Alexandra Horowitz is a dog savant. She runs the dog cognition lab at Barnard College. One of her previous books inside of a dog spent 65 weeks on the New York Times bestseller list, which by the way is 15 dog years. And as I listened to her book recently, I had this strange feeling like she'd snuck into my apartment and watched our first few weeks learning to live with Cisco. Just like the human teenagers, sometimes erratic behavior, distant and argumentative one moment, really sweet the next.
