A dog pregnancy lasts about 63 days from the breeding date, which is 9 weeks; most births fall between day 58 and day 72. Day 0 is the breeding date, so week 1 is days 0 to 6, week 2 is days 7 to 13, and so on.

Week by week: days and dates
Dates for a dog bred on Mar 1, 2027. Pick your own breeding date in the calculator above.
Day 0 is the breeding date. If she was bred on several days, the calculator counts from the first breeding and the usual window runs to the last breeding + 72 days.
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).
Weeks 2 to 4 (days 7–27)
Nothing on the schedule until day 31 (halfway, week 5). By day 27, 36 days are left to the due date.
Week 5 (days 28–34): halfway
Day 31 (Apr 1, 2027) is halfway through a 63-day pregnancy. From here, 32 days are left to the due date.
Weeks 6 to 8 (days 35–55)
Nothing on the schedule until day 56 (a week to go, week 9). By day 55, 8 days are left to the due date.
Week 9 (days 56–62): a week to go and the usual window opens
Day 56 (Apr 26, 2027) is one week before the due date. The schedule’s reminder for this day: get a clean, quiet birthing area ready.
Day 58 (Apr 28, 2027) is the earliest usual date: from here on, a birth is inside the usual range.
Week 10 (days 63–69): the due date
Day 63 (May 3, 2027) is the due date, the average length counted from breeding. It is an estimate; most births fall between day 58 and day 72.
Week 11 (days 70–72): the usual window closes
Day 72 (May 12, 2027) is the latest usual date. If that day passes, or anything about the mother worries you, call your veterinarian.
Frequently asked questions
How far along is my dog?
Count the days since the breeding date (the first one, if she was bred more than once). Days 0 to 6 are week 1, days 7 to 13 are week 2, and so on: day 31 is in week 5 and the due date, day 63, is in week 10. The calculator above counts it for you.
How many weeks is a dog pregnant?
About 63 days, which is 9 weeks. Most births fall between day 58 (week 9) and day 72 (week 11).
When should the birthing area be ready?
The schedule marks day 56 (week 9), one week before the due date: get a clean, quiet birthing area ready. For a dog bred on Mar 1, 2027, that is Apr 26, 2027.
