My husband places towels down after the dog pees on the floor. Doesn't this just teach the dog to do it again? Our 4 year old dog gets up in the middle of the night and pees on the carpet. I usually try to immediately clean it with an enzyme cleaner and soak up as much as I can with a towel. My husband sprays the area and then just leaves a towel over the spot. I am convinced this just tells the dog that it is ok - the same idea as using a piddle pad.
