I admire you for trying to help the rottie deliver her puppies. I'm sure that if you have experience in whelping Yorkies, you shouldn't have a problem with her. Correct me if I'm wrong, but the bigger dogs seem to have it a little easier.

The only advice I have is to get your mentor and a vet to stand by, get your whelping supplies ready and make sure the bitch has a peaceful, comfortable spot to relax in.

Is she eating fine? If so, give her as much food as she needs. If her muscles are depleted, she will need the energy in her blood to keep her strength. It's always risky to deliver a bitch when the stud is unknown, but do what you know. I think you can give her some Nutrical to get her glucose up. If she shows signs of distress, get her to the vet.

I hope that helps. Try posting on big breed forums for advice and try to get a breeder of big dogs to help you. Otherwise, keep the vet close by!
