He usually goes to the bathroom in the house in the middle of the night. Once and awhile he will go in the day time. He doesn't do that everyday though. He also went in my aunts house. I always give him treats when he goes to the bathroom in the yard or out on walks. I don't give him treats when he goes in the house. When ever we catch him "going" in the house, we tell him "NO!" I thought that would be good.
