Canadian researchers analyzed data from nearly four-million people. They found owning a dog, lowered the risk for early an death by 24 percent. 

The research is from the American Heart Association and is published in circulation: Cardiovascular Quality and Outcomes.

Dog owners are also less likely to die after having a heart attack, or from other heart related issues. 

In a second study, scientists studied data from roughly 337,000 heart attack or stroke survivors from Sweden.

They found, those owned a dog, were less likely to suffer an early death from their condition, especially if they lived alone. 

The analysis looked at studies published from 1950 to May 2019, that evaluated dog ownership and its association with mortality. 

The research included 10 studies that yielded data from more than 3 million participants.
