yorkie due date

Question
I have a 3 year old yorkie who mated with my 21/2 male March 19, 21, 24, & 27th.  I am worried sick about her due date.  I am a new breeder and was trying my best to be a good mother.  My grandchildren let them out to play & this is what happened.  I know they mated because my daughter called me last night to tell me after they got home.  Please tell me how to judge Dixie's due date. I will be carrying her to the shop with me after today. Every day.
Thank you so much for helping me.

Answer
Hi Gloria

If I understand she was mated on "purpose" on the 19 - 24th and on the 27th it was an accident.

If I'm right about that, then I would expect pups the week of May 24th.  The thing is this, if you didn't do progesterone testing but did it by counting days, you could be off by a few days. Semen lives for 24 hours and eggs take 7 days to mature.

Good luck
