If you're seeking reasons to welcome a dog into your family, consider emerging evidence on child health. A recent study shows infants in homes with pets—70 percent featuring dogs—exhibit higher levels of two key microbes associated with reduced risks of allergic diseases and obesity.
These findings build on two decades of research indicating children raised with dogs face lower asthma risks. Experts theorize early exposure to microbes from dirt and bacteria fosters immune system development, though it's unclear if benefits stem directly from pets or indirect human contact. While promising, it's too soon to draw firm conclusions—hold off on adopting a pet based solely on this.
