Pooling the data of 3 837 005 participants, dog ownership was associated with a 24% risk reduction for all-cause mortality as compared to nonownership (relative risk, 0.76; 95% CI, 0.67–0.86).
In analyses of studies evaluating cardiovascular mortality, dog ownership conferred a 31% risk reduction for cardiovascular death (relative risk, 0.69; 95% CI, 0.67–0.71; I2, 5.1%).
Dog ownership is associated with lower risk of death over the long term, which is possibly driven by a reduction in cardiovascular mortality. These results hold implications for future studies on lifestyle interventions.
