Lifespan & Health Overview

Pick a breed to see its typical lifespan range from our dataset, charted against the all-breed average of about 12.5 years. Below the chart, the tool lists the conditions that breed is known to be prone to, plus a short checklist of what to ask your vet about. Small breeds tend to outlive large ones — many of the longest-lived are dogs that stay small.

This is general guidance for planning and early screening — not a diagnosis, and not a prediction about any individual dog.

Where do the lifespan numbers come from?

Our 42-breed dataset's lifespan ranges. The ~12.5-year bar is the all-breed average shown for comparison, so you can see at a glance whether a breed tends to live longer or shorter than typical.

Does my dog definitely get these health issues?

No. These are conditions the breed is known to be prone to — risk factors, not certainties. Screening, weight management, and regular vet visits are how you stay ahead of them.

What should I ask my vet about?

Screening tests for the listed conditions, a weight-management plan (healthy weight adds years), and a dental care schedule.

Do any dogs live to 20 years?

Rarely, but it happens — almost always small breeds. In our dataset the longest-lived ranges top out at 16–18 years (Shih Tzu, Poodle, Chihuahua up to 17). Verified cases into the late 20s exist but are extreme outliers. For planning purposes, treat 15+ as an excellent run for a small dog.

What is the average age of a dog’s death?

Around 12–13 years across all breeds and sizes — this tool charts each breed against an all-breed average of about 12.5. Small breeds skew higher (often 14–16), giant breeds lower (sometimes under 10). Pick a breed above to see where it sits against that average.
