After seeing a segment on 60 minutes almost a year ago I had the pleasure of finishing this book. This was a great book on the interaction and the necessity of military dogs in aiding the United States, not just during war but our daily lives. There were many sub stories in this book but the underlying theme of the book is TRUST. If the working dog trusts his handler than he will go to the ends of the earth to protect and fight for his handler. TRUST goes far in any relationship but is critical when you are dealing with lives.
