What it's like to be a puppy

Between housetraining and playtime, the first year of a puppy’s life is also marked by a burgeoning personality. Alexandra Horowitz, senior research fellow and head of the Dog Cognition Lab at Barnard College, Columbia University, joins host Krys Boyd to discuss her observations of her own puppy, Quid, and the major milestones dogs make in the first year of their lives. Her book is “The Year of the Puppy: How Dogs Become Themselves.”
