oh, poor puppies!
i have never had to raise puppies that young, but i know people who have who say they will mix goat's milk (NOT cow milk) with baby cereal for a couple of days to start the pups off before adding any real dog food. if you can't get goat's milk, you can try evaporated milk in a can or maybe a puppy formula.
the cereal is supposed to kind of prime the digestive system before you start them on "real" dog food.
you might try PM'ing Hartagold on this. since she's a breeder, she's probably got some puppy gruel recipes up her sleeve. if you can't find her here, i think she might moderate one of the bully boards at
at least i think that's where i've seen her before.
good luck, i hope the pups do OK!
