1. English Mastiff
Officially crowned the largest dog breed in the world, the English Mastiff holds a legendary place in canine history.
A remarkable Mastiff named Zorba tipped the scales at an astounding 142.7 kilograms and stood 27 inches tall in 1981, earning a permanent spot in the Guinness Book of Records.
Despite their intimidating bulk, these massive dogs are known for being calm, affectionate, and surprisingly lazy around the house.
They adore their families and make excellent watchdogs simply by their presence alone.
2. Great Dane
When it comes to sheer height, no breed can match the spectacular Great Dane.
Zeus, a Great Dane who measured an incredible 44 inches from paw to shoulder, claimed the title of world’s tallest dog.

Their playful, loving nature makes them fantastic companions despite needing plenty of space.
They’re often called the “Apollo of dogs” for good reason.

Picture a dog strong enough to trudge through metres of snow while carrying supplies to stranded travellers.
That’s the Saint Bernard, originally bred by monks in the Swiss Alps for mountain rescue missions.
Weighing up to 91 kilograms, these powerful dogs saved countless lives over centuries with their incredible sense of direction and stamina.
Their thick, weather resistant coats and massive paws made them perfect for harsh alpine conditions.
Today, they’re cherished as loyal, protective family members.
4. Irish Wolfhound
With a history stretching back thousands of years, the Irish Wolfhound once hunted wolves and elk alongside Celtic warriors.
Standing up to 35 inches tall, these sighthounds possess remarkable speed despite their size.

Their shaggy, rough coats and soulful eyes give them a distinctly noble appearance.
Romans were so impressed they exported them throughout their empire.
5. Leonberger
Bred specifically to resemble the lion on the town crest of Leonberg, Germany, this breed certainly achieves its majestic goal.

They’re also surprisingly athletic swimmers with webbed feet.
Families with children particularly appreciate their protective yet tender hearted nature.

Originally from the Canadian island sharing their name, Newfoundlands are legendary water rescue dogs with natural lifesaving instincts.

Their sweet, docile personality contrasts beautifully with their imposing size.
They literally drool with affection for their families.

High in the Himalayan mountains, Tibetan Mastiffs have guarded monasteries and livestock for thousands of years.
These independent, intelligent dogs can weigh over 80 kilograms and sport incredibly thick coats to survive freezing mountain temperatures.

Unlike many giant breeds, they’re quite aloof and protective rather than overly affectionate.
One sold for nearly two million dollars in China.

Hailing from Turkey’s harsh Anatolian plateau, these livestock guardians were bred to fend off wolves, bears, and even cheetahs.
Anatolian Shepherds can reach 65 kilograms and possess remarkable endurance, capable of patrolling vast territories for days.
