(CNN) – Dogs could add years to your life. That’s according to new research from the University of Toronto.
Researchers analyzed data from four million people in six countries.
They found dog owners had a 24-percent lower risk of dying early. For those who had already had a heart attack, the risk of dying from cardiovascular disease was lowered by 31-percent.
A major factor could be pet owners who walk their dogs got up to 30 minutes of exercise a day.
Studies also show petting dogs can reduce blood pressure, anxiety, and depression.
