Small dogs often get mistaken for being fragile or yappy, but don’t let the size fool you—many of these pint-sized pups are packed with personality, brains, and confidence. If you’re looking for a dog that won’t break your back (or your apartment lease), breeds under 40 pounds are the sweet spot.
They’re easy to carry, easier to travel with, and ideal for small homes, city living, or just those who don’t want 80 pounds of dog in their lap. But small doesn’t mean boring—these breeds run the gamut from playful clowns to couch-loving cuddlers, each bringing their own flavor of fun.
Whether you’re seeking a portable pal, an energetic walking buddy, or a mellow companion with low maintenance needs, there’s a little dog out there for you. And don’t worry—they might be compact, but their loyalty is extra large.
Let’s dive into the world of under-40-pounders who prove that good things really do come in small, wagging packages.
Dog Breeds Under 40 Pounds
1. Pomeranian
When it comes to dog breeds under 40 pounds, the Pomeranian is basically the tiny tornado of the canine world.
Don’t let their size fool you — these little fluff balls pack an outsized personality that’s equal parts diva, comedian, and loyal best friend. At around 3 to 7 pounds, they fit perfectly in your lap, your bag, or maybe even your coffee mug (okay, maybe not that small, but you get the idea).
✅ Their double coat is like wearing a never-ending cloud of cotton candy. You’ll find yourself running your fingers through their fur more often than checking your phone — guaranteed.
✅ They’re known for their loud “alarm system” bark. Expect your Pomeranian to alert you if a leaf blows by outside, or if the mailman so much as breathes near the door.
✅ Despite being pint-sized, Poms are confident, courageous, and love to be the center of attention — basically the little royalty of the dog park.
✅ Thanks to their size, these cuties make excellent travel companions. Road trip? Check. Airplane-friendly? You bet. Couch snuggler? Absolutely.
Bonus Humor: If you’ve ever met a Pomeranian, you know they believe their mission in life is to convince everyone they’re actually a fierce tiger trapped in a teddy bear’s body. Spoiler alert: They’re right.
2. Yorkshire Terrier
Step aside, fashionistas — the Yorkshire Terrier (or “Yorkie,” if you want to sound like you know the in-crowd) is here to strut their stuff.
Weighing in at a dainty 4 to 7 pounds, this little diva is basically the runway model of small dog breeds. With silky, flowing locks that could give supermodels a run for their money, Yorkies bring style, sass, and a sprinkle of spunk wherever they go.
✅ Their shiny coat isn’t just for show — it’s a lifestyle. Expect regular pampering sessions, because this pup takes grooming seriously (and you’ll want to too).
✅ Don’t let the petite frame fool you — Yorkies think they’re ten feet tall. They’re fearless, feisty, and will guard your heart (and your snacks) with fierce loyalty.
✅ They’re people lovers through and through, loving attention and cuddles. But also prepared to be the boss of your house with just a tiny growl.
✅ Super smart and quick learners, Yorkies can easily pick up tricks and commands — as long as they feel like it, of course.
Bonus Humor: If there was a competition for “Big Dog Energy in a Small Body,” Yorkies would win gold every time — and then demand a royal treat for their efforts.
3. Havanese
Meet the Havanese — the charming little charmer from Cuba who’s basically a walking, wagging bundle of sunshine and fluff.
Weighing in between 7 to 13 pounds, this breed is perfect if you want a small dog who doubles as your personal happiness machine. Plus, their silky, sometimes curly coat gives you endless reasons to brush and admire (you might even start talking to it).
✅ These pups have a sunny personality that’s contagious. Bad day? One look into those big, sparkling eyes and your troubles melt away.
✅ Havanese thrive on love and attention — they’ll happily follow you around like a tiny, fluffy shadow who’s basically your #1 fan.

✅ Whether you live in a cozy apartment or a spacious home, the Havanese adjusts like a pro — plus, their size means they’re travel-friendly pals for your adventures.
Bonus Humor: If happiness had a dog-shaped mascot, it would be the Havanese — mostly because they’re too cute to say no to when they beg for snacks… with those big “puppy-dog” eyes. Resistance is futile.
4. Shih Tzu
If you want a pint-sized pooch who thinks they’re pure royalty, look no further than the Shih Tzu. Weighing between 9 and 16 pounds, this breed is basically a fluffy emperor wrapped in a little bundle of mischief.

