Dog Tales

Dogs have long been dependable companions by our sides. But it wasn’t always that way, and a look at their closest living relative, the wolf, makes it clear why. Research into dog domestication and intelligence offers clues into the human-dog relationship. And analyzing dogs’ brain activity and genes may even help answer whether dogs are in it for the food—or if they really love us.

PBS’ premier science series helps viewers of all ages explore the science behind the headlines. Along the way, NOVA programs demystify science and technology and highlight the people involved in scientific pursuits.
