How common is it for pregnant dogs to go into labor before Day 63? Only one mating took place and it was on the 11th or 12th day of the female’s cycle. Ultrasound was done on day 35. X-ray was done on day 50, today.

An average pregnancy lasts 63 to 65 days. Dogs can give birth any time from the 58th day to the 68th day. Any birth during that time frame is normal. Earlier than 58 days and your dog may be giving birth to premature puppies.
