As if we needed any more proof for the importance of dogs in our lives, a recent study, published in the American Heart Association Circulation Journal suggests that owning a canine companion boosts longevity. This conclusion is based on no less than 70 years of observation and analysis. The researchers looked at studies published from 1950 to May 2019 that evaluated dog ownership and its association with mortality. The research included 10 studies that yielded data from more than 3 million participants.
