What is the largest dog breed in America?

The Great Dane is the largest of dog breeds. Males can reach 32 inches in height and weigh up to 175 pounds while females measure up to a height of 30 inches and can weigh between 110 and 140 pounds. But while their size may be intimidating, these dogs make great family companions.

Giant dogs or extra large dog breeds are large and in charge—of your heart. Despite their ginormous and intimidating size, they are teddy bears on the inside with their human families. Many giant dog breeds are in the working group, meaning they guard, protect or serve in some way. Given that mindset, they tend to be remarkably loyal and affectionate with their humans, but often aloof with strangers—at least until proper introductions are made. Giant dog breeds take up a lot of square footage at home or in the car and it can be challenging to maintain control of the leash if you need to reign them in or coax them along if they decide to do things their own way. The gorgeous and stately breeds featured below are 100 pounds or more. Keep in mind the lower weight range is for females and the higher end is males.

Meet the Tosa, the largest Japanese dog breed, according to the AKC. These days the Tosa basks in family life. The Tosa takes its role as the stately and vigilant guardian of the family seriously, yet, it is calm, collected, and peaceful. A properly trained and socialized Tosu is very affectionate with its family but naturally suspicious and aloof with strangers. Due to their unfortunate history of dogfighting, they might not take too kindly to another dog they meet on the street or one that visits your home. However, if a Tosa is raised with another family dog, there’s a better chance of living peacefully. Breed OverviewHeight: 12.5 to 23.5 inches, at the shoulder Weight: 100 to 200 pounds Life expectancy: 10 to 12 yearsDevidDO/Getty Images Are you inviting a lion or a dog to share your home with? It’s hard to tell with the Tibetan mastiff’s formidable size and mane of thick, dense fur. As a working group member, it veers on the side of being a large-and-in-charge independent thinker and guardian. It has a strong sense of self and confidently assumes it is an equal, not a pet. Yet, the Tibetan Mastiff is mellow, calm, and very affectionate with his human family and depends on their companionship to be happy and stay out of mischief. If they’re apart and alone from you for too long, they’ll find ways to entertain themselves that aren’t constructive. Breed OverviewHeight: 24 to 26 inches, at the shoulder Weight: 70 to 150 pounds Life expectancy: 10 to 12 yearsMike Clews/Getty Images You’ve probably already thought about if you have enough space for a huge dog breed, but there are a few more essential things you should consider before adopting a giant dog breed. “A dog who weighs 100 pounds eats almost five cups a day of commercial dog kibble; then add about 1/3 cup more for every 10 pounds over 100 pounds,” says veterinarian Lyndsey Larson, VMD, ABVP, VCA Firehouse Animal Hospital in Denver. And because of their size, they’ll also require more medicine, including flea and tick preventatives. These are just two weighty factors to consider when thinking about how much it will cost to own a dog. Smaller dogs generally reach their full growth at around 12 months. Giant dog breeds take their time reaching their adult weight, reaching maturity between 18 to 24 months old. Behavior and training challenges are magnified when you have a huge dog, so training during the impressionable puppy stage is essential. “A good rule of thumb is to get a large breed pet into a training program and support those good habits at home between the ages of 16 weeks to one year,” advises Dr. Larson. Although the reasons aren’t entirely clear, most giant dog breeds have shorter life spans. They age more quickly, thus developing age-related diseases earlier, such as osteoarthritis, makings it difficult for them to get around or climb stairs. “Plan ahead to help your pet, as some giant breeds require assistance with harnesses and some lifting and assistance to get around as they age or if they become injured,” says Dr. Larson.

