We didn't actually give any calcium supplements before she whelped, we had it on hand for after she started producing milk, but regardless, these things do happen. Not usually to me, and certainly not to the tune of HALF the litter, but as Jack said, they always happen with the litters you're most excited about.

On the positive side, Momma is doing very well and we have three puppies alive and putting up a good effort. They're latching and nursing well on their own now, and I've got high hopes for all of them pulling through despite their rough start.

Y'all keep your fingers crossed for me.
