21 Dog Breeds With the Longest Lifespans in a Major Study

Anyone who has loved a dog has probably wished for the same impossible thing: a few more years together. No breed comes with a guaranteed lifespan, but some do tend to stick around longer than others.

A major 2024 study published in Scientific Reports analyzed 584,734 dogs in the United Kingdom, including 284,734 that had died, to estimate longevity across 155 recognized breeds. The median lifespan for all dogs in the study was 12.5 years, but several breeds reached 14 years or more. Median matters here: it means half of the dogs in that group lived longer and half died younger. These numbers are useful population estimates, not expiration dates for individual pets.

Median lifespan in the study: 14.0 years. Italian Greyhounds may look delicate, but these miniature sighthounds are athletic dogs with a serious instinct to chase anything that moves. The American Kennel Club lists them at just 7 to 14 pounds and gives the breed a typical lifespan of 14 to 15 years, which lines up closely with the UK study. They are affectionate companions, but those long, fine-boned legs also mean owners need to be a little more careful about falls and rough play than they would with a sturdier small dog.

Median lifespan in the study: 14.0 years. The Cairn Terrier packs plenty of personality into a roughly 13- to 14-pound body. Originally developed in Scotland to chase vermin through rocky terrain, Cairns remain alert, active, and curious dogs. The AKC gives them a typical lifespan of 13 to 15 years. That combination of small size and sturdy terrier build puts them right at home among the longer-lived breeds in the UK longevity study.

Median lifespan in the study: 14.0 years. Poodles are much more than elaborate show-ring haircuts. They are highly intelligent, active dogs with a history as water retrievers. Poodles come in Toy, Miniature, and Standard sizes, so an individual dog's size and health profile can vary considerably. The UK study nevertheless recorded a 14-year median for dogs identified as Poodles overall, putting the breed among the longest-lived groups in the dataset.

Median lifespan in the study: 14.0 years. Australian Cattle Dogs are muscular, intensely intelligent herding dogs that were built for long days of work rather than lounging around the house. The AKC lists the breed at roughly 35 to 50 pounds with a typical lifespan of 12 to 16 years. They generally need plenty of exercise and mental stimulation, making them a much better match for an active owner than someone looking for a permanent couch companion.

Median lifespan in the study: 14.0 years. Norwich Terriers are tiny working dogs with much bigger personalities. The breed standard calls for an ideal weight around 12 pounds, but these are not fragile lap dogs. Norwich Terriers were developed to hunt vermin, and many still bring plenty of energy, curiosity, and prey drive into the home. Their combination of small size and sturdy construction fits the broader pattern researchers found, with smaller dogs generally tending to outlive larger ones.

Median lifespan in the study: 14.0 years. The German Spitz Mittel is the medium-size version of Germany's classic spitz breed, recognizable by its thick double coat, pointed ears, and tail carried over the back. Britain's Royal Kennel Club describes the Mittel as intelligent and full of character, with a lifespan generally exceeding 12 years. The breed's 14-year median in the study puts it comfortably above the 12.5-year median recorded across the entire dog population.

Median lifespan in the study: 14.0 years. Sometimes described as a Viking-era cattle dog, the Swedish Vallhund is short-legged but anything but lazy. These compact herders generally weigh about 20 to 35 pounds and are known for being energetic, watchful, and social. The AKC lists a usual lifespan of 12 to 15 years, while the much larger UK study landed almost exactly in the middle of that range at 14 years.

Median lifespan in the study: 14.0 years. Beneath all that hair is a surprisingly sturdy little dog. Lhasa Apsos were developed in Tibet as alert indoor watchdogs, and the modern breed still tends to combine independence with a strong attachment to its people. The AKC lists Lhasas at roughly 12 to 18 pounds and gives them a typical lifespan of 12 to 15 years. In the UK study, the middle dog reached 14 years.

Median lifespan in the study: 14.0 years. The Miniature Dachshund was missing from the original version despite tying the other breeds in this group. Dogs Trust specifically highlighted the breed among the longer-lived dogs in its study. These tiny hounds were bred around a very distinctive long-backed, short-legged body shape, so longevity does not mean the breed is free of health concerns. Still, across the UK population studied, Miniature Dachshunds reached a median age of 14 years.

Median lifespan in the study: 14.0 years. The Welsh Springer Spaniel is another breed that belonged in the original list but was left out. These red-and-white sporting dogs are considerably larger than most of the breeds here, generally weighing about 35 to 55 pounds. The AKC describes them as vigorous, upbeat bird dogs that can also make affectionate companions at home. Their 14-year median is especially notable because the study generally found shorter lifespans as body size increased.

