letting sleeping dogs lie

Not stirring trouble

Letting sleeping dogs lie means leaving a situation undisturbed to avoid stirring up trouble.

The image is literal—a sleeping dog poses no threat, but waking it might provoke aggression.

The phrase counsels against revisiting old conflicts or raising sensitive topics: I know he wronged you, but it was years ago—best to let sleeping dogs lie.
