Did you know that breastfeeding AND growing up with a dog helps protect a baby’s immune health?
Research spanning more than two decades shows children raised with dogs have lower rates of asthma and allergic disease.
Evidence suggests why: infants exposed to pets (particularly dogs) plus adding breastfeeding into the mix, have greater gut microbiome diversity during the first three months, a critical window for immune development.
In other words, dogs act as microbial conduits and breastmilk helps those microbes do meaningful work.
