11 Tiny Dog Breeds with Giant Attitudes (and 6 Giant Dogs Who Think They’re Lap Pets)

Dogs come in all shapes and sizes—but their personalities? Those can be a whole different story. Some tiny breeds puff their chests and walk like they own the block, fearless and full of fire. Others may look like they belong on a mountaintop guarding sheep, but they’re really just oversized lap dogs who want nothing more than a snuggle and a nap.

It’s this mismatch between size and spirit that makes dogs so endlessly entertaining—and endearing. One minute you’re watching a five-pound fluffball bark like it’s ready to take on a bear. The next, you’re gently coaxing a 120-pound Saint Bernard off your couch because he genuinely believes he fits there.

Whether you live in a small apartment and want a dog with big-dog energy, or you’ve got space for a gentle giant with a heart of gold, this list has something for everyone. From bold little bark machines to towering sweethearts, these 17 breeds prove that when it comes to personality, size really doesn’t matter.

Get ready to meet 11 tiny dogs with the spirit of a lion—and 6 big breeds with hearts as soft as marshmallows.

1. Chihuahua: The Tiny Titan

Standing barely 6 inches tall, Chihuahuas pack more attitude per square inch than almost any other dog. These pint-sized pooches often act like they’re ten times their actual size, fearlessly confronting much larger dogs or strangers with their signature bark.

Despite weighing only 2-6 pounds, they’re fiercely loyal and protective of their humans. Many Chihuahua owners joke that these dogs have no idea they’re small!

Fun fact: Chihuahuas are named after the Mexican state where they were discovered, and they’re one of the oldest dog breeds in the Americas, with ancestors dating back to ancient Aztec and Toltec civilizations.

2. Pomeranian: Fluffy Balls of Bravado

Pomeranians carry themselves with the dignity of royalty, all while wrapped in a luxurious coat that makes them look like adorable puffballs. These spirited little dogs typically weigh between 3-7 pounds but possess the self-assurance of a dog ten times their size.

Originally bred as sled dogs (believe it or not!), they’ve retained that working-dog determination in a much smaller package. Their alert, fox-like expression perfectly matches their bold personality.

Poms are notorious for their “big dog bark” and willingness to challenge anyone or anything they perceive as a threat, making them surprisingly effective watchdogs despite their diminutive dimensions.

3. Yorkshire Terrier: Pocket-Sized Divas

Confidence radiates from every tiny step, like a miniature supermodel on a catwalk. Their glossy, hair-like coat might scream high-maintenance, but their past tells a grittier story—once prized for catching rats in textile mills, that tenacious spark still burns bright.

At just 7 pounds, they’re known for challenging dogs much bigger, undeterred by size or status. That upright strut and always-alert expression hint at their constant readiness for action—be it a squirrel sighting or a noisy leaf.

Owners often find themselves outwitted by these sharp little characters. Behind the innocent eyes lies a streak of independence, boldness, and a bark that cuts through any silence. These dogs don’t just ask for what they want—they insist.

4. Miniature Pinscher: The ‘King of Toys’

Min Pins swagger around with such confidence that they’ve earned the nickname “King of Toys.” Often mistaken for miniature Dobermans, these independent little dogs are actually an older breed with a distinct personality all their own.

Their high-stepping “hackney gait” (similar to a horse’s trot) showcases their natural pride and elegance. Min Pins approach life with unwavering self-assurance and a touch of stubbornness that can surprise first-time owners.

Despite weighing only 8-10 pounds, these fearless little dogs will boldly announce any visitors and stand their ground against perceived threats. Their alert, curious nature makes them excellent watchdogs who take their job very seriously!

5. Shih Tzu: Royal Rebels with Attitude

Behind those adorable faces and flowing locks lies the heart of a lion – at least according to Shih Tzus! Bred as companions for Chinese royalty, these dogs haven’t forgotten their noble heritage and often expect the royal treatment.

Their name literally means “lion dog,” which perfectly captures their brave spirit despite their small 9-16 pound frame. Shih Tzus are known for their stubborn streak and tendency to train their humans rather than the other way around.

While they may look like perfect lap dogs (and they do enjoy cuddles), many Shih Tzus have a surprisingly independent streak. They’ll decide when they want attention and aren’t afraid to make their preferences known with a dignified but determined bark!

