let sleeping dogs lie

Don't provoke problems

Let sleeping dogs lie advises against stirring up trouble by revisiting old conflicts or raising sensitive matters that have settled down.

The metaphor suggests that a resting dog might bite if disturbed: I thought about asking why he quit, but decided to let sleeping dogs lie.

The saying favors strategic inaction over unnecessary provocation.
