Which Dog Breed Lives the Longest? 12 Long-Lived Breeds Ranked
Which dog breed lives the longest? We rank 12 breeds by verified lifespan data, compare health risks, and help you choose a long-lived companion.
How We Selected These Long-Lived Breeds
Not every breed with a high maximum lifespan earns a spot here. Our ranking relies on four weighted criteria drawn from AKC longevity data, peer-reviewed veterinary studies, and breed club health surveys:
- Median lifespan (40% weight): Minimum 14 years median, sourced from breed-specific health surveys and the Merck Veterinary Manual.
- Quality of life in senior years (25% weight): Breeds prone to debilitating chronic pain or severe cognitive decline by age 10 were penalized, even if they technically live long.
- Hereditary disease burden (20% weight): Breeds with fewer than 3 high-prevalence genetic conditions (per OFA and breed club registries) ranked higher.
- Accessibility (15% weight): Breeds must be obtainable through responsible breeders or rescue networks in the U.S. without extreme waitlists or five-figure price tags.
The Longevity Advantage: Why Smaller Breeds Dominate
Before we rank individual breeds, it helps to understand the biology. A landmark 2013 study published in the American Naturalist analyzed over 56,000 dogs across 74 breeds and confirmed what veterinarians have long observed: for every 4.4 pounds (2 kg) of body mass, a dog's lifespan decreases by approximately one month. Giant breeds like Great Danes average 7–10 years, while toy breeds routinely reach 15–18 years.
The mechanism involves several factors: larger dogs grow faster, which accelerates cellular aging; they carry higher oxidative stress loads; and their bodies endure greater mechanical strain on joints and organs. That said, size isn't destiny. Some medium-sized breeds outperform expectations through what geneticists call selective breeding for functional longevity — dogs bred for working roles that required sustained health over many years.
12 Dog Breeds That Live the Longest, Ranked
1. Chihuahua — Median Lifespan: 15–17 years
Size class: Toy (3–6 lb / 1.4–2.7 kg) | Key longevity trait: Extremely low hereditary disease burden
Chihuahuas consistently top longevity lists because they combine tiny body mass with surprisingly robust genetics. The AKC breed standard describes a compact, well-balanced dog, and responsible breeders screen for the few conditions that do appear: patellar luxation, cardiac disease (primarily mitral valve disease in older dogs), and hypoglycemia in puppies under 6 months. A healthy Chihuahua living to 18 or even 20 years is not unusual — the oldest verified Chihuahua, Megabyte, lived to 20 years and 265 days.
Why #1: No other AKC-recognized breed combines this median lifespan with such low veterinary costs. Annual care for a senior Chihuahua averages $400–$700, compared to $900–$1,500 for similarly aged medium breeds.
2. Jack Russell Terrier — Median Lifespan: 14–16 years
Size class: Small (9–15 lb / 4–7 kg) | Key longevity trait: Intense functional fitness from working-line breeding
Bred to chase foxes out of burrows, Jack Russell Terriers were selected for stamina, courage, and soundness — traits that translate directly into longevity. These dogs maintain muscle tone and cardiovascular fitness well into their teens when given adequate exercise (minimum 60 minutes of vigorous activity daily). Primary health concerns include primary lens luxation (PLL), Legg-Calvé-Perthes disease, and patellar luxation, but the overall hereditary burden is low compared to most terrier breeds.
Why #2: The combination of working-dog genetics and moderate size creates a breed that doesn't just live long — it stays active long. Many Jack Russells compete in agility into their 12th year.
3. Toy Poodle — Median Lifespan: 14–16 years
Size class: Toy (4–6 lb / 1.8–2.7 kg) | Key longevity trait: Exceptional genetic diversity within the breed pool
Toy Poodles benefit from being part of the broader Poodle gene pool (Standard, Miniature, and Toy), which maintains greater heterozygosity than many toy breeds. They're highly intelligent and trainable, which reduces stress-related behavioral problems that can shorten lifespan indirectly (surrender, rehoming trauma, anxiety-driven conditions). Health screenings should cover progressive retinal atrophy (PRA), von Willebrand disease, and Addison's disease.
Why #3: Their hypoallergenic coat makes them viable for owners with allergies — a practical factor since allergic owners sometimes rehome dogs, disrupting the stability that supports longevity.
