All I can say is: Wow, that is pretty twisted. 
 And from what I understand, it will only get worse. 
 The whole concept of psychological warfare on this level is diabolical and completely mind-boggling. But the dogs? That left me utterly speechless. 
 For what it's worth, I saw the movie first. And it's an excellent movie. I was impressed with what little they needed to change to switch the book from first person POV to the necessary third person POV for the movie. But the impact is so much greater from the book. 
 Can't wait to read the next book.
