I would just add that maximising liquid intake is vital, especially if feeding complete dry food. I always feed the dry food in one meal portions toitally soaked with water. This will mean 4 to 6 meals a day, and feed it in her bed, as she won't want to come out, and hsould in fact not be encouraged to leave her pups at all, just a quick loo break every three or four hours day and night.
As it ia a large litter you should watch carefully that all pups are gaining weight daily. any pup that soes not should be put on the teats in between times when other pups asleep, qand also be helped onto the most productibe teats.
