The controversial story of one infamous breed of dog--a New York Times Bestseller ("Animals" list). When Bronwen Dickey brought her new dog home, she saw no traces of the infamous viciousness in her affectionate pit bull. Which made her wonder: How had the breed--beloved by Teddy Roosevelt and Helen Keller--come to be known as a brutal fighter? Dickey's search for answers takes her from nineteenth-century New York dogfighting pits to early twentieth-century movie sets, from the battlefields of Gettysburg to struggling urban neighborhoods. In this illuminating story of how a popular breed became demonized--and what role humans have played in the transformation--Dickey offers us an insightful view of Americans' relationship with their dogs.
