Dog Pregnancy Due Date Calculator

-
estimated due date

Estimate when your dog is likely to whelp from the date she was bred. Canine pregnancy lasts about sixty three days on average measured from ovulation, though counting from the breeding date the range is roughly fifty seven to sixty five days because sperm can survive several days before fertilisation. This tool adds sixty three days to your chosen breeding date to project a due date and also shows an earliest and latest window so you can plan for whelping supplies and a calm space. It lists a few key milestones along the way, such as when abdominal swelling and nesting behaviour often appear. Litter timing varies, so treat the date as a guide and involve your vet for confirmation by ultrasound or x ray. Everything runs locally in your browser, and this is general information, not veterinary advice.

  1. Enter the breeding or mating date.
  2. Read the estimated whelping due date 63 days later.
  3. Review the week by week milestone timeline.
