I've just started reading a book called 'Horrie, the War Dog' by Roland Perry. It's about a little dog found found starving in the Lybian sand dunes. He was adopted by Jim Moody who was serving with an Australian battalion. He served duty by warning the platoon of incoming enemy planes. He heard them 2 minutes before a human could. When Horrie ran for cover, so did all the gunners. This is not a spoiler as this is printed on the back cover. It's after the war that the real fight begins for Horrie ...
