first of all, does she have a way to get down and someplace else to go when she can't hold it ?

secondly, make a padded place for her as far from you as possible, by putting down a kitchen garbage bag or other plastic, and putting towels or other old cloth over that. if you think it's scent-related, rub the cloth in your hair (or under your arms) to let her know what you are trying to teach her.

poor baby might just be so distressed by your distress that she isn't able to do what's right. but life is hard enough without the added stress of washing bedding every morning... i hear there are doggie diapers, too, (maybe you could make your own).

what a terrible connumdrum, love vs despair~
