How long are dogs pregnant?
Dog gestation averages 63 days (about 9 weeks) from conception, though it can range from 58–68 days. Because sperm can survive a few days, counting from the breeding date is an estimate. Your vet can confirm pregnancy and timing with ultrasound (around day 25) or X-ray (after day 45, which also counts puppies).
Watch for a temperature drop below 100°F, which usually signals labor within 24 hours.
