Today, we revisit one of our favorite episodes from the past year: about the science of how dogs make us calmer, happier — and maybe even more trusting.

If you want more optimistic content on the weekends, let us know at podcasts@washpost.com and maggie.penman@washpost.com – and check out our newsletter.

Today’s show was produced and hosted by Maggie Penman and reported by Kyle Melnick. It was edited by Allison Klein and mixed by Ted Muldoon.
