Dog pregnancy calculator

Dogs are pregnant for about 63 days from ovulation — but the window from a breeding date is wider than most owners expect. Enter the date you know and get the due-date range plus a milestone timeline. Sources on the methodology page.

Estimates from published veterinary ranges, not a diagnosis. Only a vet can confirm pregnancy and monitor it safely — and labor problems (30+ minutes of hard straining, 2+ hours between puppies) are emergencies.
