How were dogs used in the war effort of WWI?
There were many dogs used in WWI. They were used for different reasons and all had their own jobs to do. Sentry dogs were always assigned with one guard. Their job was to alert when enemies were near by barking and growling. Scout Dogs instead of barking or growling , they were taught to be silent so they wouldn't give up their position. So instead they stiffened their tails or sent some type of signal. Casualty dogs were used to aid people they were practically dog nurses they found dead and or wounded soldiers and tend to their wounds , they carried little first aid kits and ace bandages.
