Overall, people who had any type of pet had better heart health, compared to non-pet owners. But those with dogs fared even better.
The scientists said dog owners were more likely to exercise regularly, eat a healthier diet and have better sugar levels in their blood.
"What we found was that those who own a pet, particularly a dog, were healthier from the cardiovascular standpoint," said co-author Francisco Lopez-Jimenez said in a statement.
This isn’t the first time scientists have linked dog ownership with good health.
In 2017, researchers from Sweden found dog owners who live alone have a 36 percent lower risk of death from cardiovascular disease than those without dogs.
And a 2018 study from scientists at Canisius College discovered women who owned dogs may have better sleep.