Animals Pets 9 of the World’s Largest Dog Breeds By Jaymi Heimbuch Jaymi Heimbuch Twitter Writer California Polytechnic State University, San Luis Obispo Jaymi Heimbuch is a writer and photographer specializing in wildlife conservation. She is the author of The Ethiopian Wolf: Hope at the Edge of Extinction. Learn about our editorial process Updated September 22, 2021 Out of the hundreds of dog breeds found around the world, some qualify as a giant breed. Mikkel Bigandt / Shutterstock Share Twitter Pinterest Email Animals Wildlife Pets Animal Rights Endangered Species The range of size, shape, color, personality, and purpose for which dogs are bred is jaw-dropping. Over centuries, different dogs in different geographic locations have been honed by humans to play certain roles, from hunter to guardian, from herder to companion. For some of these breeds, size has been a significant player in the search for perfection, whether that was to hunt bigger or faster game or guard a home with more intimidation, or even just to have the mass to survive in freezing locations. Of the hundreds of dog breeds around the world, here are nine of the largest. Millions of pets (including many purebreds) are available to be adopted from shelters. We always recommend adoption as a first choice. If you’ve decided to buy a pet from a breeder, be sure to choose a responsible breeder, and always avoid puppy mills. 1 of 9 Great Dane On average, Great Danes stand around 28-30 inches tall. Elsa Hoffmann / Shutterstock The Great Dane is widely recognized as the largest dog breed by the American Kennel Club, at least in terms of height. The Great Dane is a breed of German origin and its German name of Deutsche Dogge means German mastiff. However, before setting down official roots in Germany, the dogs that eventually became the Great Dane breed came from a crossbreed between English mastiffs and Irish wolfhounds. Though they aren’t the heaviest dogs, reaching around 100-120 pounds, they are among the tallest. The average Great Dane stands around 28-30 inches tall but often they can be taller. The world record holder for tallest dog was a Great Dane named Zeus who stood an astounding 44 inches tall. However, these big dogs trade longevity for their size, and live only to be between 6 to 8 years old. Zeus died of old age at just 5 years old. For a better understanding of their height, this Great Dane poses with a small dog standing under her. Dmussma / Shutterstock Though the Great Dane is typically considered the largest of all dog breeds, we’re going to look at a few other breeds that give this one a run for its money, including one breed that is actually even taller. 2 of 9 Neapolitan Mastiff This breed comes in several colors including black, blue, mahogany and tawny. Stanimir G.Stoev / Shutterstock Mastiff breeds are certainly among the largest dog breeds in terms of sheer mass. The Neapolitan mastiff originated in southern Italy. Used as a guard dog, the average male mastiff stands between 26-31 inches tall and weighs a hefty 150 pounds. Females are usually a little smaller, standing a few inches shorter and weighing around 110 pounds. This breed is known for being fearless and protective of home and family, making it an ideal guard dog — but not an ideal warning system. Mastiffs tend to be quiet, and are known for sneaking up on intruders rather than barking to warn them off. Because of the breed’s protective nature, you certainly don’t want to stand between these dogs and their family, which makes this dog a breed only for owners well versed in dog training and able to put in the extensive time needed for socialization. 3 of 9 Scottish Deerhound nemoris / Getty Images Going back to the leggy breeds, the Scottish deerhound gives away its purpose and origin in its name. Originating in Scotland well before recorded history, the breed is a courser, once used to hunt red deer and easily chasing down its prey. They are larger and heavier than greyhounds but are built similarly, with a lanky body meant for speed. Deerhounds can stand as tall as 32 inches and weigh as much as 110 pounds. Though they aren’t used for deer hunting today, the breed is kept alive by enthusiasts who use them for show and in some places, lure coursing: 4 of 9 Irish Wolfhound Ashva / Getty Images Like the Scottish deerhound, the Irish wolfhound was bred to be a courser, and was indeed originally used to chase down wolves. Developed from war hounds into a dog used for hunting and guarding, the Irish wolfhound is ancient and may have been brought to Ireland as far back as 7000 B.C. Though their primary use was hunting, today’s dogs are fairly quiet and reserved, intelligent and easygoing. The wolfhound wins by inches as the tallest dog breed. DragoNika / Shutterstock The Irish wolfhound is the tallest of all dogs, even the Great Dane. According to breed standard, the minimum height should be 32 inches for males and 30 inches for females. That’s just the minimum. Males often stand as tall as 34-35 inches and weigh upwards of 140 pounds. And though the English mastiff is as tall as a miniature horse, the Irish wolfhound is equal to a donkey. 