if she does not get pregnant about day 25 to 27 she should be returning to normal, if she gets pregnant, her vulva and tits will stay slightly swollen if I remember correctly. someone correct me if I am wrong.. but this is chanel second heat and I think I remember me bringing Harry home from my mom's at day 26 of her first heat.I had it marked in the calendar..LOL I missed my boy so much, but I did not want to risk her pregnant so young. and I remember giving her a bath before he got home to get rid of the odor and she looked almost normal to me..
