I've had a couple dogs...always got them potty trained easy, then they go to the bathroom on the carpet, rub their nose in it and give them a spank (don't need to beat them) then take them right outside...has worked everytime, my dog of 5 years has only went to the bathroom once since she was house broken, I was gone for 16 hours..and she went on the tile by the front door, when you take them outside to go make sure you praise him/her with a treat and good boy/good girl
