How often do they go outside?

I would remove the puppy pads completely and take them both out to toilet every half an hour, and praise once they do it outside, and completely ignore them if they do it inside (unless you catch them in the act, do a quick "ah-ah" sound and put outside and praise when they toilet outside).
