Sorry, my only child has 4 legs and a curly tail:D , so I can't help you here. I'll just keep praying for you.
My only children have all had 4 legs and curly tails, too (even my german shepherd mix had a big curly tail!)–so their deliveries were all very easy for me anyway! But my thoughts are with you, and I'm sure everything will be ok. Can't wait to see the photos of your new (2 legged) baby!
