If she is having problems with house training, I would recommend going back to the basics and treat her like she is a new puppy. When you can't watch her, gate her in a secure area or crate her. If it's just beds she has a problem with, clean them with something to get rid of the odor (to the dog), vinegar & water works to get rid of the ammonia smell and close the doors. If she doesn't have access to the bed, she can't pee on it.
