You are doing great! It is super hard to keep a male from a female in heat, especially in the same house. I would let Scooter go stay with someone else if you had someone you trust. It would just be so much easier. I can't remember about the bleeding, I've only had one female dog to come into heat. I don't think you have much longer though. Is she wearing just diapers or are you putting bloomers/dog panties over them? I did this with my female and it really helped keep them on. Good luck!!!
