This 2-part series by PBS isn't Pit Bull specific, but discusses current theories about the 15,000 co-evolution of dogs and man from the domestication of the wolf up to the emergence of the hundreds of modern dog breeds.

However, they do illuminate the many misconceptions about canine behavior (and misbehavior) and posit it as a result of a major disconnect between the modern man, who for the most part seems to want an instantly obedient warm and furry housepet with little or no effort on their part, and modern dogs, many of which have been bred for hundreds or thousands of years for very specific tasks. I found it fascinating and have watched it several times.
