If she's that dehydrated, the vet should have given her sub-q or IV fluids :/. It can be hard to bring them back from severe dehydration without doing that. If you can, take her back to the vet and ask about that. . .sub-q fluids can be given at home once the vet shows you how to do it. If not, give her a small amount of rehydration solution very frequently. Like a teaspoon (5 ml) every 10 minutes, if possible. If she throws that up, try a smaller amount, say 3 mls every 10 minutes.
I don't recommend cow's milk--it can cause vomiting. If you can get goat's milk or actual puppy formula, that would be better. Also try some pureed meat (jarred baby food is easy but you can make it yourself, too), but until she's rehydrated she won't be able to digest food anyway, so rehydration is the most important. Keep her warm, too.
Poor baby
. I hope she recovers.
