I agree with capt_noonie 12 weeks old is way to young to expect baby to be 100% pad trained. Limit his space. My now passed pups were 100% pad trained by 5 months, and completely house broken at 7 months. I kept wee-wee pads in 2 places when my babies were wee little pups, one was in their confined area. The other was in the living room. They were allowed in that room ONLY if I was there. If they had an accident I would blot up the pee with the pad, put the pad back where it belonged, pick up the pup, place her on the pad and tell her, "pee-pee" on the pad. NO punishment, if you do not have a small area to confine him in I suggest an x-pen with his bed, food, water toys and pee pad when you cannot supervise him. He SHOULD NOT have the run of the house at 12 weeks old. Like capt_noonie suggested, close all doors that lead to other rooms, keep him confined to an area where you can watch him.
