This handy little script will calculate a due date based on the date of your first breeding
and the standard of a 63 day gestation period.
Date of first breeding:        
                                          (MM/DD/YYYY format)

Estimated Due Date: 

Note* Puppies are usually born 61 days after conception. It takes 48 hours for the egg to ripen before the egg will allow penetration of sperm. If your female ovulates on day 11 of her cycle, than conception began on day 13 of her cycle. Not knowing exactly when ovulation occurs, this chart is as close as you can get to predicting her due date.

There are many factors that determine due date

1. first timers whelp later

2. large litters whelp earlier
