Rare Big Dog Breeds Known For Their Creativity
1. Leonberger
The Leonberger is a majestic, rare dog breed from the town of Leonberg in Germany. According to legend, it was first bred in the 17th century by crossing Newfoundlands, Saint Bernards, and Great Pyrenees to resemble the lions on Leonberg’s coat of arms.
Their striking reddish-gold coats and friendly nature quickly made them a favorite among European royalty. Originally companions for nobles, they later became reliable farm helpers and all-around working dogs.
Personality & Temperament
Leonbergers are known for being incredibly loyal and having an affectionate nature. These gentle giants adore their families and are especially good with children. They love affection, enjoy playtime, and are just as happy relaxing on the couch.
Incredibly intelligent and easy to train, they are happiest when given a job to focus on—whether it’s cart pulling, search-and-rescue, or simply staying close to their people.
Fun Facts & Care Tips
Lion-like Look: Males grow a thick mane around the neck, giving them a regal, lion-like appearance.
Big but Gentle: Despite their size, they have a soft, loving personality.
Grooming Needs: Their long, heavy coat requires regular brushing to stay clean and healthy.
Health Watch: They can be prone to joint issues and heart disease, with a short lifespan of about 7 years.
Royal History: Once beloved by European royalty, they nearly went extinct during both World Wars.
2. Black Russian Terrier
The Black Russian Terrier (BRT) is often called “Stalin’s dog”. It is a giant working breed developed in the former Soviet Union during the 1930s. Originally bred by the state-owned Red Star Kennel, the goal was to produce a strong and reliable guard dog for the military and police.
The Black Russian Terrier gained international recognition in 1984 and was officially recognized by the American Kennel Club in 2004.
Personality & Temperament
Don’t be fooled by the word “terrier” — this is no small lap dog. The Black Russian Terrier is large, courageous, and incredibly loyal to its family. Naturally protective with a reserved nature with strangers, they make excellent watchdogs for family life.
Yet, with proper socialization, they can be affectionate and gentle with children. These dogs are intelligent and enjoy having a purpose, whether it’s guarding the home or participating in dog sports.
Fun Facts & Care Tips
Lifespan: Typically 10–14 years, longer than many large breeds.
Health Concerns: Prone to hip and elbow dysplasia and hyperuricosuria. Some may develop progressive retinal atrophy (PRA).
Training: Early socialization and consistent training are crucial to maintaining a balanced protective instinct.
History Note: Once bred only by the Soviet government, the breed slowly spread to Europe and North America after the 1950s.
Big but Calm: Despite their imposing size, they can be gentle giants when raised with love and structure.
3. Irish Wolfhound
The Irish Wolfhound is the tallest dog breed recognized by the AKC. Their ancestors date back to ancient times, but they became popular in the 15th century when they were bred to hunt big game and help control the wolf population in Ireland.
Today, they are admired for their calm nature and striking presence, making them dignified companions rather than fierce hunters.
Personality & Temperament
Despite their size, Irish Wolfhounds are gentle and patient. They are too serene to be fierce guard dogs, but their towering appearance alone is enough to deter strangers.
These dogs are affectionate with their families and characteristically kind with children, though supervision is wise because of their sheer size. Sensitive and eager to please, they respond best to positive reinforcement training, like clicker training and treats.
Fun Facts & Care Tips
Coat Colors: Their rough, hard coat comes in many shades—white, gray, brindle, red, black, and fawn.
Health Watch: Prone to health issues, such as hip dysplasia and life-threatening GDV (bloat).
Lifespan: Short, usually around 6–8 years.
Exercise Needs: They have an active lifestyle and need plenty of mental and physical exercise to stay healthy.
Majestic Presence: Just their size and calm demeanor can make intruders think twice.
4. Neapolitan Mastiff
Dating back to ancient Rome, the Neapolitan Mastiff is a giant, powerful dog with a rich history as both a war dog and a protector of estates. With their loose wrinkles and folds of skin, these dogs were intentionally bred to look “ugly” to deter intruders, according to PetMD.
Personality & Temperament
Despite their fierce appearance, Neapolitan Mastiffs are affectionate and have a good temperament. They are fiercely loyal to their families and naturally protective, making them excellent guard dogs.
