"It would perhaps not be amiss to point out that he had always tried to be a good dog. He had tried to do all the things his MAN and his WOMAN, and most of all his BOY, had asked or expected of him. He would have died for them, if that had been required. He had never wanted to kill anybody. He had been struck by something, possibly destiny, or fate, or only a degenerative nerve disease called rabies. Free will was not a factor." - Cujo, Stephen King.

This part absolutely wiped me out the first time I read it. King did an excellent job of putting us into Cujo's mind, allowing us to understand the dog's innocence.I remembered being saddened at the idea that Cujo could not comprehend why he was doing the things he did.
