You are the home to trillions of invisible germs. An investigation into the identity of all those bacteria shows that if you own a dog, the two of you share a lot of the same microbes.
The researchers were surprised to find that parents share more bacteria with their dogs than they do with their kids.
“One of the biggest surprises was that we could detect such a strong connection between their owners and pets,” says researcher Rob Knight. “In fact, the microbial connection seems to be stronger between parents and family dogs than between parents and their children.”
Another head-rubbing result from the study: If you want to share more of your skin bacteria with your spouse, get a dog. Couples with canines had more similarities among the bacterial colonies living on their skin and in their intestines than folks without dogs.
