Ever been startled by a big, scary-looking dog only to find yourself receiving slobbery kisses moments later? Appearances can be deceiving in the canine world!
Some of the most intimidating breeds are actually big softies at heart, while certain cute pups pack an unexpected punch of attitude.
Whether you’re looking for a gentle giant or want to know which adorable dogs might have a spicy personality, this guide reveals the truth behind canine appearances.
1. Rottweilers: The Misunderstood Teddy Bears

Behind those powerful jaws and muscular build lies a deeply loyal companion who’s remarkably patient with children. Rotties often think they’re lap dogs despite weighing up to 135 pounds! Their intimidating appearance has given them an unfair reputation.
Properly trained Rottweilers display incredible gentleness. They’re thoughtful, intelligent dogs who assess situations before acting – not the impulsive biters some fear. Most Rottie owners describe their pets as goofy, loving family members.
These protective pups form strong bonds with their families and show surprising sensitivity to human emotions. They’re known to offer comfort during tough times with a gentle paw or a lean against your leg.
2. American Pit Bull Terriers: Wigglebutts With Heart

Once America’s nanny dogs, Pit Bulls were trusted babysitters for children before their reputation was tarnished. Their wide smiles and enthusiastic tail wags (that famous ‘pittie wiggle’) reveal their true joyful nature. These dogs live to please their humans.
Pit Bulls consistently score better on temperament tests than many ‘family-friendly’ breeds. They’re incredibly affectionate, often trying to be lap dogs despite their solid muscle build. Their eagerness for human approval makes them highly trainable.
The American Temperament Test Society found that American Pit Bull Terriers pass temperament tests at a higher rate (87.4%) than Golden Retrievers. These misunderstood dogs typically shower strangers with kisses rather than aggression.
3. Doberman Pinschers: Velcro Dogs In Disguise

Dobermans might look like they belong in security roles (and they excel there!), but owners know them as ‘velcro dogs’ who can’t bear to be separated from their humans. These sleek, athletic dogs were bred to be personal protectors, not aggressive attackers.
Modern Dobermans have been carefully bred to balance protective instincts with a gentle disposition. They’re incredibly sensitive to their owner’s emotions and often respond with touching empathy. Many Dobie owners report their dogs checking on family members who are crying or upset.
Despite their stern appearance, they’re playful goofballs at home. A Doberman will do anything for a laugh, including elaborate play-bows and silly antics that completely contradict their dignified public image.
4. Boxers: The Eternal Clowns

Don’t let those muscular bodies and alert expressions fool you – Boxers are the comedians of the dog world! With their bouncy energy and expressive faces, they’ll have you laughing daily. Their reputation as fighting dogs is ancient history.
Boxers are known for their patience with children. They seem to understand their own strength and adjust their play style accordingly. Many families consider them the perfect playmates for active kids.
These goofballs are masters of the ‘kidney bean’ – a curved position where they wiggle their entire bodies with joy upon seeing their favorite humans. Despite their athletic build and squared jaw, Boxers are sensitive souls who form deep emotional connections and hate being separated from their families.
5. Great Danes: Gentle Giants Who Think They’re Tiny

Standing nearly three feet tall at the shoulder, Great Danes make an intimidating first impression. Yet these giants are famously called ‘the Apollo of dogs’ for their combination of strength and sweetness. Most Dane owners report their massive dogs are afraid of the smallest things – from vacuum cleaners to tiny puppies!
Despite their imposing size, they’re incredibly gentle with children and smaller pets. Great Danes are known for carefully navigating spaces as if they’re aware of their size (though they’ll still try to sit in your lap).
These dogs were bred to hunt boars but evolved into aristocratic companions. Today’s Great Danes are lover dogs who would rather cuddle than chase – though they might accidentally knock things over with their happy tail!
6. Staffordshire Bull Terriers: Nanny Dogs With Smiles

Staffies have such powerful jaws and muscular bodies that they’re often mistaken for fighting dogs. The truth? They were nicknamed ‘nanny dogs’ in England for their exceptional patience with children. Their smiling faces and wiggly bodies reveal their true sweet nature.
The American Kennel Club describes them as ‘brave, tenacious, and clever’ but also notes they’re ‘extremely loving.’ Staffies typically greet everyone as potential best friends. They’re known for their distinctive ‘Staffie smile’ that makes them look like they’re grinning from ear to ear.
These stocky pups are surprisingly sensitive. They form intense bonds with their families and can actually develop depression if left alone too much. Despite their tough appearance, they’re emotional velcro dogs who just want to be part of the family action.
7. Cane Corsos: Renaissance Softies

With ancient Roman lineage and a name that translates to ‘bodyguard dog,’ Cane Corsos look like they walked straight out of a gladiator arena. Their massive heads and muscular bodies can make strangers cross the street! Yet properly raised Corsos are incredibly balanced and calm.
These Italian mastiffs form unbreakable bonds with their families. They’re especially protective of children, whom they view as precious members of their pack. Around their trusted humans, they show a surprisingly tender side.
Cane Corsos are remarkably intuitive – they can read a room better than most humans. They know exactly when to be playful and when to be calm. Despite their intimidating appearance, well-trained Corsos are gentle souls who would rather nap beside you than cause trouble.
8. Bullmastiffs: Gentle Giants With A Soft Spot

