Some say 6 weeks after they blow their coat. Now is that 6 weeks from the beginning or 6 weeks from when they are done? I have no idea. My female didnt do that. She was shedding in Sept and finally was ready to breed in late November. Humm, just was thinking. Maybe it is 6 wks after they are done, now I will have to go pull the calendar out again. Are you actually checking her vulva?? or just looking for drops on the floor? When Yoko started, it was so light, it just dried before it went anywhere. And then she cleaned herself and you wouldnt know it was there unless you were looking for it every day. Best time to check her is right after a walk, but before she has a chance to clean herself. You may also notice her more interested in smelling her own urine, as it will change in scent.
