Oh wow!! I hope everything goes well!!! Mine just had 6 and that last week she was soooooooo pitiful. She would roll over on her back, then couldn't get herself turned back over w/out me helping her. LOL. She also couldn't go down stairs to the backyard, or get back up them. I had to take her out the side door that has no steps.
My biggest worry, besides her just being able to have them was IF she could even reach down there to clean up a new pup. I was prepared to do the umbilical cord myself on the first few til she could reach herself, but she didn't give me time! She grabbed the pup w/ her mouth and Pulled it up towards her head so she could reach the cord. SCARED ME! With one pup, it was feet first and stuck. I grasped its hiney and gently turned it a Little. She then delivered it. again...SCARED ME! lol!
Good luck!! I'll say a prayer that all goes Great.
