puppies image by Bobi from Fotolia.com. The period of pregnancy in dogs is called gestation. During gestation the puppies develop in the mother's uterus. Average gestation in dogs lasts approximately nine weeks, or 63 days. However, puppies can be born as early as 58 days or as late as 68 days.nlike humans, pregnancy in dogs cannot be confirmed with a urine or blood test. Instead, veterinarians rely on feeling a dog's abdomen 26 to 35 days after breeding for signs. However, this proves only 85 percent accurate. Owners may need to wait 45 days after breeding to see true confirmation on an X-ray.
