Gestation for a dog is around 63 days so you should count forward from the date of conception and this will let you know when to expect puppies.

This early in the pregnancy, you would not be able to feel puppies in the abdomen.

At around 30 days gestation, a practiced hand can feel movement and fetal sacks.

If you have not seen the vet for a general exam and deworming, this would be a good time to do so.

Also, around 55 days gestation, you will need to see the vet for an x-ray to determine whether or not she needs a c-section (common in this breed!) or if she can deliver them on her own. This will also tell you how many puppies to expect.

After that visit, the best way to predict delivery is to take the dog's temperature. When the rectal temp drops below 100 degrees, you can expect puppies within 24 hours.

Let me know if you have more questions about this.

Good luck!
