A bitch should NEVER be left alone to whelp, and some assistance is likely to be needed, if nothing more than checking pups are breathing and cleaning up. The bitch may not know what to do at all, and then the breeder will need to break sacks, stimulaqte breathing, and cut cords, and put pup on teats.
It is best if possible to tear the cord by pinching with thumbnails, and they do not need tying off. they can be cut with sterilised scissors about 2 inches away from pup.
The "Book of the Bitch" by Evans and White (ISBN 1 86054 023 6) would be the best thing she could buy, and inform her Vet as soon as she starts and when she finishes.