Median lifespan in the study: 14.1 years. The Large Munsterlander is one of the biggest surprises on the list. This German hunting breed is a full-size, athletic gundog rather than a tiny companion breed. Britain's Royal Kennel Club describes it as energetic, loyal, affectionate, and built to work both on land and in water. Since larger dogs usually have shorter lifespans, a 14.1-year median makes the Large Munsterlander a genuine outlier in the study.

Median lifespan in the study: 14.2 years. Schipperkes are small Belgian dogs originally associated with barges, where they served as watchdogs and ratters. They generally weigh about 10 to 16 pounds, but nobody appears to have told them they are small. The AKC describes the breed as alert, curious, and confident, with plenty of energy packed into a compact frame. Its published lifespan range of 12 to 16 years fits comfortably around the study's 14.2-year median.

Median lifespan in the study: 14.2 years. Border Terriers were bred to be tough enough to follow horses and small enough to pursue foxes into tight spaces, which helps explain their combination of compact size and seemingly endless enthusiasm. Adults usually weigh somewhere around 12 to 15 pounds. The AKC puts their typical lifespan at 12 to 15 years, while the study's 14.2-year median places them squarely among the longest-lived breeds analyzed.

Median lifespan in the study: 14.2 years. The Coton de Tulear is a small companion breed from Madagascar, named for its soft, cotton-like coat. The AKC describes Cotons as bright, playful, and strongly attached to their people. Most weigh roughly 8 to 15 pounds, depending on sex, and the AKC lists a notably broad lifespan range of 15 to 19 years. The UK dataset came in somewhat lower at a 14.2-year median, a good reminder that breed-guide ranges and measured population data are not the same thing.

Median lifespan in the study: 14.2 years. Lakeland Terriers were developed in England's Lake District to work around farms and hunt foxes. Today they remain confident, energetic little dogs that generally weigh around 17 pounds. The AKC lists their typical lifespan at 12 to 15 years. In the large UK study, Lakelands landed toward the upper end of that range and were specifically identified by researchers as one of the breeds at relatively low risk of early death.

Median lifespan in the study: 14.5 years. Cuba's national dog is a small, outgoing companion breed that generally weighs 7 to 13 pounds. Havanese are known for being social, intelligent, and trainable, although that silky coat requires regular upkeep. The AKC gives the breed a typical lifespan of 14 to 16 years, almost perfectly surrounding the 14.5-year median found in the UK research.

Median lifespan in the study: 14.5 years. The Papillon gets its name from those enormous butterfly-shaped ears, but there is considerably more dog here than the five-to-10-pound package might suggest. Papillons are alert, athletic, and intelligent toy dogs that regularly compete in activities such as agility. The study found a 14.5-year median lifespan, putting them among the handful of breeds that cleared the 14-year mark by a comfortable margin.

Median lifespan in the study: 14.6 years. The Shiba Inu is an ancient Japanese hunting breed that has become a hugely recognizable companion dog. Shibas are compact but muscular, alert, independent, and often a little more opinionated than first-time owners expect. In the Scientific Reports study, the breed reached a 14.6-year median and was specifically identified as one of the breeds with a relatively low risk of early death.

Median lifespan in the study: 14.9 years. The fluffy white Bolognese is an Italian companion breed that usually weighs only about 6 to 10 pounds. The AKC describes these dogs as playful, easygoing, and devoted. Interestingly, the AKC's general breed profile lists a 12-to-14-year lifespan, while this particular UK dataset produced a higher 14.9-year median. That difference is exactly why population studies should be treated as estimates from a particular group of dogs rather than universal rules.

Median lifespan in the study: 15.2 years. Tibetan Spaniels are not really spaniels in the traditional sporting-dog sense. These small dogs were developed around Tibetan monasteries, where their alert nature made them useful sentinels. They stand only about 10 inches tall but tend to be confident, curious, and independent thinkers. At 15.2 years, the Tibetan Spaniel had the second-highest median lifespan of all 155 recognized breeds analyzed.

Median lifespan in the study: 15.4 years. The Lancashire Heeler took the top spot in this particular dataset. The compact British herding breed generally weighs only about 9 to 17 pounds and combines cattle-driving instincts with the enthusiasm of a small working dog. The AKC fully recognized the breed in 2024 and describes it as intelligent, versatile, and affectionate. One important caveat: only 241 Lancashire Heelers appeared in the study, so the 15.4-year figure is less precise than estimates based on thousands of dogs. Still, no other breed in the analysis produced a higher median.
