Frequently Asked Questions

How long are dogs pregnant?

The average canine gestation period is 63 days from ovulation, with a normal range of 58-68 days. Smaller breeds may have slightly shorter gestations, while larger breeds may carry longer. Our calculator provides an estimate based on standard veterinary guidelines.

How do I calculate my dog's due date?

Count 63 days from the date of ovulation (or 58-62 days from first mating). If you know both breeding dates, the due date is typically 63-65 days after the first mating or 63 days after the last mating. Use our calculator for an accurate estimate.
