Most people know that small dogs tend to outlive large ones, but the actual numbers can still catch people off guard. Dogs that live the longest, which are mostly small breeds, can often reach their late teens or even early twenties, while extra-large breeds like Great Danes and Newfoundlands typically only live about seven to ten years. That’s a striking gap when you think about what it means in real terms of companionship.
Research has shown that small dogs typically live longer than large breeds, as the latter are more prone to joint and bone problems, stomach troubles, and hormone disorders, among other issues. Large dog breeds also have higher rates of heart disease, arthritis, and cancer as they get older. So if you’re weighing your options, it’s worth knowing which small breeds consistently punch above their weight when it comes to longevity. These are 21 of them.
#1. Chihuahua

Weighing only two to six pounds, Chihuahuas are one of the smallest and longest-living dog breeds around. They’re known for their long lifespan, with some living up to 20 years. That’s a remarkable run for any dog, and it’s backed up by documented records. One of the longest-lived dogs on record was a Chihuahua that lived for 20 years and 265 days.
Congestive heart failure is the leading cause of death in older Chihuahuas, so keeping senior pups up to date on their wellness visits to the vet is important. Otherwise, they aren’t prone to many serious health issues and are a great choice for those looking for a long-living companion. Dental care matters enormously for this breed too, given their small mouths and tendency toward overcrowding.
#2. Toy Poodle

As the smallest of the three Poodle sizes, Toy Poodles weigh between four and six pounds and can live up to 18 years. Their intelligence is equally impressive. Though small, Toy Poodles have a big personality and an even bigger brain, and they are so smart that basic training and complicated tricks can be taught relatively easily.
Despite their extra-long lifespan, Toy Poodles can experience common small-dog health issues like eye issues, dental disease, Legg-Calvé-Perthes disease, and luxating patellas. Routine veterinary care and attentive grooming go a long way with this breed. Their curly coats require regular maintenance, but the payoff is decades of devoted, lively companionship.
#3. Maltese

These white and curly-haired dogs get their name from their heritage in Malta. While they generally live for around 15 years, the oldest Maltese dog to have ever lived was 20 years old. That kind of ceiling makes them one of the more inspiring breeds on this list.
The Maltese breed exhibits both elegance and remarkable courage while showing a gentle nature. According to Purina, this breed typically has a life expectancy of 12 to 15 years. The small dogs serve as effective watchdogs because they maintain high alertness while showing deep loyalty to their owners. Their white coat needs daily attention, and dental health is something owners should keep a close eye on throughout the dog’s life.
#4. Yorkshire Terrier

Yorkies are tiny dogs with big personalities. They typically live 13 to 16 years. Despite their size, they have a strong immune system and relatively few genetic health problems. It’s a combination that serves them well into old age.
The Yorkshire Terrier is a dog with a long lifespan and a long coat to match. Their hair needs daily care to stay free of matting and tangles, or you can keep it trimmed short to make brushing easier. They’re spirited and social, which means they thrive best in homes where they get consistent attention and activity rather than being left to their own devices.
#5. Dachshund

The Dachshund is a small dog breed known for its short legs and long body. With a lifespan of 12 to 20 years, the Dachshund is a popular breed among dog owners who want a loyal, long-lived companion. That upper range of 20 years is remarkable by any measure.
Due to their long backs, these dogs should not live where they will have to do a lot of stair climbing. Spinal health is one area to watch carefully. With a body built the way theirs is, intervertebral disc disease is a real concern, and keeping their weight in a healthy range is one of the most effective ways to protect their backs across their long lives.
#6. Pomeranian

Pomeranians, often nicknamed poms or pom poms, are not only the life of the party anywhere you go, but they’ll be partying with you, on average, for 14 to 16 years. Some individuals have been known to push well beyond that, with reports of Pomeranians living as long as 20 years.
Pomeranians are actually descended from sled dogs, and their predecessors weighed around 30 pounds. Once they captivated Queen Victoria and became more popular, Poms were selectively bred to be the tiny, cute dogs we know today. That rich history is part of what makes them such a surprisingly hardy little breed. Their fluffy double coat needs regular brushing to stay tangle-free.
#7. Shih Tzu

Shih Tzu has a very long lifespan, living from 10 to 16 years. The broad range reflects how much care and breeding quality can influence the actual outcome. Small but mighty, the Shih Tzu was bred by Buddhist monks in Tibet to look like a little lion. These tiny, cute dogs are very attached to their pet parents and their long and luxurious coats need lots of attention to stay tangle-free.
Shih Tzu were bred to be companions, so they make excellent lapdogs and are happy to live a pampered lifestyle. However, they still need to keep their paws moving so they stay at a healthy weight and don’t become bored. Their flat faces can create some breathing challenges, which is worth discussing with a vet when planning for their senior years.
#8. Papillon

