NPR’s Fresh Air recently rebroadcast this interview from 2016, with Alexandra Horowitz. In it, she talks about how dogs form a “picture of the world through smell.” Horowitz founded the Dog Cognition Lab at Barnard College and has written a few books on the nature of dogs:
Being a Dog is of particular interest for those of us who count on our dogs’ noses to do a job, whether it’s finding truffles, lost persons, or cancer. It takes some of the mystery out of how dogs are able to perform the amazing detection work they do, but leaves much of the wonder we experience watching our canine partners at work.