Originally bred to catch poachers in English game reserves, Bullmastiffs can weigh up to 130 pounds of pure muscle. Their intimidating size and serious expression hide their true nature – they’re actually sensitive souls who hate confrontation!
Unlike many guard dogs, Bullmastiffs were trained to track and hold poachers without harming them. This non-aggressive approach remains in their DNA. They prefer to block intruders with their body rather than attack.
Around family, these giants transform into oversized teddy bears. They’re famously good with children, showing remarkable patience and gentleness. Many Bullmastiff owners report their dogs seeking out the smallest family member to protect, following toddlers around with touching devotion.
9. German Shepherds: Working Dogs With Teddy Bear Hearts

German Shepherds’ wolf-like appearance and use in police and military roles have given them a reputation for aggression. In reality, they’re incredibly sensitive dogs who form deep emotional bonds with their families. Their fierce loyalty is often misinterpreted as aggression.
These intelligent dogs are famous for their problem-solving abilities. They can learn over 100 words and follow complex commands. This intelligence comes with emotional depth – they’re known to comfort family members who are upset.
Well-socialized German Shepherds are remarkably gentle with children and smaller animals. They seem to understand their strength and adjust accordingly. Far from being naturally aggressive, they’re actually quite reserved with strangers until they determine there’s no threat to their loved ones.
10. American Bullies: Muscle-Bound Cuddle Machines

American Bullies might look like canine bodybuilders with their broad chests and muscular builds, but they’re actually bred specifically for companionship rather than aggression. Their intimidating appearance couldn’t be further from their true personality – they’re basically living teddy bears!
Unlike their fighting ancestors, modern American Bullies have had aggressive tendencies deliberately bred out. They’re known for their stable temperaments and extraordinary patience. Many bully owners describe their dogs as ‘couch potatoes’ who live for snuggle time.
These stocky pups typically love everyone they meet – from children to other pets. They’re so people-oriented that they often suffer from separation anxiety when apart from their humans. Despite looking tough, they’re sensitive souls who just want to be loved.
11. Chihuahuas: Tiny Terrors With Big Attitudes

Don’t let those big doe eyes and tiny bodies fool you! Chihuahuas often pack more attitude per pound than any other breed. These pint-sized pups have earned their reputation as ‘small dog syndrome’ champions for good reason.
Many Chihuahua owners report their tiny companions act like they’re ten times their actual size. They’ll fearlessly stand up to dogs twenty times larger! This boldness stems from their history as revered companions in ancient civilizations – they’ve never forgotten their royal roots.
Behind that feisty exterior lies a fiercely loyal heart. Chihuahuas bond intensely with one person and will defend them with surprising courage. They’re also surprisingly sturdy despite their delicate appearance, with many living well into their late teens.
12. Pomeranians: Fluffy Dictators With Royal Attitudes

These cotton-ball fluffballs descended from large Arctic working dogs, and they haven’t forgotten their powerful ancestry! Behind that adorable fox-like face and pom-pom body lurks the heart of a much bigger dog. Pomeranians often act like they’re running the household – and usually succeed!
Queen Victoria’s love for Pomeranians helped popularize the breed, and these little dogs seem aware of their royal connections. They’re known for their bossy barking and tendency to ‘patrol’ their territory with surprising authority.
Despite weighing just 3-7 pounds, Poms have been known to chase off much larger animals they perceive as threats. They’re fearless protectors who seem genuinely unaware of their tiny size. Many Pomeranian owners joke that their dogs suffer from ‘delusions of grandeur.’
13. Dachshunds: Sausage-Shaped Hunters With Attitude

Those adorable elongated bodies and floppy ears hide the soul of a tenacious hunter! Bred to battle badgers underground (their name literally means ‘badger dog’ in German), Dachshunds maintain a surprisingly fierce streak beneath their comical appearance.
Their stubborn determination can manifest as bossiness at home. Many Dachshund owners report their little hotdogs attempting to rule the household with an iron paw. They’re notorious for their selective hearing when it comes to commands they don’t fancy following.
Dachshunds consistently rank high in studies of dog aggression, particularly toward strangers and other dogs. This isn’t random – it’s their hunting heritage showing through. That said, they form deeply devoted bonds with their families, often becoming extremely protective of their chosen humans.
14. Shih Tzus: Royal Divas With Secret Sass

Don’t be fooled by those flowing locks and sweet faces! Shih Tzus were bred as companions to Chinese royalty, and they’ve never quite forgotten their imperial origins. Behind those adorable button eyes often lurks a stubborn streak a mile wide.
Their name translates to ‘little lion,’ which hints at their surprisingly bold personality. Many Shih Tzu owners discover their fluffy friends have definite opinions about how things should be done. They’re masters of the judgmental stare when displeased!
These little lions can be remarkably territorial for such small dogs. They’ll fearlessly announce visitors with surprisingly deep barks that seem impossible from such tiny bodies. While generally loving, they can be quite selective about who receives their royal affection.
15. Lhasa Apsos: Fluffy Sentinels With Ancient Attitudes

Those flowing coats and sweet faces hide one of the oldest and most independent dog breeds in existence! Lhasa Apsos served as interior sentinels in Tibetan monasteries for over 2,000 years, and they take their security duties seriously even today.
Don’t be deceived by their size – these dogs were never bred to be cuddly lapdogs. They’re suspicious of strangers by nature and can be surprisingly territorial. Many Lhasa owners describe their pets as ‘aloof’ or ‘cat-like’ in their independent nature.
Their fierce loyalty to family contrasts sharply with their wary approach to outsiders. While they form deep bonds with their chosen people, they maintain a dignified reserve that can surprise those expecting a typical small companion dog. These ancient guardians haven’t forgotten their noble heritage!
