my bitch never used to tie right until the end of her season, she like yours would stand and move tail but still it didnt happen till the end . and i mean the end, i always think i missed it as she was always at the end of 3 weeks. i had a stud her with me from the 6 day and he stayed for two hole weeks and still nearly missed it as they only tied the day before he was due to be picked up hope this helps