The Papillon has an average lifespan of 13 to 16 years, with an average of 14.5 years. Papillons are small dogs with a long lifespan and big ears with gorgeous feathering. Despite their delicate appearance, they’re athletic and excel in dog sports like agility. These friendly dogs love being around people, and they need lots of mental stimulation to stay happy and healthy.
Elegant and stylish, Papillons are named after their wispy ears that resemble butterfly wings, as papillon means butterfly in French. This small dog is also highly intelligent and needs ample activity and mental stimulation to ward off boredom. Some of the Papillon’s favorite pastimes are taking long walks, running an agility course, and playing with their favorite people.
#9. Coton de Tulear

While it’s hard to say what dog breed lives the longest of all, because several factors beyond breed play a role in longevity, the Coton de Tulear has a reputation for its extended lifespan. According to the American Kennel Club, the small breed can live upwards of 19 years. That’s a genuinely impressive ceiling for any dog.
The adaptable Coton de Tulear fits well into many lifestyles, from busy families to retirees. Though the breed’s exercise needs are modest, their white coat needs to be brushed every day to prevent matting and tangles. If you don’t mind sticking with this routine for nearly two decades, Cotons make great companions.
#10. Jack Russell Terrier

The sparky and energetic Jack Russell Terrier happens to be one breed that is rarely associated with severe health risks, a factor that increases the life expectancy of these little dogs. Jack Russells are happy to live alongside you for up to 14 to 15 years. Their health robustness is a genuine standout quality.
Commonly called Jack Russells, Parson Russell Terriers are best suited for experienced and very active pet parents. They are little balls of energy who almost always want to be on the go and engaged in whatever you’re doing. Because of their background as vermin hunters, Parson Russell Terriers have a strong prey drive, so all their exercise should be done on a leash or in a securely fenced area.
#11. Miniature Pinscher

Miniature Pinschers usually live 12 to 16 years. Nicknamed the “King of Toys,” the Miniature Pinscher has a distinctive “hackney” gait, a high-stepping prance reminiscent of a trotting Hackney horse. They are instantly recognizable and carry themselves with a confidence that seems entirely at odds with their compact frame.
Breeders developed the Miniature Pinscher in Germany to hunt rats in stables. The breed is not a miniature version of the Doberman Pinscher, as commonly thought. In fact, the Miniature Pinscher is much older than the Doberman, though the two breeds share some common ancestors. They’re bold, alert, and deeply loyal to their families.
#12. Havanese

Havanese are another small breed. They’re very fluffy with long, silky hair. Many people find they make fairly cuddly dogs, which is their major appeal. They also have a long lifespan of around 14 to 16 years. For a breed so focused on companionship, those years feel especially meaningful.
Happy, outgoing and friendly to humans and furry friends alike, the Havanese is the person commanding the room in any party you’ve ever walked into. They are typically vocal and happy to entertain guests with their silly nature or alert you when the delivery person leaves a package. It should come as no surprise that this happy-go-lucky pup, with its cheerful disposition and affectionate nature, also makes an ideal therapy dog.
#13. Chinese Crested

Both hairless and powder puff varieties of the Chinese Crested can live well into their teenage years with regular vet exams, a healthy diet, and regular exercise. If you have a hairless Chinese Crested, make sure to protect them from sunburns, either with clothing or dog-safe sunscreen. That’s a simple precaution with a big payoff.
The Chinese Crested is one of the few breeds described as catlike, a comparison they earned from a fondness for sitting in high places. They’re unusual in appearance and personality alike, which tends to make their owners fiercely devoted to the breed. Their modest exercise needs and adaptable temperament make them a strong fit for apartment living.
#14. Lhasa Apso

The Lhasa Apso exists as a utility breed that Tibetan monks developed for the purpose of protecting their monasteries. These dogs show their love towards family members, but they remain suspicious of unfamiliar people. The combination of independence and watchdog behavior creates an appealing personality.
The combination of proper weight management and a nutritious diet enables Lhasa Apsos to live beyond 15 years. Their moderate energy level suits apartments, and their long life often reflects stable home environments. They are genuinely ancient dogs with a heritage that stretches back over a thousand years, which lends them a certain dignified quality even in their smallest moments.
#15. Lancashire Heeler

The Lancashire Heeler had the longest average lifespan of any breed studied in a major Scientific Reports study, at 15.4 years. This breed typically weighs no more than 17 pounds and has a short, stout body similar to a Corgi. For a breed that only received American Kennel Club recognition in 2024, it’s already turning heads for all the right reasons.
The AKC gives them the highest possible scores for affection and how good they are with children and other dogs. They’re energetic, intelligent, and surprisingly robust given their compact build. If you haven’t heard of this breed yet, it’s worth a closer look, especially for families who want a spirited and enduring companion.
#16. Miniature Schnauzer

The Miniature Schnauzer is one of the most consistently healthy small breeds recognized by major kennel clubs, with a typical lifespan ranging from 12 to 15 years. Their wiry double coat, distinctive beard, and eyebrows give them an almost theatrical appearance that perfectly suits their alert, spirited personality. They’re curious, confident, and genuinely entertaining to live with.
Miniature Schnauzers were originally bred in Germany for farm work and ratting, which means they carry a working dog’s energy and stamina in a compact body. They tend to be prone to certain metabolic conditions like hyperlipidemia, so routine bloodwork as they age is a smart habit. Their intelligence means they respond well to training, and a mentally engaged Schnauzer is generally a healthy one.
#17. Cairn Terrier

