Go to the Dogs
Meaning: To be ruined; to get into a bad situation from which recovery is all but impossible
Origins & History: From the time of the ancient Greeks and Romans, food deemed no longer fit for human consumption might well “go to the dogs” or be ” thrown to the dogs,” because the dogs – if they were hungry enough – would ignore the smell and taste and eat it anyway.
