If it works for you, it works! I don't think Jackson could ever be pad trained, even as a pup, he wasn't into it. He needs lots of space to sniff and move first, but wow it definitely would've been nice on some days we've had recently with below freezing temps. So if he's already being successful at it, I'd say go for it. I usually prefer outdoor training simply because I find a lot of pad trained dogs will always have accidents throughout their life rugs and carpets etc but I'm all for it if you can do it and be successful.
