This month, the PBS program NOVA features a great documentary called "Dog Tales," which explores the relationship between humans and canines. It attempts to answer the question "are dogs domesticated because they love us or because we feed them?" In Keith's case, I already know the answer...
The program is wonderful and worth watching. You can view it here (see below). It's also available via various streaming devices (Roku, Apple, etc.).
From PBS/NOVA:
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.