5 of 9 Dogue de Bordeaux The Dogue de Bordeaux was the breed of dog that starred alongside Tom Hanks in the film ‘Turner and Hooch.’. otsphoto / Shutterstock The Dogue de Bordeaux goes by several other names, including the Bordeaux mastiff, French mastiff, and Bordeauxdog. But this breed, by any other name, still stands as massive. Though other breeds, from the poodle and French bulldog to the Great Pyrenees and Basset hound may be more famous breeds of French origin, the Dogue de Bordeaux is one of the most ancient breeds of France. The Dogue de Bordeaux stands between 23-27 inches tall and weighs between 99-110 pounds. But though it is fairly average as far as mastiff breeds go, it does have one thing that sets it apart: It is reported to have the largest head of any canine in relation to body size. Unlike the Neapolitan mastiff, the Bordeauxdog has been used for more than simply guarding house and home, though that was also in its job description. These dogs also were used for everything from watching over flocks to pulling carts. It has historically been a true working dog and a jack of all trades — at least, as far as dogs go. The breed is active and energetic outdoors, but once inside is, well, mellow to say the least. If you’re a Bordeauxdog owner and wondering if you should let your pet sleep on the bed, the answer is: Only if you don’t mind sleeping somewhere else. Vitaly Titov & Maria Sidelnikova / Shutterstock 6 of 9 Newfoundland With heavy bones and big muscles, the Newfoundland is a powerful swimmer and a great water rescue dog. Yan Wen / Shutterstock The Newfoundland is a working dog from, you guessed it, Newfoundland. Unlike many larger breeds, the Newfie wasn’t bred to be a guard dog. Instead, its purpose was originally to help fishermen. The big, muscular dogs are able to haul nets and lines from boats, pull carts, and, most importantly, fetch anything that falls overboard, including people. The breed is an exceptional water dog and strong swimmer, and there have been many rescues of people out at sea credited to these big, gentle-natured dogs. Newfoundland dogs stand an average of 26-28 inches tall and weigh as much as 150 pounds. They look even bigger because of their thick double coat, which keeps them warm even in icy water. 7 of 9 English Mastiff English mastiffs have set the record for heaviest dog ever recorded. Kachalkina Veronika / Shutterstock The English mastiff is one of the largest dog breeds recognized by the American Kennel Club. Growing to a height of 30 inches, these dogs can weigh as much as 230 pounds. As a Great Dane holds the record for tallest dog, an English mastiff once held the record for largest. In 1989, an English Mastiff named Aicama Zorba—weighing 343 pounds—held the title of the heaviest dog. Their size is a significant part of the breed’s past purpose, which included blood sports such as baiting bears, bulls and lions. Today, however, they are simply gentle giants, letting those courageous and fearless aspects of the breed’s temperament sit on the back burner while the mellow, even-tempered and loyal sides come forward. They can make excellent family dogs as they are so easy-going. So if your kids are asking for either a dog or a pony, well… it’s not like size should factor into your decision: As size goes, English mastiffs need about as much room as a miniature horse. Kachalkina Veronika / Shutterstock 8 of 9 Saint Bernard Saint Bernards are big, fluffy and easy-going companions. Rita Kochmarjova / Shutterstock The Saint Bernard of brandy-toting fame is a breed originally created in the Swiss Alps and northern Italy as a rescue dog. The monks of the Saint Bernard Hospice are credited with training dogs for rescue and for playing a role in developing the breed we know today. Dogs can stand between 26-30 inches tall and weigh anywhere from 120 to 180 pounds. Though they were originally used as rescue dogs to find and save travelers, today’s Saint Bernards are mostly family dogs. They are famous for being gentle, loving, friendly, and great with children. They are also apparently great with kittens, too: Saint Bernards are known for their gentle giant nature. Rita Kochmarjova / Shutterstock 9 of 9 Leonberger A cross of three breeds created the beautiful Leonberger. Mikkel Bigandt / Shutterstock If the Leonberger reminds you of a Newfoundland mixed with a Saint Bernard, it should. That’s exactly how the breed originated. In the mid-1840s, Heinrich Essig of Leonberg, Germany, crossed a Newfoundland with a Saint Bernard for four generations, then added in a Pyrenean Mountain Dog to the mix. The result of these several generations of breeding is the Leonberger. This breed stands between 25-31 inches tall and can weigh as much as 170 pounds. But despite their size, they are simply giant family dogs. Though their main purpose is as a companion animal, the breed does very well in everything from water rescue to tracking to herding. If it is an activity that requires both strength and smarts, the Leonberger is probably going to be good at it. View Article Sources “Great Dane Dog Breed Information”. American Kennel Club.

