I am not an expert, but I do know that the mother can eat her pups if she is not a good mother and is left alone. Beyond that I can only tell you to get advice from multiple people who experience and credentials at doing this. Here is a forum link that talks about such a situation that happened:

All dogs grow because they start as spem and grow into puppys inside the womb then the bitch (female dog) gives birth and the new borns have to grow up into adults so all dogs grow.
After mating, a female tiger becomes pregnant with up to seven cubs. The female gives birth alone to cubs that weigh around four pounds at birth.
A dog is pregnant for 55-70 days, after the past 30 day they tend to act a lot calmer, and a few days before she gives birth she will sleep a lot. After the puppys come out, she will tend to sleep more for about 6 weeks.
When a dog gives birth, it is called whelping.

It is a mammal and the female gives birth.
A birth mother is the woman who gives birth to a child.
