One simple lifestyle choice could help you live longer, says longevity expert
Longevity expert Dan Buettner says owning a dog may be associated with a longer life, particularly through lower risks of cardiovascular disease and early death. He argues that dogs encourage daily activity, provide a sense of purpose and help reduce loneliness, although the evidence describes associations rather than proving that dog ownership directly causes longer lifespans.
Research cited in the article links dog ownership with a 24% lower risk of death from any cause among the general population, and up to a 33% lower risk for people who have experienced a major cardiac event. Dog owners reportedly walk about 22 minutes more per day, while studies also suggest pet interaction may reduce stress and support social connection; a Swedish study of 3.4 million people found lower blood pressure and cardiovascular disease rates among dog owners.
- Dog ownership is linked to longer life and better heart health.
- Dogs encourage exercise, reduce stress and combat loneliness.
- Evidence shows association, not definitive proof of cause and effect.
Both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Owning a dog may support longer life by encouraging regular walking, providing companionship and purpose, and reducing loneliness and stress. Studies reporting lower mortality and cardiovascular risks among dog owners suggest these benefits could be meaningful, particularly for people recovering from serious heart problems, even if they do not prove direct causation.
The case against
The findings show associations, not that owning a dog itself causes people to live longer, because dog owners may differ from non-owners in health, income, lifestyle or social support. Dog ownership also brings costs, responsibilities and potential stress, so presenting it as a broadly beneficial health intervention could overstate what the evidence establishes.
