We have a 17 year old siberian husky who suffers occassionally from incontinence. She won't go on newspaper but she will go on an old towel laid out for her. I keep a piece of extra linoleum under the towel to protect the wood floors. This gives her a safe place where, if she can't hold it until we get home or if she can't wake us up at night to take her out, that she can go and not get in trouble and makes it somewhat easy to clean up. I think this actually helps reduce the stress of potty training for the dog and their humans.
