I dunno, damp, a lot of the time a bladder infection means you get little or no warning that you've "gotta go right NOW", and a dog doesn't have the understanding that a person does. I'd certainly interrupt a dog in the act and make it clear that it wasn't acceptable, but I don't really see how going over the housetraining (i.e. by leashing the dog and taking it out on a schedule) is a bad idea, it's not "excusing" the bad behaviour, it's retraining the desired behaviour.
