Longest-living dog breeds
Measured in the largest study of dog lifespan to date, the longest-lived breeds are small and medium-muzzled: the Lancashire Heeler at 15.4 years, then the Tibetan Spaniel, Shiba Inu, Papillon and Lakeland Terrier. Below: the measured lists, then all 277 breeds ranked by their breed-standard lifespan range.
Measured: the longest-lived breeds in UK data
Two studies measured actual lifespans rather than breed-standard ranges. McMillan et al. (2024) reported median lifespan for 155 breeds; VetCompass life tables (Teng et al., 2022) reported life expectancy at birth for the 18 most common breeds. The two figures are not directly comparable, so they are shown separately.

Common breeds only (30,563 dogs). The Jack Russell and Yorkshire Terrier led this list; the French Bulldog was last.
All breeds ranked by lifespan range
Breed-standard ranges from AKC breed data, sorted by the middle of the range. Standards describe what a breed typically reaches, not what every dog does: body condition alone moves lifespan by up to 2.5 years. Where a breed appears in a UK study, the measured figure is shown alongside.

What long-lived breeds have in common
- Small size. Almost every breed with a 14-year-plus range weighs under 30 lb. Large dogs grow faster and develop cancer, heart disease and joint disease earlier; giant breeds rarely pass 10.
- A medium muzzle. Flat-faced breeds had a median of 11.2 years against 12.8 for medium-muzzled breeds in the 2024 study. Airway disease, heat intolerance and spinal problems account for most of the gap.
- No exaggerated build. Long backs (disc disease), very deep chests (bloat) and extreme size each carry a specific killer. The longest-lived breeds are unremarkable in shape: terriers, spaniels, small spitz types and companion breeds.
- Working origins. Many of the measured leaders were bred for a job and selected for soundness rather than looks.
Longevity is not only breed
Within any breed the spread is wide. The measured levers: keep the dog lean (overweight dogs lived 5 months to 2.5 years less across 12 breeds; lean-fed Labradors lived 1.8 years longer than free-fed littermates), neuter (about a year in UK life tables), treat dental disease, and screen for the breed's known conditions early. Each breed page lists what to screen for; the lifespan calculator shows the size of each effect.
Frequently asked questions
What dog breed lives the longest?
In the largest study of dog lifespan (584,734 UK dogs, McMillan 2024) the longest-lived breed was the Lancashire Heeler at 15.4 years, followed by the Tibetan Spaniel (15.2), Shiba Inu (14.6), Papillon (14.5) and Lakeland Terrier (14.2). By breed-standard range, the top of the list is dominated by toy and small breeds with 14 to 18-year ranges.
Do small dogs live longer than big dogs?
Yes, consistently. Small breeds had a median of 12.7 years, medium 12.5 and large 11.9 in the 2024 UK study, and the shortest-lived breeds were all giants. Faster growth in big dogs brings cancer, heart disease and joint failure earlier.
What is the longest-living large dog breed?
By breed-standard range the Hamiltonstovare tops the large and giant list at 14 to 17 years. See the full ranking of longest-living large dog breeds.
Do mixed-breed dogs live longer than purebreds?
Not in the most recent large dataset: purebreds had a median of 12.7 years and crossbreeds 12.0, likely because many popular crosses involve flat-faced or giant parents. Earlier US studies found crossbreeds outliving purebreds by about a year. It depends on the breeds in the mix.
What is the oldest dog ever?
Guinness recognizes Bluey, an Australian Cattle Dog, at 29 years 5 months. Bobi, a Portuguese dog claimed to be 31, had the title revoked in 2024 for lack of evidence. Dogs past 20 are extremely rare in any breed.
Which long-lived breed is right for a first-time owner?
Longevity should be one factor among several. Among the long-lived breeds, those with moderate grooming and exercise needs and no extreme conformation (medium muzzle, no exaggerated build) tend to be easiest, and they also avoid the airway and spinal problems that cut life short in flat-faced and long-backed dogs.
