I did both and I still keep a pad on our back screen back porch, because we have some pretty bad storms from time to time in Florida , where I can't let the dogs out. Ike is doing fine with it, he would rather go outside and now ask to go out. I started out with the pads and still took him out, and gradually he started doing his business outside. I used the word potty to train him on both and he knows what it means, of course a little treat when he did.