Many of us welcomed new four-legged family members over lockdown in the last 18 months, as the Kennel Club saw dog ownership rise by nearly eight per cent to nearly 250,000 over 2020.

But if you have plenty of space and an active lifestyle you might want to consider a larger dog – which tend to make loyal and loving companions and are often more adaptable and easier to train than their more diminutive cousins. The Guinness Book of Records include a Great Dane called Zeus who stood an amazing 44 inches from the ground. Originally bred to resue people in the Alps, the Saint Bernard is big enough and strong enough to trek through deep snow for miles.

#1 – Great Dane

Also one of the tallest dogs, the Great Dane can reach 30-34 inches tall at the withers and large males can reach up to 200lbs.

#2 – Newfoundland

What looks like a large teddy bear is a dog called a Newfoundland. The heaviest recorded Newfoundland was 260lbs. and over 6 feet long! That’s quite a gentle giant!

#3 – Neapolitan Mastiff

Neapolitan Mastiffs are very large dogs in the 170-200lb. range. They, like all other mastiff breeds, are wonderful companions, if you can stand the size and the drool!

#4 – English Mastiff

Though they are one of the shorter mastiff breeds, English Mastiffs can reach up to 250 pounds. Despite their size, they are very easy keepers that require smaller amounts of exercise than most other large breeds.

#5 – Cane Corso Italiano

The Italian Mastiff is perhaps one of the most beautiful of the molossers. These dogs have a shorter weight range according to their breed standard, at about 99-110lbs. for both males and females.

#6 – Leonberger

The Leonberger looks like a lion. Coming from Leonberg, Germany, this large breed may look bigger than he really is. Although this breed has a very thick coat, he still tops the charts at 115-170lbs.

#7 – Perro de Presa Canario

The Presa Canario originates in the Canary Islands, where he was used to fight large game. Because of this, the breed weighs in around 80-130lbs.

#8 – Dogue de Bordeaux

This French Mastiff has become popular due to a canine star named Hooch. While many may want a dog with a famous cousin, they need to be prepared to house one. Dogue de Bordeaux’s are typically 120-145lbs.

#9 – Saint Bernard

These gentle giants started as excellent working dogs from the Swiss Alps. They were used as carting and rescue dogs, and therefore their size resembles that of a small horse. Males can top a weight of 264lbs!

Ginormous dogs!

Giant dogs or extra large dog breeds are large and in charge—of your heart. Despite their ginormous and intimidating size, they are teddy bears on the inside with their human families. Many giant dog breeds are in the working group, meaning they guard, protect or serve in some way. Given that mindset, they tend to be remarkably loyal and affectionate with their humans, but often aloof with strangers—at least until proper introductions are made. Giant dog breeds take up a lot of square footage at home or in the car and it can be challenging to maintain control of the leash if you need to reign them in or coax them along if they decide to do things their own way. The gorgeous and stately breeds featured below are 100 pounds or more. Keep in mind the lower weight range is for females and the higher end is males.ChristopherBernard/Getty Images

Biggest dog breed in the world: Great Dane

Great Dane’s will hog the whole sofa, but you won’t care because they are so patient, easy-going, and don’t bark much. And as far as tall dog breeds go, they’re the high-rise of canines, especially when they are on their hind legs. A Great Dane named Zeus was an astonishing 44 inches tall at the shoulder when he was named the World’s Tallest Dog by Guinness World Records in 2012. On his hind legs, he towered over 7 feet! Great Danes (which are also a brindle dog breed) have big appetites and big hearts, but those big hearts are predisposed to heart conditions.forisana/Getty Images

Mastiff

Massive and mellow with a huge helping of affection and loyalty, these big guard dogs are fiercely protective of their human family and announce “intruders” with a thunderous bark. According to the American Kennel Club (AKC), mastiffs are adept at reading human body language and expressions and can communicate with their big, soulful eyes.afhunta/Getty Images

