Give your heart to dog and live longer

Give your heart to dog and live longer

Washington (ISJ): Leave your health to dogs could turn out to be a great idea, if you have a pet dog at home, especially for those who have had heart attacks or strokes.

New research shows association with dog gives its owner a longer life, reinforcing earlier studies that it alleviates social isolation, improves physical activity and lowers blood pressure.

"While these non-randomized studies cannot prove that adopting or owning a dog directly leads to reduced mortality, these robust findings are certainly at least suggestive of this," said Dr. Glenn N. Levine, who led a committee that wrote a 2013 report about pet ownership for the American Heart Association.

A study from Sweden compared dog owners and non-owners after a heart attack or stroke. Records of nearly 182,000 people who'd had heart attacks and nearly 155,000 people who'd had strokes were examined. Dog ownership was confirmed with data from the Swedish Board of Agriculture, where registration of dog ownership has been mandatory since 2001, and the Swedish Kennel Club, where pedigree dogs have been registered since 1889.

A comparison of the data showed, dog owners who lived alone had a 33% lower risk of dying after being hospitalized for a heart attack. For dog owners who lived with a partner or child, the risk was 15% lower.

In the case of stroke survivors, who had the company of their pets showed the risk of death after hospitalization for those who lived alone was 27% lower. It was 12% lower for those who lived with a partner or child.

"We know that social isolation is a strong risk factor for worse health outcomes and premature death," said study co-author Dr. Tove Fall, a doctor of veterinary medicine and a professor at Uppsala University in Sweden. "Previous studies have indicated that dog owners experience less social isolation and have more interaction with other people. Furthermore, keeping a dog is a good motivation for physical activity, which is an important factor in rehabilitation and mental health."

The second research in Canada reviewed patient data from more than 3.8 million people in 10 separate studies.

Compared to non-owners, dog owners had a 24% reduced risk of dying from any cause; a 31% reduced risk of dying from cardiovascular-related issues; and a 65% reduced risk dying after a heart attack.

The study did not account for factors such as better fitness or an overall healthier lifestyle that could be associated with dog ownership, said co-author Dr. Caroline Kramer, an endocrinologist and clinician scientist at Leadership Sinai Centre for Diabetes at Mount Sinai Hospital in Toronto. "The results, however, were very positive."

As a dog owner herself, Kramer said adopting her miniature Schnauzer, Romeo, "increased my steps and physical activity each day, and he has filled my daily routine with joy and unconditional love."

Tove, however, cautioned more research needs to be done before people are prescribed dogs for health reasons. "Moreover, from an animal welfare perspective, dogs should only be acquired by people who feel they have the capacity and knowledge to give the pet a good life."
