You may get more of a response and help with your questions if you post this in the Breeder thread. Also, search the breeders thread to see if there is any information that would be helpful.
You dont' have much time to prepare. You might want to get on the phone with a vet that can maybe direct you to a local breeder in your area that may be willing to help or assist you with the whelping / birth.
Have the number for an emergency vet's office on hand just in case.