St. Bernard

Almost anyone can identify a St. Bernard—one of the most loyal dog breeds around. It’s likely due to the popular folklore image of this mountain dog wearing a brandy cask around its neck to rescue stranded travelers on a snowy mountainside (they actually carried food and water on the packs for rescue). Fun fact: St. Bernard puppies grow big quickly. According to Animal Planet, it took around 100 St. Bernard puppies to star as the canine child inAlexanderKondakov/Getty Images

Boerboel

Also known as the “farmer’s dog,” this broad and blocky giant dog breed has roots dating back to the 1600s. Back then, the Boerboel’s intimidating size was ideal for protecting farmland and family. Yet, they aren’t hyper dogs running back and forth at the slightest provocation, rather they are remarkably calm and confident. Because Boerboels are territorial and protective of their family and love to be close to their family, they even have a soft spot for children. However, they generally don’t have much patience for dogs that challenge them, so dog parks might not be a good place to take your Boerboel.MartinFredy/Getty Images

Newfoundland

Affectionately dubbed “Newfie,” the Newfoundland is also known as a child’s beloved “nanny.” Underneath the voluminous hair that gives the breed its leonine look is a big-boned canine that is gentle and sweet-tempered yet highly protective of its family. They take the prize for best babysitter as they are exceptionally patient and fond of children. And since they’re top-notch swimmers, you’ll always have someone to take a dip with.Katerina Skokanova/Getty Images

Leonberger

Massive and majestic is the Leonberger. Bred as companions for European royalty, according to the AKC, Leonbergers commanded attention sheerly because of their immense size, holding court alongside Napoleon III, Tsar Alexander II, and King Edward VII. The Leonberger is more likely to take a dip in the lake than hold court these days. Their waterproof coat and nimbleness make them skillful swimmers, but that luxurious coat needs daily brushing, and their nails need clipping every other week. If you’re looking for a pup that will be totally devoted to your comfort, read up on the best emotional support dogs that will stand by you.SHODOgraphy/Getty Images

Anatolian shepherd

If the Anatolian shepherd had a LinkedIn profile, the skills would state “highly observant livestock protector,” “attentive family protector,” and “watchful family pet bodyguard.” Yes, even a cat. It’s one of those dogs that get along with cats. Though devoted, patient, and calm, it can be dominating and demanding, so it’s essential to start training early.Nadiia_Diachenko/Getty Images

Greater Swiss mountain dog

Right away, you can see the striking resemblance to the St. Bernard and Rotweiller, component breeds of the “Swissie.” The alert, faithful, and vigilant “Swissie” is a real sweetie. Back in the day, these mountain dog breeds pulled carts of meat and dairy to the market. Today, they are more likely to use their well-built muscles for pulling kids on carts or sleds through the snow.Anke Sauerwein/Getty Images

Irish wolfhound

If giant dog breeds had an award for the fastest-growing puppy, the Irish wolfhound, a wire-haired dog, would be a strong contender. The leggy breed’s growth is astounding, packing on nearly a pound a day until they are around six months old. As with just about any hound, hunting and chasing prey runs in their blood, so they’ll need daily exercise.Tara Gregg/Getty Images

Akita

If you’re looking for a dog with a spiritual connection, this Japanese breed is the symbol of health, happiness, and long life in its native country. New parents often receive a statute of an Akita; in fact, Japan reveres the Akita so much that they dedicated a national monument to it. An interesting fact about Akitas: they like to be clean and are virtually odorless, which is great if you plan on sharing your sofa with a huge dog breed. What’s not so great is the Akita price tag—it’s one of the most expensive biggest dog breeds in the world.Anat0ly/Getty Images

Bull mastiff

If you guessed the bull mastiff looks very similar to the mastiff and bulldog, you’re right on the money. The Bull Mastiff is 60 percent mastiff and 40 percent bulldog, so it’s no shocker it shares the same robust and powerful physique. Intimidating size aside, the Bull Mastiff is actually a lover, not a fighter. Its gentle and affectionate nature is never-ending, much like its penchant for drooling. But you’ll happily overlook that and see it as a tradeoff for Bull Mastiff’s stellar guard dog protection service it provides for the family. For even more adorable pups, check out these flat-faced dogs that are just too precious.Denys Rzhanov/Getty Images