6. Papillon: Butterfly Ears, Bulldog Spirit

Named for their distinctive butterfly-shaped ears, Papillons combine delicate beauty with surprising athleticism and grit. These elegant little dogs excel in agility competitions, often outperforming much larger breeds with their speed and precision.

Weighing just 5-10 pounds, Papillons approach life with boundless energy and confidence. Their alert, intelligent expression reflects their sharp minds – they’re consistently ranked among the most intelligent toy breeds.

Don’t let their dainty appearance fool you! Papillons have a bold, adventurous spirit and will fearlessly explore new environments. Many owners report their Papillons acting as the household “supervisor,” keeping tabs on everyone’s activities with their keen, watchful eyes.

7. Toy Poodle: Small Package, Big Brains

Toy Poodles carry themselves with the dignity of aristocrats, and they have the intelligence to back up that confidence. These clever canines consistently rank among the smartest dog breeds, quickly learning new tricks and often outsmarting their owners.

Standing under 10 inches tall, these pint-sized poodles possess an athletic build under those curly coats. Many have a mischievous streak that emerges when they’re bored or understimulated.

Originally bred as water retrievers, Toy Poodles retain that working dog determination in a compact package. Their alert, attentive expression reveals their constant assessment of surroundings. Many owners describe their Toy Poodles as having “human-like” personalities with distinct preferences and opinions about everything!

8. Brussels Griffon: The Bearded Boss

With their expressive, almost human-like faces, Brussels Griffons have perfected the art of communicating their opinions – and they have many! These bearded little dogs typically weigh under 12 pounds but possess the commanding presence of a much larger breed.

Originally bred to hunt rats in Belgian stables, they retain that scrappy determination today. Their prominent chin and furrowed brow give them a perpetually serious expression that matches their no-nonsense approach to life.

Brussels Griffons form intense bonds with their humans and aren’t shy about demanding attention. Many owners report their Griffons using an impressive range of vocalizations beyond barking – from sighs and grumbles to almost speech-like sounds – to express their many thoughts and feelings.

9. Japanese Chin: Feline Attitude in Canine Form

Japanese Chins move through the world with cat-like grace and independence. These elegant little companions were bred specifically for Japanese nobility, and they haven’t forgotten their royal heritage!

Weighing just 7-11 pounds, these silky-coated dogs often display an aloof dignity with strangers while being affectionate with their chosen people. Many Japanese Chin owners note their dog’s tendency to perch on high furniture to survey their domain – just like cats.

Their distinctive flat faces with large, wide-set eyes give them an almost perpetually surprised expression that belies their calm, composed nature. Japanese Chins are known for their “Chin spin” – a unique happy dance where they spin in rapid circles when excited!

10. Havanese: Clowns with Confidence

Few dogs juggle silliness and poise quite like this one. Always eager to entertain, these fluffy charmers thrive in the spotlight—spinning in circles, bouncing on hind legs, or pulling goofy faces just to make their people laugh.

But don’t be fooled by the clownish routine. Underneath that bouncy energy lies a surprising dose of self-confidence. Whether it’s a new place or a strange sound, they meet the unfamiliar with curious eyes and a wagging tail rather than hesitation.

With roots in Cuban aristocracy, they carry a subtle elegance—when they’re not busy being adorable goofballs. Owners often joke about their dog’s “backtalk,” thanks to an endearing mix of huffs, whines, and dramatic barks that make it clear: this little showstopper always has something to say.

11. Italian Greyhound: Dainty Divas with Determination

Italian Greyhounds may look delicate with their slender legs and fine bones, but these miniature sighthounds possess surprising determination. Weighing just 7-14 pounds, these elegant speedsters can reach impressive speeds when the mood strikes them.

Behind their gentle, sometimes shy demeanor lies a stubborn streak that can catch new owners off guard. Italian Greyhounds know what they want and can be remarkably persistent in pursuing their goals, whether it’s claiming the warmest spot on the couch or convincing you it’s dinner time.

These ancient companions to nobility still carry themselves with aristocratic grace. Their large, expressive eyes seem to communicate complex thoughts, and many owners swear their IGs understand far more human language than the average dog!

Now let’s flip the script—these six big breeds may look imposing, but underneath all that size is a heart as soft as a puppy’s paw.

