If he's not ill or hurting, he could be expressing frustration over something in his life - a new dog in the neighborhood he can smell and hear, an occasional sound that worries/confuses him, a boring life with little work to do, something/someone added to his life causing stress. If you Google the reason housebroken dogs suddenly begin marking in the house, you'll see there are many reason dogs urinate or defecate other than to cleanse the body of waste. They are often sending you messages by the marking behavior that there is a stressor in their life they don't know how to handle.