Dogues de Bordeaux

You can call the Dogues de Bordeaux by its moniker “Mastiff of Bordeaux,” but you probably won’t find this huge dog breed nosing around in the vineyards as its head, proportionately speaking, is the largest of the dog breeds, reports the AKC. But you probably did spot a Dogues de Bordeaux if you saw the Tom Hanks movie,LourdesPhotography/Getty Images

Otterhound

When you think of the biggest dog breeds, stocky and robust physiques often come to mind, but that’s not always the case. The Otterhound is large and leggy. Widely known for their superior swimming skills, the Otterhound is the Michael Phelps of canine swimmers. It has strong shoulders and a broad chest, with webbed feet and a waterproof coat that can power through a day of swimming. Yet you would be hard-pressed to spot an Otterhound at the beach. They are one of the most endangered and rare dog breeds, according to the AKC.Jeremy Woodhouse/Getty Images

Bloodhound

Bloodhounds are low-key, mild-mannered, and lackadaisical —that is until an intriguing sight or scent piques its interest. Then all bets are off, and the stubborn, tenacious traits appear in a baying, howling, and barking medley of the Bloodhound’s greatest hits. Like some long-nosed dog breeds, this giant dog breed is scent-driven. They’re a bit slower to mature than other breeds, which may present a challenge, as Bloodhounds tend to be a bit boisterous and clumsy once they get a whiff of something irresistible. If tiny dogs are more your speed, check out these toy dog breeds that will stay puppy-sized forever.slowmotiongli/Getty Images

Kuvasz

The Kuvasz shares a striking resemblance to the Great Pyrenees—it’s nearly impossible to tell the difference between these nearly identical dog breeds. With their striking size and tons of white fluff, you wouldn’t think they would be too quick on the go, but they are actually quite nimble and agile. That’s probably due to the genes their ancestors passed down from guarding sheep. It’s vital to socialize and train the Kuvasz early on so they will be gentle with small children and other pets while they are doing their “job” of guarding and protecting them. Fun fact: this breed is also one of the best mountain dog breeds that love adventure!sssss1gmel/Getty Images

Komondor

Heads will turn when you walk down the street with a Komondor—it’s one of the adorable dog breeds that look like mops. The mop’s appearance is due to copious amounts of white corded hair meant to protect it from weather and predators when it guarded sheep. Komondor puppies have a fluffy coat that begins to mat and cord when they’re between 8 to 12 months old, says the AKC. “Koms” aren’t herding dogs but guarding dogs who are fiercely devoted and loyal to their family and his charges and will literally leap to defend them against any attack.slowmotiongli/Getty Images

Beauceron

Meet a Beauceron at the dog park, and you might think it is a mixed dog breed. Maybe a cross between a Doberman and Rotweiller? There might be a shepherd in there too. Good guesses, but the Beauceron is a French shepherd dog named for the agricultural region southwest of Paris. Beaucerons are exceptionally quick learners and, as natural safeguarders, excel in police work, rescue work, or companion dogs that offer personal protection. They’re not a breed for the beginner dog owner as they can be a dominating presence if not appropriately trained. However, when they are, they are level-headed watchdogs and guardians of all ages and abilities.Paul Biris/Getty Images

Bernese mountain dog

Though they have plenty of brains and brawn, “Berners” take their time to reach mental and physical maturity. They’re super sweet but tender-hearted and don’t respond well to harsh training. One thing you won’t have to be concerned about is excessive barking. Berners are great family dogs and super gentle and aware of a child’s small size. Given their size and luscious coat, they prefer winters over hot summers, and with all a thick, double coat, expect a lot of shedding and grooming. They’re also one of the best mountain dog breeds that love adventures!DevidDO/Getty Images

Black Russian terrier

Did we make a mistake here? Giant dog breeds can’t be terriers, right? Granted, terriers are usually small dog breeds. But as a matter of fact, the Black Russian terrier is no more than 30 percent terrier via the breed standard and is actually a working group member. “Blackies” as they are affectionately known in Russia, were initially bred to patrol Russia’s borders and hold down political prisoners. Courageous, calm, and confident, Blackies are hard-wired to guard you, not outside, alone pacing in the front yard. They are 100 percent committed to you and will literally be your black shadow all day, every day. Check out these black and white dog breeds that are just too cute to ignore.happyborder/Getty Images