4. Dachshund (Miniature) — Median Lifespan: 14–16 years
Size class: Small (8–11 lb / 3.6–5 kg) | Key longevity trait: Compact body with proportionally strong cardiovascular system
Miniature Dachshunds outlive their Standard counterparts (12–14 years) partly due to reduced spinal loading. The breed's famous long-back conformation does create intervertebral disc disease (IVDD) risk — approximately 25% of Dachshunds will experience IVDD in their lifetime, according to veterinary orthopedic data. However, miniatures carrying less weight experience less disc compression. Responsible breeders now screen for the FGF4 retrogene insertion associated with chondrodystrophy.
Why #4: Despite the IVDD concern, miniatures that maintain ideal weight and avoid stair-jumping frequently reach 16+ years with good mobility.
5. Yorkshire Terrier — Median Lifespan: 14–16 years
Size class: Toy (4–7 lb / 1.8–3.2 kg) | Key longevity trait: Low exercise demands reduce injury risk over lifetime
Yorkies combine toy-breed longevity with a relatively sturdy constitution for their size. Their primary health vulnerabilities are tracheal collapse (managed by using a harness instead of a collar), dental disease (requiring daily brushing and professional cleanings every 6–12 months), and portosystemic shunt, a liver vascular anomaly that can be surgically corrected when caught early.
Why #5: Low impact exercise needs mean fewer traumatic injuries — a significant factor since trauma is a leading cause of death in dogs under 10 years.
6. Pomeranian — Median Lifespan: 14–16 years
Size class: Toy (3–7 lb / 1.4–3.2 kg) | Key longevity trait: Hardy Spitz-type genetics in a toy package
Pomeranians descend from large Spitz-type working dogs (think Samoyeds and Malamutes), and they retain some of that genetic hardiness despite centuries of size reduction. They're prone to tracheal collapse and luxating patellas, but serious cardiac disease tends to appear later in life than in breeds like Cavalier King Charles Spaniels. Dental care is critical — Poms often lose teeth early without consistent oral hygiene.
Why #6: The Spitz ancestry provides a genetic resilience that many purpose-bred toy breeds lack, giving Poms a survival edge in senior years.
7. Shih Tzu — Median Lifespan: 13–16 years
Size class: Small/Toy (9–16 lb / 4–7.3 kg) | Key longevity trait: Low-stress temperament reduces cortisol-related aging
Bred exclusively as companion animals for Chinese royalty, Shih Tzus have no working-dog drive that pushes them to physical extremes. Their calm disposition keeps stress hormones low, which may contribute to their consistent longevity. Brachycephalic (short-faced) structure does create some respiratory compromise, but it's less severe than in Bulldogs or Pugs. Watch for renal dysplasia, hip dysplasia, and eye conditions like keratoconjunctivitis sicca (dry eye).
Why #7: Among brachycephalic breeds, the Shih Tzu represents the best longevity-to-companionship ratio, with airway issues manageable through weight control and climate management.
8. Miniature Schnauzer — Median Lifespan: 13–15 years
Size class: Small (11–20 lb / 5–9 kg) | Key longevity trait: Above-average size for lifespan bracket without giant-breed penalties
Miniature Schnauzers occupy a sweet spot: large enough to avoid the fragility issues of ultra-toy breeds (hypoglycemia, tracheal collapse, bone fractures) but small enough to benefit from the size-longevity correlation. They're sturdy, athletic dogs that adapt well to active households. Health concerns include pancreatitis (they have a breed predisposition to hyperlipidemia), urinary stones, and myotonia congenita.
Why #8: Their slightly larger frame gives them a physical durability that toys lack, while still landing well within the long-lived size range.
9. Italian Greyhound — Median Lifespan: 13–15 years
Size class: Small (7–14 lb / 3.2–6.4 kg) | Key longevity trait: Sighthound cardiovascular efficiency in miniature form
Italian Greyhounds are essentially scaled-down sighthounds, and they retain the exceptional cardiovascular fitness of their larger cousins (Greyhounds, Whippets). Their lean build minimizes joint stress, and their short coat makes them easy to groom — a practical advantage for elderly owners. Primary concerns include leg fractures (they have fine bones), dental disease (crowded teeth), and progressive retinal atrophy.
Why #9: The sighthound cardiovascular advantage is real — resting heart rates and cardiac efficiency in IGs mirror their larger relatives, supporting organ longevity.
