Our dog (Petit Basset Griffon Vendeen)is 15 now and showing his age. He is left quite a lot during the day and doesn't make a mess, and is clean at night, but quite often in the evenings and mornings when we are all at home he simply wees in the hallway - and on occasions poos too - he does know how to ask to go out and barks loudly to let us know where he wants to be, any ideas why he has started to do this? Poor chap is more or less blind and quite deaf, which doesn't help, but quite sprightly and enjoys his walks still.
