Big dogs aren’t just pets; they’re gentle giants with hearts as big as their size. From towering guard dogs to affectionate family companions, large breeds leave a lasting impression on anyone lucky enough to share their home.
Sadly, many of these incredible dogs are becoming rare, as their size and specialized needs make them challenging for most owners to care for properly.
Royal Canin research shows that large and giant breeds need special attention to support healthy bones and joints as they grow. Despite their size, many have calm temperaments and can thrive as family pets, though energy levels and care requirements vary by breed.
Proper nutrition, exercise, and careful management are key to their well-being.
This blog highlights remarkably large dog breeds, their personalities, care needs, and why they are increasingly rare, showing what makes each one unique.
Wonderful Giant Dog Breeds Rarely Seen Today
1. Tibetan Mastiff
This truly wonderful giant breed is massive, often exceeding 100 pounds with an incredibly dense coat. This majestic size and thick fur helped them survive the high-altitude Himalayas, making them physically imposing and visually stunning dogs.
The Tibetan Mastiff is an ancient guard dog with a fiercely protective nature. They can be dedicated family pets, but their powerful, independent temperament requires firm training and socialization from an experienced owner.
According to PDSA, Tibetan Mastiffs do bark, though how much really depends on their personality and training.
This purebred is rarely seen today because its size requires extensive, secure space to patrol. Their instinct to bark at night and high maintenance needs limit suitable homes, which contributes greatly to their uncommon status.

2. Leonberger
The Leonberger is a wonderful giant dog breed, often called the “gentle lion.” This impressive dog can weigh up to 170 pounds, featuring a thick, water-resistant coat.
The breed originated in Leonberg, Germany, created to resemble a lion. Despite their grand size, their kind disposition makes them truly approachable.

They are excellent family pets and thrive on being included in all family activities due to their sociable nature.

3. Irish Wolfhound
Talk about a giant! The Irish Wolfhound has truly impressive size, standing taller than any other breed, often over 32 inches. Despite their huge, muscular frame, they have a shaggy, rough coat. They were originally bred in Ireland to hunt wolves, which required massive power and speed.
Despite their intimidating height, these giant dogs have a wonderfully gentle spirit and a distinct calm demeanor. They make an excellent companion dog, known for deep devotion and surprising laziness around the house! They are patient and great with kids.
It’s heartbreaking that this amazing large dog is rarely seen today because of their tragically shorter lifespan. According to PetMD, their lifespan is 6 to 8 years. The emotional difficulty of loving a dog with such a short life, combined with the vast space and high financial commitment their size demands, unfortunately limits the number of dedicated owners.

4. Kangal
The Kangal Shepherd Dog is a truly wonderful giant breed, and one of the oldest breeds still around. This dog is exceptionally large, often topping 140 pounds.
They are highly valued as working flock guardians of ancient lineage. While they possess powerful protective instincts, many people call them gentle giants.
In terms of personality, the Kangal is incredibly loyal, intelligent, and affectionate. They are naturally protective and highly territorial, but when properly socialized, they can be reliable with other pets. Despite their massive coat, they are relatively low-maintenance dogs when it comes to grooming.
This capable guard dog is rarely seen outside of Turkey today due to strict export restrictions by the Turkish government. Their specialized needs, requiring vast, open spaces to patrol, and changes in traditional herding practices also contribute significantly to their scarcity.

You will not spot this guardian often today because it never gained much popularity beyond Spain. It needs more space, and the commitment required to handle such a large, independent dog gently reduces public interest.
By nature, Spanish Mastiffs are calm, affectionate, and genuinely devoted. They also show gentle patience with children, building a warm, protective bond. Since they were developed to work on their own, they stay sharp and determined, offering experienced owners a relaxed companion.

It forms a loyal bond with its family and likes to make decisions on its own, so early guidance and a confident owner help shape good behavior.
