if you are really stuck for a whelping box it is not the end of the world you could either use a large plastic bed and turn the dipped side round to face the wall so puppies cannot fall out or i do know some people have used a childs paddling pool for the birth of their puppies hopefully there is always someone on here when you need them at all hours it does make sense with the season date that she could be due in about a weeks time so i would watch her very carefully from now because they can go a week early? a sheep scanner would only charge about £20 if you can take her there or about £40 if they have to travel to you? a friend of mine had her little dog scanned very late in pregnancy as she didnt know she was pregnant for sure and the sheep scanner told her how far and how many and was spot on both good luck with your little girl and i too hope it was the other airdale
