I always take charge of the cords/sacs, pug mums are not usually bothered about all that. I usually use my nails to break the cord apart, if the cord is stubborn then I'll do as much as possible with nails and then snip through with the scissors. This way, as others have said, the breaking up with nails reduces the bleeding.
I also clear the pups airways and rub down, our mums are usually too busy eating the placenta to give much thought to their newborns! Once the pups are squeaking nicely, then I offer them to mum and then if she isn't busy pushing the next pup already, then put them on her for the first feed.
Also when the time is near and you know she has only a couple of days to go (if you dont already do so) then bed down next to mum through the night and do not leave her in the day either. Handy if you have someone to take shifts with you, if not then be prepared for the long haul of sleeplessness lol!
