Dogs are true life-savers, and not just for their unconditional love.
A new study found that owning a pet, especially a dog, may help maintain a healthy heart.

Researchers also say pets reduce stress and increase socialization.
The study was published Friday in the journal, 'Mayo Clinic Proceedings.'
