My first Pup Kiwi was like this when we first got him, he would not go outside for anything!! It wasn't until he was about 10 months old (and it was warm again) did he start going outside. Once he figured out he could go outside and get praised and treats for it we committed to training him to go outside. We kept his peepad for the first few weeks but then took that away as well and he completely transitioned. I think every pup is different and its hard for them to want to go outside (especially if you live in new england and its freezing outside!) Good luck!
