Dog Pregnancy Due Date Calculator

Due date and week-by-week milestones from the mating date.

Dogs are pregnant for about 63 days from ovulation. Because mating and ovulation rarely fall on the same day, 58–68 days from mating is normal. Ask your vet to confirm pregnancy by ultrasound.

Why the due date is a window, not a day

The 63 days are counted from ovulation, not mating. Sperm can survive in the female for several days and eggs need time to mature, so counted from the mating date a normal pregnancy lasts anywhere from about 58 to 68 days. If your dog was mated more than once, use the first date.

Signs labour is close

In the last week, take her rectal temperature twice a day. A drop below about 99°F (37.2°C) usually means puppies within 24 hours. Nesting, panting, restlessness and refusing food are also common. Read our full guide to dog pregnancy.
