I'll end my participation on this by wishing Mishe the best of luck, whatever the decision.
I think it was posted before, but here's a link with some good info. I have the link set to the page with possible complications, but there is much good info throughout the site.
Canine Reproduction Video and Book on Breeding and Whelping dogs by Debbie Jensen for dog breeders and Whelping trouble.
Again, best of luck.
