The Polar Expedition Sledging Rations date from the 1900s to the 1910s, and consist of sealed tinned foods that were used in polar expedition sledging rations to feed humans and dogs during that time period. While these particular sledging rations are not known to be associated with a specific expedition, they are brands and packaging of rations that were used on Robert F. Scott's British Antarctic Expedition (1910-1913), as well as on other British polar expeditions between 1900 and 1920. The Bovril Pemmican was most commonly used as dog food, though human explorers ate it as well in emergency situations.
