
Personality & Appearance
Despite their huge size, Leonbergers are known for their gentle and patient nature. They have a medium-long waterproof coat, triangular ears, a bushy tail, and a striking black mask framing warm brown eyes.
Males often grow a dramatic, lion-like mane around the neck and chest. Their easy, elastic gait and graceful presence give them an almost aristocratic look.
Loyal and Hardworking
Nicknamed “Leos,” these dogs are intelligent, loyal, and calm. They have an instinct for work and are often used in search-and-rescue today.
Leonbergers make excellent family pets and are friendly yet alert watchdogs. They do need plenty of space to play, regular brushing to maintain their dense coat, and lots of love and attention from their families.
3. Komondor
The Komondor is a massive Hungarian livestock guardian known for its striking corded white coat. These long, rope-like cords cover the dog from head to tail, giving it the look of a walking mop.
Originally bred to guard sheep, the Komondor’s unique coat helped it blend with the flock and protect against harsh weather.
Personality & Traits
Komondorok are powerful and confident but also calm and devoted to their families. Their natural guarding instincts make them excellent watchdogs. While they are protective, they are also gentle with those they love.
Regular exercise and early socialization help them stay happy and well-balanced. Their special coat requires careful grooming to maintain those signature cords.
Rare and Remarkable
This rare breed stands out wherever it goes and remains a symbol of Hungarian heritage. Strong yet graceful, the Komondor is both a hardworking flock protector and a loyal family dog. For those who can handle their grooming needs and give them plenty of space, these “mop dogs” are truly unforgettable.
4. English Foxhound
The English Foxhound is an old hunting breed from England, recognized by the AKC in 1909. It was bred to hunt foxes in large packs and is built for stamina and speed. This strong and sturdy hound has long, straight legs and a perfectly level back.
Personality & Traits
This breed combines beauty, balance, and utility. English Foxhounds are active, loyal, and gentle companions. They are pack-oriented and driven by a powerful hunting instinct, which can sometimes make training a challenge.
With a sociable and affectionate nature, they enjoy being around other dogs and people. They thrive best in homes where they get plenty of exercise and outdoor adventures.
Rare and Noble
Though rarely kept as house pets today, English Foxhounds remain admired for their grace and strength, once compared to an old Greek statue for their classic good looks. With proper socialization and space to roam, they can be both noble hunters and affectionate family companions.
5. Chinook
The Chinook is a rare sled dog breed that originated in New Hampshire. Its name, pronounced “Sha-Nook,” means “warm winter winds” in Inuit. This powerful yet gentle breed was created by an explorer in the late 1920s, combining the strength of freighting dogs with the speed of racing sled dogs.
Personality & Traits
Chinooks are large and muscular, built to handle cold weather with their thick double coats. They are hardworking, highly trainable, and eager to please.
Calm and affectionate, they get along well with children and other dogs, making them excellent family companions. These intelligent dogs need mental stimulation and regular activity to stay happy.
Rare and Remarkable
Today, the Chinook is considered one of the world’s rarest breeds, with only about 1,200 dogs in existence. They continue to excel in sledding but are also used in search and rescue, agility, obedience, and herding.
With a lifespan of 13–15 years, the Chinook is a hardy and loyal breed that thrives on adventure and family life.
6. Azawakh
AKC says that the Azawakh is a rare and elegant sighthound from West Africa. Named after the Azawakh Valley of the Saharan Sahel, this ancient breed was once used by nomadic tribes like the Tuareg to guard livestock and chase game such as gazelles and hares.
Personality & Traits
Slim and graceful, Azawakhs have a light, effortless gait and short, fine coats in many colors—brindle, white, black, dark red, gray, brown, and parti-color. Indoors, they are calm and reserved, but outdoors, they have tremendous speed and endurance.
These beautiful dogs bond deeply with their families and are naturally protective, yet they remain aloof with strangers. A strong prey drive means they need a tall fenced yard and plenty of daily exercise.
Care & Companionship
Azawakhs thrive on running and long walks and need consistent training and socialization from a young age. Their sleek coat is easy to care for with regular brushing and a monthly bath.
With a lifespan of 12–15 years, this loyal and intelligent breed makes a fiercely protective companion and an ideal partner for active owners who love to stay on the move.
7. Estrela Mountain Dog
The Estrela Mountain Dog is one of Portugal’s oldest and most impressive breeds. Originating in the rugged Estrela Mountains, these dogs were bred to guard livestock from predators and thieves.
Their size, strength, and natural alertness made them excellent farm protectors and even trusted police dogs. Despite their powerful presence, these working dogs are gentle giants with a loyal and nurturing nature.
Personality & Traits
Estrelas are calm, courageous, and deeply devoted to their families. They form strong bonds and often choose one special person as their favorite. While they are protective and naturally wary of strangers, they remain loving and gentle with children.
They are independent thinkers, so socialization and training from an early age are important to keep their strong-willed nature well-balanced.
Loyal Guardian
This rare breed is both a faithful house guard dog and an excellent companion. Once an Estrela bonds with you, the connection lasts a lifetime.
Their combination of protective instincts and warm personality makes them both a dependable watchdog and a loving family member—truly a protector and playmate in one.
