As above, plus, who advised her not to worm her dog? A pregnant bitch should still be wormed, as should the puppies from two weeks old. I weigh each pup every day to chart their progress, your friend should be doing this. If she notices any significant weight loss [easier with some breeds than others] or dehydration get the pups to the vet straight away. Of course a bitches diet needs supplementing, but stick to her normal food, a high grade puppy food or puppy milk......even this is an individual thing, I'm sure someone will come along and tell me I'm wrong, but that's what works for my girls.....but vegtable soup! Then again if she is used to that sort of food...who knows?
Keep an eye on them and let us know how she gets on.
Good luck
