The kennels at Lackland Air Force Base raise about 100 dogs for military duty, mostly because of the animals' terrific sense of
smell. There's talk about expanding the use of military dogs to make them available to ordinary combat patrols.
These days, while the demand for working dogs is so high that the Department of Homeland Security recently put out a call to civilians for viable canine candidates, war dogs are usually bred and trained by the military or private contractors . . .

These are beautiful animals who deserve better than to be caught up in human stupidity. Yes, I'm aware of the argument that it's better that a dog die than a human, but humans at least give tacit consent to their involvement in warfare. The dog doesn't know any better - it does what it's trained to do.