As per WebMD, Shih Tzus don’t require much space, making them perfect pets for owners living in homes or apartments of any size.
Bonus Humor: Shih Tzus have perfected the art of “I’m cute, so you have to do what I want” — and honestly, who could say no to that face?
5. Papillon
Don’t let the fancy name fool you — the Papillon is basically the tiny acrobat of the dog world. Weighing just 5 to 10 pounds, these little dogs are instantly recognizable by their iconic butterfly-like ears that give them a look that’s equal parts elegant and mischievous.
Papillons remain beloved family dogs and loyal companions today. They’re cheerful, friendly pups who thrive on spending quality time with their humans. Beyond being great pets, Papillons often shine in agility competitions and can also serve as therapy and service dogs, PetMD noted.
✅ Those huge, fringed ears aren’t just for show — they’re also excellent at catching every secret whisper or snack bag rustle in the room.
✅ Papillons are tiny bundles of energy who love to jump, run, and play — they’re practically the Olympic gymnasts of small dogs.

✅ Beneath that sprightly exterior is a loyal companion who bonds deeply with their family and always wants to be part of the action.

6. Italian Greyhound
If sleek and chic had a canine form, it would be the Italian Greyhound — the supermodel of the small dog world.
Weighing between 7 to 14 pounds, these pups look like they just stepped off a runway, sporting a slender, graceful body that’s all about speed and style. But don’t let their delicate appearance fool you — inside beats the heart of a sprinter ready for zoomies at any moment!
✅ These pups are sprinters with turbo-charged zoomies, so a backyard or park where they can run free is their happy place.
✅ Their short, smooth coat feels like the softest velvet — perfect for snuggling during those chill downtime moments.
✅ Italian Greyhounds can be a bit shy or sensitive, so they thrive in calm, loving homes where they feel safe and adored.
✅ After burning off their energy, they become cuddly little lap heaters who love nothing more than to burrow under a blanket.

7. Beagle
Say hello to the Beagle — the four-legged detective with a nose that never quits and a personality that’s pure sunshine. These dogs feature a smooth, dense double coat, a tail that seems to wag nonstop, and charming floppy ears.
Weighing in around 20 to 30 pounds, Beagles are sturdy little adventurers who are happiest when on the move, nose to the ground, hunting down new scents like it’s the ultimate treasure hunt.
✅ Their incredible sense of smell means they’re always on a mission — whether it’s tracking a trail in the park or finding the hidden treats you definitely dropped.
✅ Beagles are affectionate, playful, and great with kids, making them a perfect family dog with endless energy to burn.

Bonus Humor: Be prepared for the Beagle’s signature “stubborn sniff and ignore” move when you call them — their nose usually wins the battle.
8. Basenji
Meet the Basenji — the “barkless dog” who’s basically the ninja of the small dog world.
Weighing between 20 to 24 pounds, this sleek, elegant pup doesn’t do the usual woof-woof. Instead, they communicate with a quirky mix of yodels, howls, and chortles that’ll leave you both confused and amused (and wondering if your dog just discovered a secret language).
✅ No bark? No problem! They’re alert, smart, and communicate in their own mysterious way — perfect if you want a dog who’s not a noisy neighborhood alarm system.
✅ Basenjis groom themselves like tiny cats, keeping their coats sleek and shiny without much help (bonus points for low maintenance!), says Purina.
✅ These dogs are fast, agile, and love a good challenge. They’ll happily sprint, jump, and explore with the energy of a pup twice their size.
✅ Basenjis have a mind of their own — which means training requires patience, creativity, and a good sense of humor.
Bonus Humor: If Basenjis had a motto, it would probably be: “I’m not ignoring you, I’m just… thinking really hard.” (Translation: They’re just being adorably stubborn.)
9. Cocker Spaniel

Bonus Humor: Warning: With all that charm and those soulful eyes, you might find yourself powerless to resist their “please, just one more treat” stare. Resistance is futile.
Conclusion
Dog breeds under 40 pounds are considered as small to medium-sized dog breeds. They are a perfect addition for active households and pet owners seeking wonderful family companions that form strong bonds with children, strangers, and other animals alike. While there are many medium-sized herding breeds like the Australian Cattle Dog, Australian Shepherd, and German Shorthaired Pointer. Other medium-sized breeds like Portuguese Water Dog, American Staffordshire Terrier, Basset Hounds, English Springer Spaniel also fall in this category.
However, smaller breeds such as the Soft Coated Wheaten Terrier, Kerry Blue Terrier, and Bearded Collie offer an affectionate nature with manageable coat types and regular grooming needs. These highly intelligent breeds, originally bred for work or herding, are well suited to families looking for active breeds that balance playfulness with loyalty. Whether it’s the tri-color Standard Poodle or the spirited Shetland Sheepdog, these smaller dogs deliver personality, protection, and companionship without the bulk of larger dogs like the Golden Retriever or Siberian Husky, making them some of the most popular dogs for city living or homes with limited space.
