On a study break and saw this:
"We essentially want to find out, is a dog acting like yogurt in having a probiotic effect?" said Kelly, who also is a principal research specialist in the Department of Psychiatry and program coordinator for the Human-Animal Interaction Research Initiative.
Existing research shows that dogs and their owners share much of the same gut bacteria over time. In addition, some studies have shown that dogs enhance immune functioning in children, reducing the risk for immune disorders, such as asthma and allergies."
I wish I could participate but I've already got two lil guys I'm apparently sharing gut bacteria with though, I really hope it's true that pets look like their owners since mine are seriously cute. Can't wait until the results are out!
