Calculating Due Date

Do the majority of you that do AI's count 63 days starting the day your bitch ovulates (which is usually the day before the first breeding) or from the date of the first insemination. Do you include the day the bitch ovulates as day 1?

The ovulation is usually 2 days before the 1st or only breeding to my knowlege. You can count from there or from the LH surge.

Re: Calculating Due Date

Count 63 days (9 weeks) from the day the progesterone is 5.0 puppies usually arive 24-48 hours on either side of this day.....mine usually on the earlier side.

Re: Calculating Due Date

I use the calendar on the debbiejensen.com website, and usually plan for a few days early if the bitch seems to have a large litter.
