Hi and welcome !
I disagree with this : "The more times they tie, the better our chances, right? "
As far as my experience and most of breeders i know including most breeders here on Yorkie Talk you get better results breeding every other day. For an example: supervised breeding on day 11th, 13th and 15th. Put them together, assist with the tie to make sure the stud does not get hurt. Then after they separate, separate them and keep them away until the next scheduled "visit".
Some others here will hold the female after the tie. I dont do it . I also do not hold the female if she is not ready as my girls will stand if they are ready . But that is my experience and i respect others.
XOXO
