Jason Mogavero is a dog walker based in Washington, D.C. who looks after a dozen or more pups every day. He went in deep with us on the particulars of his job, from the way he gets to know new clients—human and animal alike—to the way he arranges his schedule. Along the way, he covered a lot of other ground, discussing the contents of his fanny pack, how he keeps bones out of the dogs’ mouths, and much more. And in a *Slate Plus extra, Moagavero tells us about his nemesis, a unicycling dog walker who sounds an awful lot like a Portlandia joke come to life.