Briard

There’s nothing bashful about the Briard. He loves hard and plays hard. Giant dogs don’t always require lots of exercise, but the Briard does. With its seemingly endless energy, it is fearless and confident and is the ideal outdoor adventure partner. As a loving companion, the Briard is gentle, faithful, and easily trained. They preserve much of their ancestral aptitude to guard their home and family, so they might be slow to warm up to other dogs and people, but if properly socialized, they can follow your lead and open their hearts to new friends. Don’t miss these dogs with floppy ears that are irresistibly cute.Yvonne Van der Horst/Getty Images

Rottweiler

If you haven’t been around Rottweiler’s much, you might feel that these muscle-bound guard dogs are vicious. In reality, they are immensely affectionate and gentle playmates with their own human family. Because of that, they might seem standoffish or unfriendly when you meet them, but in reality, they are just cautious. Rotties need early, extensive and continuous socialization and training to be good family members. Rotties love to do what you’re doing and if left to entertain themselves, and with their size, they are capable of creating a big mess chewing or digging.slowmotiongli/Getty Images

Estrela mountain dog

With its imposing size, loads of fur, and lovable, big round face, you see why the Estrela mountain dog could be on the list of dogs that look like bears. Hailing from the Estrela Mountains in Portugal, it is one of the oldest breeds of the region, known for its superior skills as a livestock guardian. Those strong bloodlines of guardianship hold today, but now the Estrela’s “job” is to protect their human family. Yet, the Estrela is far from being “all business.” They are exceptionally gentle and patient with young children. Their love runs deep, and like other dog breeds that live a long time, you could be sharing your life with an Estrela for many wonderful years.acceptfoto/Getty Images

Tosa

Meet the Tosa, the largest Japanese dog breed, according to the AKC. They were formerly bred for fighting, but thankfully those days are gone. These days the Tosa basks in family life. It’s no lazy slacker, though. The Tosa takes its role as the stately and vigilant guardian of the family seriously, yet, it is calm, collected, and peaceful. A properly trained and socialized Tosu is very affectionate with its family but naturally suspicious and aloof with strangers. Due to their unfortunate history of dogfighting, they might not take too kindly to another dog they meet on the street or one that visits your home. Tosa’s prefer to be your one and only pet. No cats or other small pets, please. However, if a Tosa is raised with another family dog, there’s a better chance of living peacefully.DevidDO/Getty Images

Tibetan mastiff

Are you inviting a lion or a dog to share your home with? It’s hard to tell with the Tibetan mastiff’s formidable size and mane of thick, dense fur. As a working group member, it veers on the side of being a large-and-in-charge independent thinker and guardian. It has a strong sense of self and confidently assumes it is an equal, not a pet. Yet, the Tibetan Mastiff is mellow, calm, and very affectionate with his human family and depends on their companionship to be happy and stay out of mischief. If they’re apart and alone from you for too long, they’ll find ways to entertain themselves that aren’t constructive. (Think huge dog, huge mess.)Mike Clews/Getty Images

Things to know before adopting a giant dog breed

You’ve probably already thought about if you have enough space for a huge dog breed, but there are a few more essential things you should consider before adopting a giant dog breed. For starters, they whoof down a lot of food. “A dog who weighs 100 pounds eats almost five cups a day of commercial dog kibble; then add about 1/3 cup more for every 10 pounds over 100 pounds,” says veterinarian Lyndsey Larson, VMD, ABVP, VCA Firehouse Animal Hospital in Denver. And because of their size, they’ll also require more medicine, including flea and tick preventatives. These are just two weighty factors to consider when thinking about how much it will cost to own a dog.

Giant dog breed puppy stage

Smaller dogs generally reach their full growth at around 12 months. Giant dog breeds take their time reaching their adult weight, reaching maturity between 18 to 24 months old. Behavior and training challenges are magnified when you have a huge dog, so training during the impressionable puppy stage is essential. “A good rule of thumb is to get a large breed pet into a training program and support those good habits at home between the ages of 16 weeks to one year,” advises Dr. Larson.
