Here's how to view sleeping dogs.

That's fine. People will pick foods that are healthy for them like vegans for example eat totally different than someone who isn't. 

Just curious---where do the sleeping dogs come in? (*grin*) If the 'sleeping dogs' are bad habits, leave them alone while they're asleep. It's only when they wake up that they're a problem.

I guess I see it as the little old habits that seem to be asleep until we face a challenge or a trigger that wakes them up and poke their little heads into our minds.  They lay sleeping until they are woken up.
