Pets are friends, too Pets can provide social support, which increases the odds of survival after a heart attack, relieves depression among AIDS patients, and lowers the levels of blood pressure and blood lipids that contribute to cardiovascular risk (Allen, 2003; McConnell et al., 2011; Wells, 2009). To lower blood pressure, pets are no substitute for effective drugs and exercise. But for people who enjoy animals, and especially for those who live alone, pets are a healthy pleasure (Allen, 2003).
