表現ごとの解説

Let's just leave well enough alone. 口調とニュアンス: Gentle and friendly

Use it when a situation is fine now and you think changing it could make it worse. It's less useful when there is a real problem that needs fixing.

“Let's just leave well enough alone.”

使用作品：All of My Heart: Inn Love (2017)
Let's let sleeping dogs lie. 口調とニュアンス: Calm and wise

Use it when an old problem or argument is quiet and talking about it again would wake it up. Don't use it to hide something serious that people need to know about.

“Let's let sleeping dogs lie.”

使用作品：Blue Jasmine (2013)
Why open a can of worms? 口調とニュアンス: Serious warning

Use it when one question or action could start many new problems at the same time. It sounds like a warning, so it's stronger than the first two lines.

“Why open a can of worms?”

使用作品：Hollywood Ending (2002)
Let it go. 口調とニュアンス: Short and kind

Use it when someone keeps thinking about an old problem that doesn't matter anymore. With a stranger or in an angry moment, it can sound a little rude.
It's water under the bridge. 口調とニュアンス: Relaxed and forgiving

Use it to say that an old problem is in the past and you're not upset about it now. It's often an answer to an apology.
Don't rock the boat. 口調とニュアンス: Careful, a bit cautious

Use it when a group is calm and someone wants to say or do something that could upset people. It can sound like you're telling the person to stay quiet, so use it carefully.

よくある間違い

惜しい表現 ~~Let sleeping dogs lying.~~

より適切な表現 Let sleeping dogs lie.

After let, use the base form of the verb with no -ing and no to. Compare "Let me help" and "Let it go."
惜しい表現 ~~Let sleeping dogs lay.~~

より適切な表現 Let sleeping dogs lie.

Here lie means to rest without moving. Lay needs an object, as in "lay the book on the table," so it doesn't fit this idiom.
惜しい表現 ~~Let's just leave good enough alone.~~

より適切な表現 Let's just leave well enough alone.

The fixed phrase uses well, not good. People will understand the wrong form, but it sounds unnatural.
