Loyalty is one of the greatest gifts a dog can offer, and it’s a quality that has earned them the title of humankind’s best friend for centuries.
While most dogs display some level of devotion, certain breeds take loyalty to a whole new level, forging unshakable bonds with their families and standing as lifelong protectors.
What’s fascinating is how this loyalty often ties back to a breed’s history. Dogs originally bred for guarding or herding tend to be especially committed to their people, often demonstrating protective instincts that extend beyond affection.
Their dedication can be so strong that they’re willing to put themselves in harm’s way to keep loved ones safe, proving just how powerful the canine-human connection can be.
In this article, we’ll shine a light on some of the rarest dog breeds in the world that embody loyalty in extraordinary ways.
With nearly 200 recognized breeds worldwide—and countless others outside the spotlight—you might just discover a new favorite among these rare yet incredibly devoted companions.
Rare Dog Breeds That Prove Loyalty Is Forever
1. Mudi
The Mudi (pronounced “moodie”) is a medium-sized herding dog from Hungary, sometimes referred to as the Hungarian farm dog. This rare breed traces its roots to the 19th century and is believed to have developed naturally from crosses of the Puli, Pumi, and German Spitz.
With only a few thousand Mudis worldwide, most found in Hungary and Finland, they remain one of the least-known yet most versatile herding breeds.
AKC says its courage helps it to handle even the most stubborn livestock, and the breed is a loyal guardian of property and family without being overly aggressive.
What makes the Mudi stand out in loyalty is the deep connection it forms with its family. It is one of the most loyal dog breeds. These dogs are naturally protective and attentive, often staying close to their people and serving as reliable guardians without being overly aggressive.
Their intelligence and devotion mean they’re quick to learn, especially when training is positive and engaging.
Because of their history as all-purpose working dogs, Mudis are happiest when given a job to do, whether it’s herding, agility, or obedience. This need for purpose strengthens their bond with their owners, as they thrive on teamwork and shared activity.
Their loyalty can also be seen in how they handle challenges. Patient, adaptable, and eager to please, Mudis often go beyond simple obedience, showing intuition and sensitivity toward their owners’ emotions.
Fun Fact: The Mudi is not only skilled at herding but has also earned recognition in search-and-rescue work in both Finland and the U.S., highlighting its intelligence and dedication.
2. Lagotto Romagnolo
The Lagotto Romagnolo, often called the “truffle dog,” is an ancient Italian water breed once prized for duck hunting. With its dense, curly, waterproof coat and expressive eyes, this medium-sized dog is not only striking but also full of charm.
Though rare outside of Italy, the Lagotto has gained recognition for its affectionate and loyal temperament. PetMD says Lagotti are energetic without being overly hyper, and this breed is a natural problem-solver that loves to please the people they care about.
What makes the Lagotto a lifelong partner is its deep devotion to family. These dogs thrive on companionship and build strong, lasting bonds with their people. They are affectionate without being overly demanding, always eager to both join on adventures and curl up afterward.
Highly intelligent and quick to learn, Lagotti love engaging activities. Mental challenges such as puzzle games, scent training, or advanced obedience keep them sharp while strengthening their bond with owners.

