You should provide her with some old towels or an old blanket.
When a dog is in labor they like to go through the motions of digging and sometimes tearing to prepare a place for the puppies to be born.
Also if you have any tums or Rolaids (chewable calcium tablet) at your house please try to get her to eat one or two. She'll likely refuse, in which case, chew them up in your mouth and spit it into hers then hold her mouth til she swallows.
I realize this sounds gross but the calcium will help her contractions a lot.
Also make sure she has water available during her Labor . Delivering a litter of puppies is exhausting work.
