Thank you everyone.

My ultimate goal is to have them want to go potty outside, but just in case I don't see their cues to go potty or on rainy/snowy days, I would like to keep a puppy pad down for them. Right now I have the pad by the front door (can't get any closer)

and it's just the 1 pad. And that is the door that I would have them use to go outside. I am also going to try it when it starts to warm up because right now in central Missouri, we still have snow and ice on the ground and more to come.
