When you picture a wolf, you probably imagine one of the largest wild canines roaming the forest. But did you know that several dog breeds actually outweigh and tower over their wild cousins? These gentle giants combine impressive size with loyal companionship, proving that bigger can indeed be better when it comes to four-legged friends.
Size comparisons are based on average adult weights. Grey wolves typically weigh between 27 to 79 kilograms, depending on subspecies and region. Individual dogs may vary in size based on genetics, diet, and health.
1. English Mastiff
Holding the record as one of the heaviest dog breeds on Earth, the English Mastiff can tip the scales at over 100 kilograms. That’s significantly more than even the largest grey wolves!
Despite their intimidating bulk, these dogs are famously calm and affectionate with family members. They were originally bred in England to guard estates and hunt large game, but today they’re more likely to be found snoozing on the couch than chasing prey.
2. Saint Bernard
Famous for rescue missions in the Swiss Alps, Saint Bernards are legendary for their strength and endurance in harsh conditions. Weighing up to 90 kilograms, they dwarf most wolves by a considerable margin.
Their thick, weather-resistant coats helped them navigate treacherous mountain passes while searching for lost travellers. Today, these lovable giants are cherished family pets known for their patient, protective personalities around children.
3. Tibetan Mastiff
With a lion-like mane and fierce guarding instincts, the Tibetan Mastiff was bred to protect livestock from predators like wolves and leopards in the Himalayas. Males can reach 82 kilograms, making them formidable opponents for any wild canine.
These independent thinkers are deeply loyal to their families but remain naturally wary of strangers. Their thick double coat allows them to thrive in freezing temperatures where other breeds would struggle.
4. Great Dane
Towering over nearly every other breed, Great Danes are the skyscrapers of the canine world. While they may not always outweigh wolves, their height is absolutely staggering, with some standing over 80 centimetres at the shoulder.
Originally bred in Germany to hunt wild boar, these elegant giants are surprisingly graceful despite their size. Their friendly, affectionate nature earned them the nickname “gentle giants,” and they adore being close to their human families.
5. Irish Wolfhound
As the name suggests, Irish Wolfhounds were specifically bred to hunt wolves in Ireland centuries ago. Standing up to 86 centimetres tall and weighing around 70 kilograms, they have both the size and speed to match their quarry.
Despite their hunting heritage, modern Irish Wolfhounds are remarkably calm and friendly. They form strong bonds with their families and are known for being surprisingly quiet and easygoing indoors, though they still need plenty of exercise.
6. Anatolian Shepherd
For thousands of years, Turkish shepherds relied on these powerful dogs to defend their flocks from wolves, bears, and other predators. Weighing up to 68 kilograms, Anatolian Shepherds are fearless protectors with lightning-fast reflexes.
Their independent nature means they can make decisions without human guidance, a crucial trait when guarding livestock in remote areas. While devoted to their families, they require experienced owners who understand their strong-willed, protective instincts.
7. Caucasian Shepherd Dog
Looking more like a bear than a dog, the Caucasian Shepherd was bred in the Caucasus Mountains to protect sheep from wolves and thieves. Males can exceed 90 kilograms, making them one of the most imposing breeds alive.
Their fearless temperament and powerful build made them invaluable guardians in harsh mountain climates. These dogs require firm, consistent training and aren’t recommended for first-time owners due to their strong territorial instincts and protective nature.
8. Dogo Argentino
Developed in Argentina during the 1920s, this muscular breed was designed to hunt big game like wild boar and puma. Weighing around 45 kilograms with dense muscle mass, Dogo Argentinos are incredibly strong for their size.
Their all-white coat helps hunters spot them in dense brush, while their courage and tenacity made them effective pack hunters. They require extensive socialisation and training but form intensely loyal bonds with experienced, active owners who appreciate their energy.
9. Boerboel
South African farmers developed the Boerboel to protect homesteads from dangerous predators like leopards and hyenas. Males can weigh up to 90 kilograms, combining massive strength with surprising agility and speed.
Their name means “farmer’s dog” in Afrikaans, reflecting their deep roots in rural South African culture. Boerboels are confident, intelligent guardians who need firm leadership and plenty of socialisation to channel their protective instincts appropriately.
10. Kangal
Turkey’s national dog, the Kangal, has protected livestock from wolves for centuries with legendary effectiveness. Weighing up to 66 kilograms with powerful jaws, they’re considered one of the best livestock guardian breeds worldwide.
Their calm, controlled temperament means they don’t waste energy on unnecessary aggression, but they’re absolutely fearless when defending their charges. Kangals form deep bonds with the animals they protect, treating them like family members worth defending at any cost.
11. Pyrenean Mountain Dog
Known as the Great Pyrenees in North America, these magnificent white guardians have protected sheep in the Pyrenees Mountains for thousands of years. Males can weigh around 60 kilograms, with thick coats making them appear even larger.
Their weather-resistant double coat allows them to work comfortably in freezing mountain conditions year round. Pyrenean Mountain Dogs are naturally nocturnal, preferring to patrol and guard their territory during nighttime hours when predators are most active.
