Dog Day Afteroon

If there’s one place that dog people feel at home, it’s a dog park. We’ll talk this hour about the culture of these puppy playgrounds – and about how they can be microcosms of the larger world – with Matthew Gilbert. He writes about his time hanging out in Boston’s Amory Park with his Yellow Lab, Toby, in Off the Leash: A Year at the Dog Park (Thomas Dunne Books).
