How the date is worked out
Due date = breeding date + 63 days. Day 0 is the day of breeding, so a dog bred on Mar 1, 2027 is due on May 3, 2027, and births usually fall between Apr 28, 2027 and May 12, 2027. If the dog was bred on several days, count from the first breeding and expect the window to run to the last breeding + 72 days.
Good to know
Counted from a single breeding date the range is wide, 58 to 72 days, because the day of ovulation isn’t known. Counted from ovulation (found with progesterone tests at your vet) it is 62 to 64 days (Merck Veterinary Manual).

Frequently asked questions
How long is a dog pregnant?
About 63 days on average, counted from the breeding date; most births fall between day 58 and day 72.
How do I calculate a dog due date?
Add 63 days to the breeding date. Example: bred on Mar 1, 2027, due on May 3, 2027. The calculator above does it for any date and lists the milestones.
What if the dog goes past the due date?
Most births fall by day 72 after breeding. If that day passes, or anything about the mother worries you, call your veterinarian.
Can I use a different length for my breed?
Yes. Change the length (in days) in the calculator; the date, the window and the milestones move with it. The Android app keeps the length for each animal or batch you save.
Where the numbers come from
Sources: Merck Veterinary Manual: Approximate Gestation Periods. Breeds and individual animals differ; change the length in the calculator if yours usually runs early or late. These dates are estimates, not veterinary advice: ask your veterinarian about your animal.
