I've mentioned before, I think, that I'm a nerd for working dogs.
I'm fascinated by dogs performing work duties, be it something they were bred for (Border Collies herding sheep), or something they were taught to do (Dobermans as Service Dogs). A dog performing work that he or she loves is a beautiful thing to watch, and a good dog-human partnership is a well-oiled machine.
Military Working Dogs fall into this category, of course. In fact, there are around 2, 300 dogs currently deployed by the U.S. Military to perform a number of tasks with our troops.
