Parents need to know that this story has moved kids for years. Its fast-paced drama hooks even reluctant readers. That said, it also reflects the sensibilities of another age. This is a story of survival, which entails a great deal of brutality by and toward dogs. It may be a bit much for sensitive young animal lovers of today, when beating dogs with clubs is not considered an acceptable way of training them. Dogs fight each other to the death, and tear out the throats of dogs and men, yielding geysers of blood when the jugular is ripped open. Buck, the canine main character, is often beaten, once almost to death. But ultimately, this is a story of dignity and leadership that will grip kids and hold them.
