The "Dogs of War", Belgian war dogs haul heavy equipment into battle
One of  the most interesting sidelights of the war is the use of large dogs to draw the Belgian guns.  This photo shows the dogs tired after a stiff march hauling the guns.  This photo in the newspapers of the time created the phrase, the "Dogs of War."
