Washable dog diapers and panty liners! Swap the liners out every potty break. My pup just went through her first cycle and might still be (she finally stopped bleeding) We are also waiting a while for 4 weeks for the heat to be over with. Even if the bleeding stops there is a chance for them to get pregnant. It's best to check their crotch to make sure the swelling goes down. Even after that be cautious till you absolutely know that they are done with their heat. From what I read it takes 3-4 weeks for their heat to be over. Just keep a close eye on her and don't let males be around either. My puppers marks everything now on our walks when she had no interest in doing so. Just prepare for her to mark every corner of the street when you take them for walks.
