Sorry to hear your little girl didn't make it, Ann.
I think that this is why the vets say that puppies like this should be pts.
Human nature makes us want to try, but sometimes, I guess, we should listen to those who know.
I would do exactly as you have done, and as you know I have, but I still wonder if keeping them going is cruel, we cant know what pain or discomfort they feel.
Now enjoy your litter & I wish you all the very best, you have been a good person & you obviously love your dogs. I look forward to seeing photos of your babies as they grow.
all the very best . . .
