answer:Sometimes just washing the rug or mopping with the usual cleaner is not enough to remove all of the odor. It’s good enough for our noses, but not the dog’s. I have found using some of the odor eliminators from pet supply stores work as well as bleach, if you are able to use it without damage to the floor. Also, once the dog knows that a particular spot is a bathroom spot, they will continue to use it as a bathroom spot. If you are willing to let her use it, then perhaps placing some puppy training pads will make clean up easier.
