In the book Woodsong by Gary Paulsen, the characters focused on are the animals. Paulsen has many dogs as he is going to and does run the Alaskan sled dog race, the Iditarod. Scarface is not one of Paulsen's dogs, but comes into Paulsen's dogs' area anyway. Because he is a feral or wild dog, Scarface could injure or kill Paulsen or even one of his sled dogs. Because good sled dogs are trained for their position in the line, the race itself, and for the master they run for, the animals are worth a great deal both in time and money. Scarface could injure one of Paulsen's dogs or even kill one, which Paulsen could ill afford. He therefore thinks about killing Scarface before any injuries can occur but decides against that drastic measure.
