In dogs, a typical pregnancy averages 63 days; delivery can occur anywhere between 58 and 72 days, though. If you have confirmed your dog’s pregnancy with a veterinarian and she has gone past day 63, there is not necessarily any reason to be concerned. First-time mothers, older mothers or small litters may slow the whelping process. However, should the pregnancy go past 70 days, something may be wrong and you should consult your veterinarian.

Checking the Due Date

Often, late whelping is the result of miscalculated due dates. Blood progesterone levels can help the veterinarian determine the stage of pregnancy.

Pregnancy Complications

Dystocia refers to abnormal or difficult births. With late whelping, dystocia causes can be maternal or fetal in nature. Small pelvic size, a small birth canal or uterine inertia can disrupt the start of the whelping process. Uterine inertia is the absence of uterine contractions. Improper fetal position or single puppy pregnancies are other possible reasons for delayed whelping.

Intervention

If your pregnant dog has gone 70 days without showing signs of whelping, consult a veterinarian. Dystocia complications may require medical intervention, such as contraction stimulation with drugs such as oxytocin or calcium, manual fetal manipulation or a Caesarean section in order to reduce any risk to the mother or pups.
