A must see show about dogs
Missed Part 1, but got to see Part 2 last night of “Dogs That Changed the World.” A very interesting special on PBS about the development of the domesticated dog from the wolf. Missed Part 1: “The Rise of the Dog,” but caught Part 2: “Dogs by Design.”
Your local PBS station may still air the second part this week, so check your listings:

Check out the weblink for the show. Lots of info and interactive fun. See snippets of the show and just how your snoozy pal is hardwired for action.
Nature: Dog
Just one very interesting finding is the correlation between coat color and the amount of adrenaline produced. Melanin (pigment cells) are chemically linked to adrenaline, the “fight or flight” hormone. As melanin development is delayed, so is the amount of adrenaline. This suggestion is based on a study with silver foxes. The study found, as the foxes became more domesticated through selective breeding for friendliness to humans, black and white patches appeared on their coat. Look for “Coat.” It’s the next to last slide.
