This is what I found on CNN.com:

(CNN) — Need an excellent reason to add a dog to your life? How about living longer?

“Our analysis found having a dog is actually protective against dying of any cause,” said Mount Sinai endocrinologist Dr. Caroline Kramer, lead author of a new systematic review of nearly 70 years of global research published Tuesday in “Circulation,” a journal of the American Heart Association.

The review of the health benefits of man’s best friend analyzed research involving nearly 4 million people in the United States, Canada, Scandinavia, New Zealand, Australia and the United Kingdom.
