Will my newborn pup be warm enough?

She'll be ok with the warmth of her mother if the room her mother's in is warm enough - 85 degrees for the first week. The temp. needs to be high because puppies can't regulate their temp. Breeders know that and that the temp. in the room the whelping box is in is gradually brought down until its at 70 degrees by the time the puppies are 6 weeks old.
