My pup has recently gone through her first season at the age of 9 months
I noticed as she ran ahead of me that there was something there that wasn't normally
When we arrived home I bathed her and saw that it was her vulva that was swollen
a couple of days later she started to bleed, not much but enough to periodically wipe the area with a baby wipe. This lasted just over a week and then we were careful where we would take her out
The only issue I have is that her nipples are still prominent , but I'm told this is normal
