When I first got Rocky he would wake up once in the night to tinkle. It was cold out there at 4 in the morn even in S. Calif. Anyway, I read about putting the pup in the tub with pee pads. I use news paper which not only works GREAT for me but it is free. I feel I'm recycling

Yea, anyway the tub works great too because he can't get out! He would go right away when I told him to tinkle.
So you might want to try the tub thing
