Dog Pregnancy Calculator

Calculate your dog's due date (about 63 days from breeding) with a week-by-week timeline of what to expect.

Breeding / mating date

How to use it

Pick the first mating date.
Due date range is 58-68 days later; ovulation timing by your vet narrows it.

How it works

Canine gestation averages 63 days from ovulation, with normal whelping 58-68 days after breeding because sperm can survive several days. Ultrasound can confirm pregnancy from about day 25; X-ray counts puppies after day 45.
