We treat dogs like they're part of the family. But do they know they are a different species, or do they think they're just short, four-legged people?

In this episode, canine cognition researcher Alexandra Horowitz helps us puzzle out this question. We’ll also find out what happens (or doesn’t) when a dog looks in the mirror. Dogs are always dozing, and we’ll check in to see if they are dreaming too. And, we take a quick trip around the world in the language of barks. All that, plus a brand new Mystery Sound!