Cairn Terriers are shaggy, athletic dogs bred in Scotland to hunt foxes and other small mammals. The breed saw a boost in popularity after 1939, when a Cairn Terrier named Terry starred as Toto in The Wizard of Oz. Even before that Hollywood moment, they were known for their remarkable durability and hardiness in rough Scottish terrain.
Their typical lifespan runs from 13 to 15 years, and they bring a feisty, affectionate energy to daily life. They’re low-shedding, relatively easy to groom, and pack a surprising amount of heart into a body that rarely tops 14 pounds. Like most terriers, they need consistent exercise and mental engagement to stay at their best.
#18. Rat Terrier

Whether you choose the miniature, which stands at about 13 inches, or the standard size, which comes in at around 18 inches, you’re signing up for fun and feisty times with these compact and robust American charmers. Since they’re one of the longest-living dog breeds, you have plenty of time to enjoy them. Legend has it that Teddy Roosevelt coined the breed name, as these dogs helped combat a rat infestation in the White House. Yet “rat” hardly seems appropriate for a dog with such an adorable and friendly face.
Rat Terriers are lean, athletic, and surprisingly gentle once they’ve earned your trust. They adapt well to both active homes and quieter environments, as long as they get enough movement and stimulation each day. Their generally sound genetics give them an edge, and well-cared-for individuals regularly reach 15 to 18 years.
#19. Bichon Frise

Bichons Frise are happy little dogs who can fit happily into almost any family. Their curly white fur needs extensive grooming, both at home and from a professional. Along with daily brushing and frequent baths and haircuts, you’ll need to keep this bright, friendly dog lavished with attention.
The Bichon Frise typically lives between 14 and 15 years, with some individuals reaching beyond that with attentive care. What these dogs lack in size, they make up for in heart. Bichons are known for being curious, friendly, and eager to please, which makes them easy to train in both basic commands and fun tricks. They’re also often recommended for allergy-sensitive households, given their low-shedding coats.
#20. Japanese Chin

An ancient dog breed with a noble past, Japanese Chin were once popular among Japanese aristocracy. With a long, silky coat and expressive eyes that give them a look of wonder, Chin are regal and elegant while still being tiny, cute dogs. Their typical lifespan runs from 10 to 12 years, which is slightly shorter than some other breeds on this list, but individual dogs with attentive care have done considerably better.
Japanese Chin are quiet, graceful, and nearly catlike in their independence and cleanliness, often grooming themselves much the way cats do. They’re devoted to their families but can be reserved with strangers. Owners who understand their sensitive temperament tend to build remarkably close bonds with them across many years.
#21. Affenpinscher

German for “monkey terrier,” it’s easy to see how the Affenpinscher got their name: their distinctive flat, bearded face makes this small dog breed look more like a monkey than a pup. Like other little dogs, Affenpinschers have a long lifespan that can reach 15 years or more. They’re an old European breed with a personality that rewards patient owners enormously.
Despite their scruffy, somewhat comical appearance, Affenpinschers are confident, curious, and notably self-assured. They tend to be in good health throughout their lives, with fewer breed-specific conditions than many of their small-dog peers. Their wiry coat needs regular grooming, but beyond that, they’re a relatively low-maintenance companion for someone who appreciates a dog with genuine character.
What Makes Small Dogs Live So Long

Small dogs are believed to live longer than large breeds because of their lower growth rate, which results in lower metabolic demand and lower oxidative stress on cells. It’s a plausible explanation, though researchers continue to study the exact mechanisms. Scientists have long been baffled about why small dog breeds tend to live longer than large dog breeds, since in the rest of the animal kingdom, size seems to positively correlate with longevity.
Genetics play a significant role, but proper diet, exercise, and regular vet check-ups are crucial for maintaining your dog’s health. Breed is only the starting point. The best way to help your dog live out their life to the fullest is to consult with your veterinarian. Your vet can help you put together a plan for your dog’s well-being that includes proper nutrition, preventative care, and exercise, so that your dog stays healthy and active into their golden years.
Conclusion

Choosing a small dog isn’t just a matter of size or convenience. For many owners, it turns into a relationship that quietly shapes a decade or two of their life. The breeds on this list are proof that compact dogs can be profoundly enduring companions, often outlasting expectations by years.
The science points to genetics, metabolism, and body size as key factors, but every long-lived dog also reflects the care poured into them. Good nutrition, routine vet visits, dental hygiene, and a life filled with mental stimulation all make a measurable difference. No number of favorable genes can replace attentive ownership.
There’s something quietly moving about a small dog that grows old alongside you. The years accumulate in shared routines, familiar walks, and a presence that becomes so woven into daily life that its absence would be difficult to imagine. If longevity matters to you when choosing a dog, these 21 breeds offer some of the most generous timelines in the canine world.
