Normal canine gestation ranges from 58-68 days. Consult your veterinarian for prenatal care and to confirm pregnancy.

Dog pregnancy duration

The average canine gestation period is approximately 63 days (about 9 weeks) from the date of breeding. However, the actual due date can vary based on when ovulation occurred.

Calculating the due date

Starting pointGestation period
Breeding date~63 days
Ovulation date~65 days

The difference exists because sperm can survive in the female reproductive tract for several days, and ovulation doesn't always coincide with breeding.

Normal gestation range

Puppies can safely be born anywhere from 58 to 68 days after breeding. Factors affecting timing include:

  • Breed size (smaller breeds may whelp slightly earlier)
  • Litter size
  • Individual variation
  • Accuracy of breeding date
