She's the author of "Inside of a Dog," which if you haven't read yet - DO SO. I read it 3x in a row when I first got it. It's an awesome book.
Anyway, here's a 3 part interview with her. The first video is about how dogs see, the next is about how they smell and the last is about how they hear. It's only about 20 minutes total.
