People over the years have claimed that their dogs make them feel good emotionally. Some studies over the years have looked at the interaction between humans and dogs, working toward concluding if there is a health benefit like lowering blood pressure or risk of heart disease. A new study out of the University of Arizona is exploring whether dogs can improve human health by having a probiotic effect on the body. The research will focus specifically on dogs' effect on the health of older adults.

This is great news and also may actually be the final push for me to get a dog.
