This book may be too much for young or sensitive readers.  This book does have some mention of coon killing, accidental death, and sadness at the end.  While it is a classic, adventurous book about a boy and his dogs, very sensitive children may not enjoy.  It also has a few 'choice' words.  I have listed some of the pages in which, you as a parent, may want to look into and decide if this book is right for your child.   
pages:  26-language,  73-74 event, 165-language & event, 167 event
This class will by no means mention any inappropriate language or DETAILED references to sensitive events.  

Although the character in this book stops occasionally and prays or wonders if God has helped him in some way, there is nothing taught on the topic of religion in this class.
