Kacee is fully house trained and was by around 4 months of age. I've said before that she had a couple of accidents after she was spayed, but I think that was just from the surgery. She hasn't since that time and she was 6.5 mos old then. I trained her to go either outside or in the attached garage on pads. She always rings her bells. Never, ever has accidents. I still give her treats afterwards, too. She expects them and she's worth it, because she tries so hard to be good.
