The best thing that worked for me and it took me until teddy was 6months to finally do it was crate training. I would leavve him in there with the door closed whenever he was unattended and as soon as i would take him out I would immediately put him on the pad. While i was at work i would keep him in his pen with a pee pad in there and if i got home and he had pooed or peed on the floor i would show him the pee say no and put him on the pad and then praise him. THis is kind of gross but i even put the poo on the pad and said good boy. Soon enough he got it! good luck and dont worry eventually he himself will get disgusted by his own pee and will WANT to go onthe pad!