12. Great Dane: Gentle Giants Who Forgot Their Size

It’s hard to believe a creature this large can be so unaware of its own size. Towering over most other dogs and often weighing more than 100 pounds, these gentle giants are convinced they’re lap dogs—and won’t hesitate to prove it by climbing aboard.

For all their height and heft, they’re surprisingly soft-hearted. Skittish at times, they’ve earned a reputation as oversized scaredy-cats, known to hide behind furniture—or even their humans—when confronted with a suspicious vacuum or a wobbling chair.

The charm doesn’t end there. Their playful streak lasts well beyond the puppy years. And then there’s the signature “lean”—a loving but unbalanced move where they press their weight into someone they trust, often leaving guests wide-eyed and slightly off-center.

13. Newfoundland: Water-Loving Cuddle Monsters

Newfoundlands are legendary for their sweet temperament that completely contradicts their bear-like size. These powerful working dogs – often weighing 100-150 pounds – are natural rescuers with webbed feet and water-resistant coats perfect for water rescues.

Despite their impressive strength, “Newfies” are famously gentle, especially with children. Their patient, calm demeanor has earned them the nickname “nanny dogs.” Many Newfoundland owners share stories of their massive dogs trying to squeeze into tiny spaces or curl up on laps as if they were still puppies.

A Newfoundland’s favorite place is wherever their family is, preferably as close as physically possible. Their droopy expression often masks an intelligent, sensitive nature that makes them incredibly attuned to human emotions.

14. Bernese Mountain Dog: Floofy Snuggle Bears

Built for work in the snowy Swiss Alps, these sturdy canines once hauled carts and herded cattle—but nowadays, they’re more focused on sneaking onto sofas and snuggling their humans. Despite tipping the scales at up to 115 pounds, they seem to believe they’re still lap-sized pups.

With a luxurious tri-colored coat and a face that always looks like it’s mid-smile, they radiate good-natured charm. One of their signature moves? The “lean-in hug”—a gentle press against your side that says, “You’re my favorite,” often paired with a soft, blissful gaze.

Personal space? Never heard of it. These lovable giants have a knack for sprawling across laps, wedging themselves into tight spots on the couch, or flopping on top of you without a second thought.

15. Irish Wolfhound: Tall, Lanky Lap Seekers

Irish Wolfhounds hold the distinction of being the tallest dog breed, with males often standing over 30 inches at the shoulder. These ancient hunting dogs were once fierce enough to hunt wolves, but modern Wolfhounds are known for their exceptionally gentle, laid-back temperament.

Their imposing size (often 100-120 pounds) contrasts sharply with their sensitive souls. Many Irish Wolfhound owners describe their dogs as “gentle giants” who are surprisingly graceful despite their enormous frames.

What truly sets Wolfhounds apart is their touching desire for closeness with their humans. They’ll often attempt to be lap dogs, resulting in comical situations as they try to arrange their long, gangly limbs to fit on furniture or laps that are comically undersized for their massive frames!

16. Leonberger: Mountain-Sized Mushballs

With the look of a lion but the heart of a teddy bear, these colossal canines (weighing anywhere from 90 to 170 pounds) strike a regal pose—right before flopping over like oversized puppies in need of a belly rub.

Bred more for companionship than labor, they shine in their role as gentle, loyal family members. Calm and patient by nature, they’re particularly good with children, though their sheer size means a little caution goes a long way.

Owners often laugh at their dog’s comic contradictions—like squeezing under coffee tables during thunderstorms or insisting on climbing into laps during quiet evenings. Behind those dramatic eyebrows and deep, soulful eyes is a tender spirit that melts hearts as easily as it topples furniture.

17. Saint Bernard: Drooling Giants with Tender Hearts

Saint Bernards may be famous for alpine rescues with brandy barrels, but today’s Saints are more likely to “rescue” your personal space! These enormous dogs – often weighing 120-180 pounds – combine impressive strength with surprising gentleness.

Their wrinkled brows and soulful eyes give them a perpetually worried expression that matches their protective nature. Despite their intimidating size, Saint Bernards are typically calm, patient dogs who move through life with a deliberate, unhurried pace.

The Saint Bernard’s most endearing quality might be their complete lack of awareness about their size. Many owners share stories of their massive dogs attempting to curl up in tiny dog beds or sit on laps, creating comical situations as these gentle giants try to fit into spaces clearly designed for much smaller pets!
