MWD's (Military War Dogs) have been around for as long as war itself and they've served and died right along side their two-legged handlers. They jump out of airplanes, sniff out bombs, can secure a prisoner with just one bite, and have been known to guard their fatally wounded handlers with their own bodies. *sniffs* In short, these dogs are made of awesome!
This book is filled with lots of good information about MWD's, including colorful photos and web links to find out more information. The only thing I would recommend is having tissues handy for the more sensitive parts.
