Hi all my girl is on day7 of her season yesterday on day6 she started to flag, but only in the morning and at tea time, the rest of the time nothing.
When theother girls go hear her nothing.Her vulva is swelling but not as big as it should be.
I am hoping to mate her sometime next week. Have all the tests done for my breed.
She has been mated on days12/13 no problem & each season follows the same pattern. Always starts flagging on day8.
I am taking her to vets on day10 to be swabed but i am a bit worried has she never has flagged os early on.

My girls start flagging quite early in their seasons, and even humps their friends, but if a dog approached before she was ready she wouldn't let them anywhere near, so I wouldn't take that as her being ready just yet, hopefully the tests should let you know.

Good luck.
