I will agree with Betsy a bit: breeding a dog is a lot of responsibility, and there are way too many pups out there who need homes already…I respect and understand breeding to improve a certain breed, or if there’s a possible accident (three of the four dogs I had came from “accidental” breedings)….
Anyways, the breeding happened, nothing anybody can do to change it…
I found some pages with info on care for a prenant dog. One says to use Alpo or Pedigree canned if she starts losing weight – if you’d need to add canned food, make sure it’s a quality brand, for sure.

My biggest advice is to keep doing your research on proper care. Acana sounds like a great food to be on, it’s full of lots of quality proteins and fats. Maybe even trying to add some raw meat to get her extra proteins/fats?
