The photo to the left shows working dog Rronnie with his handler. The use of dogs in warfare goes back to ancient times, even as far back as the Greeks, and the Egyptians.
During World War I, the Belgians used their Bouviers des Flandres to haul machine guns to the front. In World War II, dogs were used to warn of ambushes and to detect arms caches.
