1 – The Neapolitan Mastiff
Measuring in at 7 feet tall and weighing as much as 230 pounds, you’d better hope your doorways are extra wide if you want to invite one of these giants into your home. For reference, that’s around three times bigger than a Golden Retriever! Originally bred to protect livestock, Neapolitan Mastiffs can also be trained to guard property or act as service dogs.
2 – Tibetan Mastiff
With a rare blue-black tongue and piercing eyes, you’ll want to keep an eye on your pets after seeing these giant, intimidating beasts. The Tibetan Mastiff has been known to grow up to 300 pounds with a lifespan of 10-12 years. They are one of the biggest dog breeds in existence and make great guard dogs. Not only are they big but they are built like a tank as well; their muscular build makes them dominant among many other canine species.
3 – Great Dane
The Great Dane is a giant, muscular dog, often nicknamed the Apollo of dogs for its handsome looks. They are commonly referred to as gentle giants or as Kind Gentle Giants because of their affectionate personality.
The Great Dane should be well socialized with people and other animals from an early age. This giant breed is considered by many to be a good family pet, but due to its large size they may not be suitable for smaller homes.
4 – St. Bernard
Massive, furry and endearingly sweet, St. Bernards are one of most iconic dog breeds in history. The world’s biggest dog breed was bred to be a working dog, helping lost travelers in Switzerland’s Alps by carrying food, medical supplies and equipment over snowy terrain.
This gentle giant can live up to 12 years old. Despite its large size — 90 pounds is average — a St. Bernard is surprisingly mild-mannered with people and gets along well with other dogs and cats alike.
5 – Irish Wolfhound
The Irish Wolfhound is also one of our favorite giant dog breeds. A wolfhound, by definition, should not be confused with a coyote or domestic dog; these dogs are twice as big as any other breed in existence!
They weigh between 120 and 150 pounds and stand at about 2 feet tall. If you’re looking for a friend who’s close to your size and likes to go running with you, don’t look past an Irish Wolfhound!
6 – Leonberger
Also called Lion dogs, these gentle giants were originally bred as hunting companions and watchdogs in Germany. They’re extremely affectionate and loyal, with a calm demeanor.
The Leonberger is a giant breed that matures at 30 to 40 inches tall and can weigh anywhere from 130 to 175 pounds! Their long hair needs regular brushing to keep it clean and prevent tangles. This big dog also has big slobbery kisses!
7 – Scottish Deerhound
The Scottish Deerhound stands up to 29.5 inches tall and can weigh as much as 130 pounds, making it one of the biggest dog breeds in existence.
Despite its massive size, it’s a gentle dog that rarely barks or bites.
Known for its speed, stamina and agility, deerhounds have been used as hunting dogs since prehistoric times by Celtic tribes such as Scotland’s fierce Dalriadans.
8 – Newfoundland
This giant dog breed comes from Canada and was bred to help fisherman pull nets in icy waters. This working dog can weigh up to 150 pounds and is extremely kind, loyal, and protective. Newfoundland dogs are also very sweet but can sometimes be stubborn. They require a lot of attention due to their large size so they’re not best for smaller homes or apartments.
9 – Greater Swiss Mountain Dog
Sometimes called a Swiss Mountain Dog, Greater Swiss Mountain Dogs are giant working dogs bred for herding cattle. The breed originated in Switzerland around 1850 from ancient crosses between Roman Mastiffs and local breeds. These protective canines are loyal to their masters and will fight to defend them if necessary.
According to Guinness World Records, they are currently among the largest dog breeds in existence today. Their size makes them suitable as guard dogs, but they’re friendly enough with humans that they can also be family pets.
10 – Dogue de Bordeaux
Although many people prefer their dogs small, some dog owners swear by giant breeds. No list of giant dog breeds would be complete without mention of Dogue de Bordeauxs. These giant dogs stand up to 27 inches tall at their shoulder and can weigh anywhere from 125 to 175 pounds or more!
Originally bred for working in packs and hunting boar, Dogue de Bordeauxs are big and powerful but also great companions for active families who enjoy hiking or biking together.
What’s the biggest dog in the world?
The biggest dog in recorded history is a huge mastiff named Zorba. Zorba, who was raised by Joel and Sandy Faison of Rome, Georgia, tipped the scales at 343 pounds when he died.
Not only did he weigh more than 100 pounds more than any other recorded dog but he was also taller than many NBA players.
The average Great Dane only weighs around 150 pounds, which means that Zorba was approximately six times larger than an average Great Dane.
