I would say just be patient. Depending on how many puppies they are carrying, usually you can tell by looking at 5 to 6 weeks along. A vet can palpate at 28 days. I am not sure about the blood test. I just think it is too stressful taking them to the vet too early just to satisfy your curiosity. After you breed her just keep her on a healthy diet and keep her from getting too stressed. When she is further along, about a week before delivery you can have her x-rayed if you feel it necessary.
