Understanding your result

If your dog was mated on a known date, this calculator tells you which day and week of pregnancy she is in today, and how many days remain until about day 63. A dog mated on 1 October 2026 is on day 17, in week 3, on 18 October 2026.

Dog pregnancy is about 63 days from ovulation, and from mating births usually happen between day 58 and day 68 because sperm can survive several days and ovulation timing varies. The calculator shows the expected date and the latest normal date.

Ask your vet to confirm the pregnancy, usually by ultrasound, and to plan the whelping. Call straight away if there are no puppies by the latest normal date or if she strains for 30 to 60 minutes without producing one.

Common mistakes

Counting from the wrong date, such as the date the female came into season.
Treating day 63 as an exact due date.
Waiting past the latest normal date before calling the vet.
Changing her food without vet advice.
Not having the vet's emergency number ready.

Good to know

Pregnant dogs have different feeding needs; ask your vet rather than using a standard food calculator.
The Dog Pregnancy Due Date Calculator gives the due window for different date types.
Prepare a quiet whelping space and keep your vet's out-of-hours number handy.

When to talk to your vet
