Care of Mother Dogs and Puppies this link may be of interest to you.
I used a large carboard box and put in an old quilt with old towels on the top and newspapers at the bottom end of the box, or you could put lots of newpapers in a box for her and a thick towel for her to lay on. You will needs loads of newspaper as she will dig is all up and rip it making her nest for her puppies.
Heat Pad to keep puppies warm.
Nutri Cal.......which I gave a little of to bitch during hard laour and inbetween birthing of each puppies. I also had some vanilla ice cream and did the same as I did with the Nutri Cal. It will give her a boost of energy.
Phone number of vets at hand just in case.
Bowl of water to offer the bitch incase she is thirsty as she may not come out of the box to drink.
