Want to live longer? Get a dog!

Those who own a dog as a pet have a much lower risk of death. At least that’s what the authors of a study that analyzed 3.4 million Swedish citizens say.

“A very interesting finding in our study was that dog ownership was especially prominent as a protective factor in persons living alone, which is a group reported previously to be at higher risk of cardiovascular disease and death than those living in a multi-person household,” said Mwenya Mubanga, an author on the study and PhD student at Uppsala University.

The specialist added as possible explanations to reduce the risk of cardiovascular disease that a dog has the effect of raising social or personal welfare, or by changing the micro-bacterial fauna of their masters, informs CNN.

It is believed that a dog can positively influence the micro-bacterial fauna of their masters through the new species they introduce into the human environment.