10. Australian Cattle Dog — Median Lifespan: 13–15 years
Size class: Medium (35–50 lb / 16–23 kg) | Key longevity trait: Outlier longevity for medium-sized working breed
The Australian Cattle Dog breaks the size rule. At 35–50 lb, they should average 11–13 years, but breed health surveys consistently show medians of 13–15 years, with verified cases reaching 20+ (Bluey, an ACD, held the Guinness record at 29 years and 5 months until 2023). Their extreme longevity likely stems from intense selection pressure in Australian ranching — dogs that couldn't work 12+ hours daily in harsh conditions were culled from the breeding pool for generations.
Why #10: They prove that selective working-dog breeding can override the size-longevity correlation, making them the best medium-breed option for longevity seekers.
11. Pembroke Welsh Corgi — Median Lifespan: 12–15 years
Size class: Small-Medium (25–30 lb / 11–14 kg) | Key longevity trait: Sturdy herding-dog constitution with moderate exercise needs
Corgis are deceptively substantial dogs — their short legs carry a dense, muscular body. They're prone to IVDD (similar to Dachshunds), hip dysplasia, and degenerative myelopathy (DM), but responsible breeders now test for the DM gene and avoid breeding carriers. Daily exercise of 45–60 minutes keeps them fit without the joint wear that high-impact activities cause in chondrodystrophic breeds.
Why #11: Their herding-dog intelligence and moderate size make them the most trainable long-lived breed on this list — a practical advantage for owners who want a dog that can learn health-supporting routines (crate rest, medication compliance, calm behavior at vet visits).
12. Border Terrier — Median Lifespan: 13–15 years
Size class: Small (11–15 lb / 5–7 kg) | Key longevity trait: Minimal exaggeration in breed conformation
Border Terriers look like what they are: functional, no-frills working terriers. Their conformation has no extreme features — no shortened muzzle, no elongated spine, no oversized skull requiring cesarean delivery. This "moderation in all things" approach to breeding produces dogs with fewer structural health problems than most purebreds. Canine epileptoid cramping syndrome (CECS) is the breed's most notable hereditary condition, and it's manageable with dietary modification in many cases.
Why #12: They're the closest thing to a naturally-selected dog in the purebred world, and it shows in their health span, not just lifespan.

Honorable Mentions and Breeds to Avoid
Honorable Mentions (Just Missed the Cut)
Rat Terrier (14–16 years): Excellent longevity but limited availability outside the U.S. and sparse breed club health data made ranking difficult.
Papillon (13–15 years): One of the sturdiest toy breeds, but their fine bone structure leads to fracture rates that pushed them just below our top 12.
Schipperke (13–15 years): Remarkably healthy breed with low hereditary disease rates, but rarity in the U.S. limits practical accessibility.
Breeds to Avoid If Longevity Is Your Priority
These breeds have median lifespans below 10 years and carry high burdens of life-limiting hereditary disease:
- Bernese Mountain Dog: Median 6–8 years; extremely high cancer rate (nearly 50% die from malignancy per breed club surveys)
- English Bulldog: Median 8–10 years; brachycephalic obstructive airway syndrome (BOAS), hip dysplasia, and cardiac disease are near-universal
- Great Dane: Median 7–10 years; bloat (GDV), cardiomyopathy, and osteosarcoma are prevalent
- French Bulldog: Median 10–12 years; severe BOAS, spinal disorders, and heat intolerance compromise quality of life even when lifespan reaches the median
- Irish Wolfhound: Median 6–8 years; cardiomyopathy and osteosarcoma are devastatingly common
Decision Framework: Choosing Among the Top 3
The top three breeds on our list — Chihuahua, Jack Russell Terrier, and Toy Poodle — each suit very different lifestyles. Use this framework to narrow your choice:
Step 1: What is your daily exercise capacity?
- Under 30 minutes of light walking → Go to Step 2a (Chihuahua or Toy Poodle path)
- 30–60+ minutes of active exercise (hiking, jogging, fetch sessions) → Go to Step 2b (Jack Russell Terrier path)
Step 2a: Do you have allergies or prefer a low-shed coat?
- Yes, allergies are a concern → Choose the Toy Poodle. Their hair-like coat produces less dander. Budget $600–$900/year for professional grooming every 6–8 weeks.
- No allergies, prefer minimal grooming → Choose the Chihuahua. Smooth-coated Chihuahuas need only weekly brushing. Annual grooming cost: under $100.
Step 2b: Do you want a dog that excels at dog sports?
- Yes — agility, earthdog, rally obedience → Choose the Jack Russell Terrier. They're among the top-performing breeds in agility competition and thrive with structured training challenges.
