Neither our Bruce, who we lost at christmas , or Bruin our new 3yo buddy are hearing any of this. Through winter neither would bother going out in the evening except right after their supper, 6,30 pm ish. Not scared of the dark, just prefer the sofa. If the weather was less than nice our Bruce would often not go out even after breakfast. He would drink noticably less to avoid having to go outside if weather particularly mucky. More than happy to go to the woods etc.
Turns out our chaps easily have 14hour bladders tho we obviously don't rely on this and encourage them to go more often. Bless them.
