Canine combat vets suffer, too.

(A bomb-sniffing dog at Camp Leatherneck gets a little morning exercise)
The Wall Street Journal has this illuminating story on the trials and tribulations of bomb-sniffing dogs in Afghanistan.
I had my own experience with a British bomb-sniffing spaniel named Sonny in Helmand Province. Sonny accompanied a group of Brits and Yanks from Minnesota on a convoy.
He was particularly touchy if people approached him. Word from his handler was that if Sonny (it may have been Sunny but that would have been worse) took a nip out of one more person his military career was kaput. Sonny snarled at me as I walked past.
During the convoy, an IED went off in front of the truck I was in. The gunner in my vehicle, Sgt. Pat Rix, from Duluth, saw something flipping over in the air from the explosion and was sure it was Sonny the Bomb-Sniffing Dog taking one for the team. It turns out it was just a blade from a mine detection vehicle.
Sonny had been spared.
No word a the end of the convoy whether Sonny had stayed squared away.