These “giant couch potatoes” love long naps in the sun but still need daily exercise and physical stimulation to stay healthy. Consistent, positive reinforcement training helps them manage their strong protective instincts.
Fun Facts & Care Tips
Drool Alert: They drool a lot—keep grooming wipes handy to clean their face and skin folds.
Exercise Needs: Daily walks are important to prevent weight gain.
Gentle Giant: Once fierce war dogs, they now prefer quiet family life.
Size: Though slightly smaller than the English Mastiff, they are still among the largest dog breeds.
5. Scottish Deerhound
The Scottish Deerhound, often called the “Royal Dog of Scotland,” is a unique canine that resembles a big-boned, scruffy Greyhound, according to AKC. Bred centuries ago to hunt giant red deer, this ancient coursing hound was born to run freely across the rugged Scottish Highlands.
Their crisp coat comes in several shades, though breed enthusiasts favor the dark blue-gray. Owning a Deerhound is a truly rewarding experience for those who appreciate their quiet nobility and need for space.
Personality & Temperament
This breed is gentle, sensitive, and full of quiet charm. Their outgoing personality shines when spending time with family, but their independent nature means they can be a little aloof at times. They form deep bonds and don’t like being left alone for long periods.
A confident owner who provides proper care and plenty of exercise is essential, as this hound has a strong instinct to chase and needs safe, fenced areas to run freely. While not ideal for urban living, they can adapt if given enough room and daily activity.
Fun Facts & Care Tips
Coat Care: Their crisp coat still needs regular brushing to manage shedding and prevent matting.
Health Watch: Life expectancy is about 7–9 years; they may be prone to neck pain and hypothyroidism.
Exercise Needs: Built for speed, they need space and supervised play to stay happy and healthy.
Training Tip: Positive reinforcement works best for their sensitive nature.
Family Companion: Despite their size and hunting roots, they are gentle giants who love cozy time indoors.
6. Tibetan Mastiff
The Tibetan Mastiff is an ancient breed. Their thick double coat makes them appear even larger and helps them thrive in cold, snowy weather. This noble dog originated in China as early as 1100 B.C. and was bred to guard monasteries, guard and herd cattle in the Himalayan mountains.
Purina says that in Tibet, they are known as “do khyi,” which means “home guard.” Despite their calm nature, these dogs are powerful and show incredible flexibility when needed, and have a long history as fearless protectors.
Personality & Temperament
Tibetan Mastiffs are intelligent, strong-willed, and have an independent streak. They are naturally protective and can be aloof or even intimidating toward strangers. Early socialization is essential, especially if you have regular visitors.
While they enjoy spending time with their family and can get along with other household dogs if introduced early, they like to make up their own minds and don’t always follow commands blindly. A confident owner who can provide firm yet positive training is a must.
Fun Facts & Care Tips
Coat Care: Their thick double coat sheds heavily once a year. Brush often during shedding season to manage it.
Exercise Needs: Strong and energetic, they need daily walks and enjoy outdoor activities.
Heat Alert: They can overheat in warm climates, so keep them cool in hot weather.

Not for Beginners: Their size and independent nature make them best suited for experienced dog owners.
7. Bloodhound
The Bloodhound is one of the oldest scent-hunting hounds in the world, with ancestors dating back to ancient Greece and Rome. Its name comes from its “blooded,” or aristocratic, lineage—not from any link to aggression.
Refined during the Middle Ages, this ancient breed is famous for an incredible nose with about 230 million scent receptors—roughly 40 times more than humans. Their keen tracking ability has made them a popular breed in hunting and search-and-rescue work.
Personality & Temperament
Bloodhounds are patient, mild-mannered, and gentle with children, though kids should be careful not to tug on their long, floppy ears.
Their calm nature can be mistaken for laziness, but they are active, determined workers when following a scent. They thrive on mentally stimulating activities that challenge their tracking skills and keep them from getting into mischief.
Fun Facts & Care Tips
Grooming: Relatively low maintenance, their short coat requires only weekly brushing to manage shedding.
Bath Time: Regular baths help reduce their natural “doggy” odor.
Ear & Wrinkle Care: Clean ears and facial wrinkles often to prevent irritation or infection.
Tracking Talent: Great choice for law enforcement to find people or lost items.
