One often overlooked war dog role was use as a draft animal. During the First World War, Italy and Belgium were two of the countries that used to pull small, two-wheeled carts full of machine-gun ammunition or other supplies. Often these dogs had often been used to pull milk carts so were used to hauling loads. Draft dogs were also popular with the German Gebirgsjaeger (mountain troops) in WWI, who utilized them to pull carts or sleds in rough, mountainous country. Some military dogs even pulled small vehicles packed with arms, equipment, supplies, and food. Sometimes they transported soldiers too, both wounded and whole.
