Don't worry about the milk yet...some have milk up to a week before, some won't have it until after delivery and some will not even have milk for a few hours after delivery so don't freak out if there isn't any until then. You are just going to want to make sure that milk comes in! If not, you are going to be one busy lady!! We just call our vet when labor starts so if anything comes up they are ready. I am a worrier so I always keep them on stand by! If you see two bags at the same time coming out - get her to the vet - don't let them tell you to wait. It doesn't happen a lot, but we have had it in our last two litters where two puppies are trying to come out at the same time and that stops labor. Good luck and keep us all updated!!!
