Various researches find that owning a pet can really improve the life of the owner in comparison to those who do not own. The Centers for Disease Control and Prevention revealed that owning pets benefitted the health of owners, as it controlled the blood pressure, cholesterol and triglyceride levels.

Also, the National Institutes of Health-funded study stated that pet owners suffering a heart attack lived a year longer than the patients with heart attack who did not own a pet. Another study commenced by Dr. Allen McConnell, a Professor of Psychology at Miami University in Ohio, stated that pets gave a new meaning to life and changed the way of living of the owners.

Researcher Dr. McConnell’s co-authored "Friends With Benefits: On the Positive Consequences of Pet Ownership” was published in the journal of Personality and Social Psychology. According to the study, the people who owned pats were more confident, careful, liked to socialize with people and were healthier than the ones who did not have pets at their place.

As per McConnell, “I would imagine that someone in a combat situation like in Afghanistan would find real support from a pet, that they would have real benefits from having the pet there especially when a support system like family or relatives are not there, at least in a physical way”.
