Pregnancy calculator for Dogs

Answers the question: When is the birth date for my pregnant dog?

Pregnancy in dogs normally lasts 63 to 67 days (about two months or nine weeks), but can be as quick as 58 days and as long as 68 days. This pregnancy calculator for dogs will calculate the most likely birth date using the mating date as a starting point.


Most likely birth date: May 25
Earliest birth date: May 20
Latest birth dates: May 30

Remember that these dates are estimates and that an incorrectly entered mating date can significantly affect the estimates.
