By my own admission, I'm no expert, but since I find dogs so habitual (once is cute, 2nd time, bad habit, as they say) if you're going to take them out, continue to do so, and not confuse them by also using pads indoors. Carry them to a preferred spot. (don't forget the "outie" treat afterwards)
My Cody was neutered at 7mo and only lifted his leg a teeny bit. The neighbor kids thought he was a sissy!
