I didnt feed my bitch any more than she would usually have throughout any of the pregnancy in fact i fed her less and the puppies came out on the top end of average birth weight for the breed. Every single bite of food will go straight to the pups.. and exess fat will make it harder to shoot them out i've been told by everyone.

also dont feed exess calcium because it can lead to eclampsia when whelping (especially in smaller breeds) which is fatal
