I'm not super experienced in this....but I'll share what I've done with my experiences.
I think the breeding is as individual with what breed, as it is with each individual dog.
I keep track of ALL of my girls cycles, whether I'm breeding them or not. I mark down when I notice first swelling, first sign of discharge, when they are getting flirty with the boys (not that they are out with them at this time, but more of a teasing thing briefly), when they are no longer interested, and when they are completely finished . ALL of this gets marked down in a note book.
All of my girls have been bred when they are standing. With mine, they have never been standing before day 10. I also breed a day, miss a day, breed a day, and so on (I have been told that unless you have shipped semen to skip a day to allow the semen to 'rejuvenate'....if you breed every day, the quality of the semen drops significantly). BUT 2 of my girls that I've bred stood for a FULL WEEK! So, they were bred 4 times over a week....one resulted in 10 puppies, the other in 1! I start taking temperature at day 60 from the FIRST breeding as well, but because my first 2 were bred over a week, I don't know exactly when they took! Both girls needed c-sections, the first because her uterus ruptured after the first puppy was breech and stuck, the other because the singleton was too big for her to whelp naturally. (Both of these dogs were related too, not that it matters, but they were mother and daughter)
I just recently bred another dog, also a daughter and sister to the above 2 dogs. She has also never come to standing heat before day 10. Every cycle, she hits day 10, stands for 3 days, and is out by day 14. I drove a distance to breed her, got there on a Tues and said, she will be one day early on Wednesday, standing for sure on Friday, and out by Monday. Sure enough, Wednesday she was interested, but not standing....we AI'd her because we did not have the male on site and the owners had driven to meet us (and I knew it was a short window to breed her). Friday she was standing, and by Sunday she was already starting to not be interested......and at week 6 right now, she is looking like she took!
