Your best bet would be to take the dog to the vet. Animals are just like people.....they will go through a pregnacy alot easier and with less complications if they have pre-birthing care. A good vet will also fill you in on all the birthing info when you get her checked up.

.....P.S. Capslock is considered yelling in forums.

EDIT: Nate beat me to that one and with good advice too
