HELP PLEASE!!!

Are you referring to part one of the book? 

i honetly  dont know im probably gonna go with part 1

As Bill and Henry travel through the frozen, snow covered territory they notice the wolves following a little closer every day. Building fires at night to keep warm and to keep the wolves at bay, the men sense the animals closing in slowly but surely every day and every night. The wolves did not stop closing in and begin to kill the pack dogs. The next morning as Bill is feeding the dogs he notices the wolf (a she-wolf) amidst the sled dogs and is able to land a blow with a club. The following morning the men find another sled dog, Frog, gone. Unlike Fatty, the first dog to disappear, Frog was "no fool dog" and also the "strongest of the bunch." Finally the men are not able to keep a large enough fire going and the wolves kill Bill.
