Shih-tzu in heat and I was wondering when I should take her to t he stud

Question
I have a shih-tzu female and she is in her heat cycle now, and I would like to know when the best time to take her to the male would be. She hasn't started bleeding as of yet, but is it better to take her before that happens or during?
Thank You for your help I really appreciate it.

Answer
Hi Kate! You said she's in her heat cycle, but she's not bleeding. What do you mena then?:-) Most breeders try to breed on days 11 and 13, or on days 12 and 14 of the heat cycle. They start day one on the first day of bleeding. This is usually when the female is ready to be bred, and will allow the male to do his buisness. When she starts to flag, move her tail to the side, and stand, then it's time to take her. Her bleeding will lighten in color, and her vulva will soften up some. These are all signs that she's good to go. If I can help with anything else, let me know!
