To “go whole hog” is a common expression meaning “to go the entire way” or “to the greatest extent” as far as something particular is concerned. Its origins, however, referred to eating and using the entirety of a slaughtered pig. As my dad used to say, “Use every part but the squeal”. Most people don’t eat every part of any animal, but some of us eat parts we usually wouldn’t care to if we actually knew the content of the prepared foods we eat. The most obvious is intestines used as the casing for sausage.