3. Plott Hound
The Plott Hound, North Carolina’s state dog, is the only coonhound breed not descended from foxhounds. Instead, it traces its lineage to German hunting hounds brought to America by the Plott family in the 1700s.
WebMD says Plott Hounds are large scent hounds that were bred specifically for hunting boar. With its muscular build, brindle coat, and long legs built for stamina, this breed is as striking as it is capable.
Loyalty defines the Plott Hound. These loyal dogs form deep attachments to their families and often demonstrate affection by sticking close to their people. Their alert nature makes them attentive companions who watch over loved ones with devotion, even if their primary role was originally big-game hunting.
Their dedication goes beyond simple affection. Plotts thrive when given purpose—whether as jogging partners, guardians, or simply shadowing their owners throughout daily life. They require consistent exercise and mental stimulation to keep their loyalty channeled into positive behaviors.
What sets them apart is their fearlessness, combined with eagerness to please. Originally bred for challenging hunts, they’ve carried that same courageous spirit into modern homes, showing love through protection and constant presence.
Fun Fact: The Plott family’s careful breeding in western North Carolina established the Plott Hound as a prized hunting dog, admired nationwide by the 1930s for its courage and tenacity.
4. Otterhound
The Otterhound, a rare British scent hound, was originally bred to track and hunt otters along rivers. With fewer than 1,000 dogs worldwide, it is considered one of the UK’s most vulnerable native breeds.
Distinguished by its rough, water-resistant double coat, webbed feet, and strong build, the Otterhound was perfectly designed for swimming and endurance.
Despite their hunting background, Otterhounds are known for their affectionate, fun-loving nature. They bond deeply with their families and thrive when included in daily activities, proving their loyalty through constant companionship.
Their clownish personality brings joy to households, yet they remain steadfastly protective of those they love. These dogs are particularly trusted companions because of their gentle temperament with children and their ability to adapt to family life.
While lively as puppies, with consistent training, they learn to channel their energy into play and affection, rather than chaos. Their sensitive side makes them especially attuned to their people’s emotions.
Another mark of their loyalty is their eagerness to stay close, whether lounging indoors or joining outdoor adventures. Though rare, those lucky enough to own an Otterhound gain a devoted friend for life.
Fun Fact: Fans of the breed affectionately call Otterhounds the “clowns of the hound group” due to their humorous and playful demeanor.
5. Dandie Dinmont Terrier
The Dandie Dinmont Terrier, a rare breed originating from the border of England and Scotland in the 1700s, was originally bred to hunt otters and badgers. With its long, low body, silky head hair, and soulful eyes, this terrier stands out both for its appearance and its dignified charm.
Loyalty defines the Dandie’s nature. While not naturally a pack dog, it forms an unshakable bond with one special person, though it can also integrate lovingly into a family setting. This deep attachment is what makes them remarkable companions, always eager to stay close to their people.
Protective yet calm, the Dandie is an excellent watchdog without being overly noisy or high-strung. Its deep bark surprises many and underscores its role as a vigilant little guardian, keeping a watchful eye on its home and loved ones.

Fun Fact: The Dandie Dinmont Terrier is the only recognized dog breed named after a fictional character—Dandie Dinmont from Sir Walter Scott’s 1814 novel Guy Mannering, as noted by the BBC.
6. Cirneco dell’Etna
The Cirneco dell’Etna, sometimes simply called Cirneco, is an ancient sighthound that hails from the slopes of Sicily’s Mount Etna. Resembling a smaller version of the Pharaoh Hound, this breed is slender, graceful, and built for speed.
With upright ears, a sleek tan coat, and a dignified presence, it has remained largely unchanged for centuries.
What makes the Cirneco cherished by devoted owners is its unwavering loyalty. While independent in spirit, this dog develops strong emotional bonds with its family. Owners often describe them as affectionate companions who thrive on closeness, showing a quiet, unwavering devotion that endures through the years.
Despite their hunting background, this loyal breed adapts surprisingly well to home life. They are calm and low-maintenance indoors but burst with energy outdoors, eager for runs or long walks. This balance between athletic drive and affectionate nature makes them both capable hunters and loving housemates.

7. Polish Lowland Sheepdog
The Polish Lowland Sheepdog, affectionately known as the PON (from its Polish name, Polski Owczarek Nizinny), is a medium-sized, shaggy-coated herding breed with deep roots in Poland.
Its long double coat, often covering the eyes, gives it a distinctive, rustic charm while protecting it from harsh weather. Known for adaptability, this sturdy herder has been a fiercely loyal farm companion for centuries.

These dogs display a rare mix of intelligence and fierce loyalty, allowing them to work independently yet remain devoted to their owners. They are clever problem-solvers, always eager to help, which only deepens their bond when included in daily family life.
Because they are naturally alert and protective, PONs also serve as excellent watchdogs. However, their love for companionship balances this trait, ensuring they remain gentle, affectionate, and faithful household members.
Fun Fact: The Polish Lowland Sheepdog’s keen memory is legendary—once it learns a task or a person, it rarely forgets.

While famous breeds like the German Shepherd, Golden Retrievers, and Labrador Retriever are well known as service dogs, therapy dogs, and great family dogs, these rare breeds prove that steadfast dedication can also be found in other dogs often overlooked.

These rare breeds, much like their more popular counterparts, thrive as family companions and cherished protectors. In the end, every devoted furry friend reminds us that loyalty isn’t just a trait—it’s the timeless bond that makes dogs extraordinary.
