The gestation or pregnancy period in dogs begins from the first breeding session or fertilization until the birth of the puppies. Though the period may vary as per the size or breed of the dog, usually, the gestation for small dogs as well as big dogs lasts for about 60 to 63 days, or 9 weeks. Female dogs have menstrual cycles throughout their lives and are capable of reproducing for as long as they live.
