I believe the author’s theme to this book is survival. This idea is used throughout the book and is shown by the man presented by the author. The man goes to great lengths to attempt survival and he shows he is willing to survive through his outrageous idea of killing the dog and sticking his hands inside the dog. The man was very ignorant of the environment around him and took the weather too lightly at the beginning of the book but, as we soon come to realize is that he would go to great lengths to achieve survival.