- No — I want an active companion, not a project → Reconsider the Toy Poodle (highly trainable but lower prey drive than JRTs) or the Border Terrier (#12 on our list — active but less intense).
Step 3: What is your living situation?
- Apartment with no yard → Chihuahua or Toy Poodle (both adapt well to small spaces with indoor play)
- House with fenced yard → Any of the top 3, but Jack Russells particularly benefit from secure yard access for off-leash running (they have extreme prey drive and should never be off-leash in unfenced areas)
- Multi-pet household with cats → Chihuahua or Toy Poodle (Jack Russells have high prey drive and may chase or injure cats without extensive desensitization training)
Maximizing Your Dog's Lifespan Beyond Breed
Breed genetics set the ceiling, but your daily care determines whether your dog reaches it. Research published in the Journal of Veterinary Internal Medicine identifies five modifiable factors with the strongest evidence for extending canine lifespan:
- Body condition management: Dogs maintained at a body condition score (BCS) of 4–5 out of 9 live an average of 1.8 years longer than overweight littermates (Purina Lifespan Study, 2002). Weigh your dog monthly and adjust portions based on activity level.
- Dental care: Periodontal disease is linked to cardiac, hepatic, and renal disease in dogs. Daily tooth brushing with enzymatic canine toothpaste and professional cleanings under anesthesia every 12–18 months (or as recommended by your veterinarian) reduce systemic inflammation.
- Preventive veterinary care: Semi-annual wellness exams for dogs over 7 years catch renal disease, hypothyroidism, and early neoplasia when treatment is most effective. Budget $300–$600/year for senior wellness bloodwork and urinalysis.
- Consistent moderate exercise: Daily activity appropriate to breed and age maintains muscle mass, joint mobility, and cognitive function. Senior dogs benefit from shorter, more frequent walks rather than one long outing.
- Spaying/neutering timing: The evidence on optimal timing is breed-dependent. For small breeds (<20 lb adult weight), spaying/neutering at 6 months has minimal negative impact on longevity. For larger breeds, discuss timing with your veterinarian — some evidence suggests delaying until skeletal maturity (12–18 months) reduces orthopedic disease risk.
Frequently Asked Questions
What is the longest-living dog breed on record?
The longest verified canine lifespan belongs to Bobi, a Rafeiro do Alentejo from Portugal, who lived to 31 years and 165 days (confirmed by Guinness World Records in 2023, though this record was later reviewed). Among commonly owned breeds, the Australian Cattle Dog holds the most verified extreme longevity records, with Bluey living to 29 years and 5 months. However, these are statistical outliers — median lifespan is a more reliable predictor for your individual dog.
Do mixed-breed dogs live longer than purebreds?
The evidence is mixed but leans yes. A 2019 study in the Journal of the American Veterinary Medical Association found that mixed-breed dogs lived an average of 1.2 years longer than size-matched purebreds, attributed to hybrid vigor — reduced expression of recessive hereditary diseases due to greater genetic diversity. However, mixed breeds are not immune to genetic conditions, and a mixed-breed dog inheriting two copies of a deleterious gene will express the disease regardless of breed diversity elsewhere in their genome.
Does dog size really determine lifespan?
Size is the single strongest predictor of canine lifespan, but it's not absolute. The Australian Cattle Dog (35–50 lb, median 13–15 years) outperforms many smaller breeds, while the Bulldog (40–50 lb, median 8–10 years) dramatically underperforms. Conformation (extreme body shapes), genetic diversity, and breeding practices all modify the size-longevity relationship.
How much does a long-lived breed puppy cost?
Prices vary significantly by breed and source. Expect the following ranges from responsible breeders who perform OFA health testing: Chihuahua ($800–$2,500), Jack Russell Terrier ($800–$1,800), Toy Poodle ($1,500–$3,500), Miniature Dachshund ($1,200–$3,000), Australian Cattle Dog ($600–$1,500). Rescue organizations typically charge $200–$500 adoption fees, and adult dogs from rescues can be excellent options — their personality and energy level are already established.
Which long-lived breed is best for a first-time owner?
The Toy Poodle ranks highest for first-time owners among our top 12. They're highly trainable (ranked #2 in Stanley Coren's intelligence rankings), eager to please, adaptable to various living situations, and their grooming needs, while real, are predictable and outsourceable. Jack Russell Terriers, despite their longevity, are challenging for novices due to high prey drive, digging behavior, and exercise demands that many first-time owners underestimate.
