That is what is really bothering me. I did rip out all the carpets downstairs, and that seemed to take care of the issue. I am guessing that the odor doesn't go into laminate flooring. However, I hate to spend that kind of money doing the second floor if I am trying to sell. The next house will have the carpeting ripped out immediately.
Yes, there is nothing that takes care of it. People don't understand. They are sure that she must be peeing and I miss it (no. She would be smelling the carpet. Besides, it is a wet dog smell not a urine smell.) I think the professional carpet cleaning made it WORSE.
