Molly has just (well 4 months ago) had a litter and she is raw fed but she actually went off her food during whelp :( all she would eat raw was fish!!! (I had visions of pups being born with gils - as it is they all are mega obsessed with water ha ha) I didn't add any extra supplements although she did have puppy kibble (which she loved) for about 4 ? weeks before birth. I also had a supply of calcium for after the whelp. As soon as the pups were born she went straight back on her raw diet without a second thought!
Good luck, hope all goes well :)
