10 Large Dog Breeds That Make Terrible Guard Dogs (Who Might Invite Strangers in For Hugs)

Not all big dogs are cut out for the tough job of guarding your home—some would rather welcome intruders with a wagging tail and a few slobbery kisses! Breeds like the lovable Labrador or the gentle Great Dane are known for their friendly and social nature, making them more likely to invite a stranger in for a cuddle than to stand guard. These dogs are much more about making friends than protecting their territory. While they may not be ideal for guarding, they’re perfect for families looking for a large, affectionate companion who’s all about love, not fear.

Golden Retriever: The Ultimate People-Pleaser

Golden Retrievers are known for their stunning golden coats and heart-melting eyes, but their personalities are even more beautiful. These dogs adore everyone they meet, whether it’s family, friends, or the mail carrier. If a stranger walks through your door, a Golden Retriever is more likely to greet them with a toy in their mouth than a growl. Their gentle nature and eagerness to please make them one of the least intimidating breeds around. In fact, they’ve been known to bring comfort to hospital patients and help children learn to read, proving that their hearts are as big as their bodies. While their size might suggest a formidable presence, their wagging tail gives away their true intentions. For Golden Retrievers, every day is a chance to make a new friend, not to guard the castle.

Newfoundland: The Sweet-Natured Giant

Often described as “nanny dogs,” Newfoundlands are so gentle and loving that they’ve earned a reputation for being fantastic with children. These dogs are massive, often weighing over 150 pounds, but their hearts are even bigger. When faced with a stranger, a Newfoundland’s first instinct is to offer a friendly nuzzle or a slobbery kiss. Their calm demeanor and patient nature make them terrible guard dogs, as they rarely bark or show any signs of aggression. Instead, they’ll likely welcome visitors with open paws and a wagging tail. It’s no wonder they’re called gentle giants—these dogs are all about love, not protection. Anyone expecting a fierce protector will be sorely disappointed, but those seeking a cuddle buddy will find a dream come true.

Bernese Mountain Dog: Friendly by Nature

Bernese Mountain Dogs look like they could ward off a bear, but in reality, they’d probably invite one over for a playdate. Renowned for their affectionate and gentle temperaments, these Swiss beauties are known as family dogs through and through. They thrive on human interaction and are quick to trust anyone who enters their home. If a stranger arrives, a Bernese Mountain Dog is more likely to wag their tail in excitement and lean in for a pet than raise the alarm. Their good-natured personalities make them wonderful companions but utterly hopeless as guard dogs. The only thing they’re likely to protect is their spot on the couch—or maybe their favorite chew toy.

Irish Wolfhound: The Gentle Giant of Legends

Standing as one of the tallest dog breeds in the world, Irish Wolfhounds might look intimidating at first glance. But don’t let their size fool you—their personalities are as soft as a cloud. Known for their calm and patient nature, these dogs are more likely to befriend a stranger than scare them off. In fact, Irish Wolfhounds are often described as gentle, dignified, and even a bit shy. If someone enters your home, this giant might quietly observe or offer a friendly sniff, rather than bark or act defensively. Their laid-back attitude and lack of suspicion towards strangers make them a poor choice for guarding anything except your heart.

Saint Bernard: The Lovable Lifesaver

Saint Bernards are famous for their heroic mountain rescues, but when it comes to protecting your home, they’d rather offer a warm welcome. These dogs have an enormous presence, but their personalities are all about love and affection. Saint Bernards are gentle, patient, and famously friendly, even towards people they’ve never met. Their tendency to drool on guests and seek out hugs makes them more of a host than a sentry. A Saint Bernard’s idea of “guarding” is making sure every visitor feels comfortable and well-loved. If you’re looking for a dog to deter intruders, this breed might just invite them in for a cup of hot cocoa.

Great Dane: The Friendly Giant

Great Danes are often called the “Apollo of dogs”—majestic, tall, and awe-inspiring. But behind that regal appearance is a goofy, friendly soul who just wants to be everyone’s best friend. These dogs are notorious for their gentle nature and their love of human companionship. If a stranger comes knocking, a Great Dane might bark out of excitement, but it’s usually followed by a clumsy attempt to sit in their lap. Their affectionate personalities make them wonderful family pets, but their lack of suspicion and eagerness to socialize render them ineffective as guard dogs. In the world of canine guardians, Great Danes are more about love than law enforcement.

Leonberger: Gentle and Sociable

With their lion-like manes and sturdy frames, Leonbergers might look like they belong in a fairy tale castle. However, these dogs are gentle, friendly, and exceptionally sociable. Leonbergers love being around people and are incredibly tolerant, making them great therapy and family dogs. They rarely show aggression, even to strangers, and their calm, steady demeanor means they’re more likely to wag their tail than bark at an unfamiliar face. While their sheer size may give pause to some, Leonbergers are far more interested in making friends than defending territory. Expect them to greet newcomers with a friendly sniff and a hopeful look for a treat.

Old English Sheepdog: The Fluffy Friend-Maker

Nothing says “cuddle me” quite like an Old English Sheepdog. With their shaggy coats and endearing personalities, these dogs are the definition of friendly. They’re known for their playful attitude and love of human interaction. Old English Sheepdogs are not suspicious by nature, and if a stranger enters their home, these dogs are more likely to invite them to join in a game of fetch than sound the alarm. Their easygoing nature and tendency to welcome everyone make them terrible guard dogs but fantastic companions. Anyone looking for a dog to protect their home should know that this breed’s idea of defense is a joyful wag and a bouncy greeting.

Greater Swiss Mountain Dog: Trusting and Cheerful

Greater Swiss Mountain Dogs are big, strong, and incredibly trusting. Their cheerful disposition makes them a hit with families and strangers alike. Rather than barking at or confronting newcomers, these dogs are more likely to greet them with enthusiasm and curiosity. Their trusting nature means they’re quick to befriend anyone who enters their space, making them unreliable as guard dogs. While their size can be imposing, their hearts are gentle, and their reactions to strangers are usually friendly and welcoming. If you’re seeking a loyal friend rather than a fierce protector, the Greater Swiss Mountain Dog is a perfect choice.

Borzoi: The Reserved, Elegant Companion

Borzoi dogs, with their elegant appearance and long, graceful bodies, might look aloof, but they are anything but aggressive. Known for their gentle and reserved nature, Borzois are often shy around strangers rather than defensive. Instead of barking or growling, they usually keep their distance or approach with quiet curiosity. These dogs are much more likely to watch a stranger with mild interest than try to protect their home. Their calm demeanor and lack of territorial instinct make them terrible guard dogs, but wonderful, gentle companions for those who appreciate a quieter, more relaxed canine friend.

In the end, while these large breeds might not make the best guard dogs, they excel in providing love, companionship, and endless affection. Their friendly nature means they’ll treat every stranger like a new best friend rather than a threat. If you’re after a gentle giant who loves everyone, these breeds are perfect for cuddles and playtime, not standing watch. With the right training and environment, they’ll always have your back in their own, very loving way!
