Your heart’s best friend: A canine companion?

Living with a dog may help protect against heart disease and help people live longer. Potential perks of dog ownership include lower blood pressure, a lower resting heart rate, and possible small improvements in cholesterol levels, perhaps because dog owners are less sedentary than non-owners. But dogs may also provide emotional and social benefits, such as reducing loneliness and anxiety, encouraging people to interact with neighbors, and fostering stronger ties to the community.
