Sheila was a dog who received the Dickin Medal in 1945 from the People's Dispensary for Sick Animals for bravery in service during the Second World War. She is the first non-military dog to have received the medal, which was later sold at auction alongside the medals of her owner, John Dagg, for £25,300 by Sotheby's.
