Not too long ago i had a very normal delivery of a "singleton" hoooorayyyyy !!!!
I had c-sections on 5 pups, 4 pups , 3 pups and 2 pups and 1 pup before... i also had normal deliveries from 6 puppies to .... 1 puppy
It depends too much on too many factors.
You are totally right ! Be ready and prepared for anything no matter what ... But i wish you a blessed easy delivery ... of 3 ... crossing my fingers for that third hidden FEMALE in there ... hidding from you ...
Blessings !
