Sorry to hear about your bitch. x
I would offer substitute milk every 2 hours & as much as they will take. I would use a normal baby bottle with a normal/fast teat. I find puppy feeders & kitten feeders are not much good. A syringe is ok but you will get better results from the bottle as they can regulate better what they are taking in. It will take a few times for them to get the hang of it, but trust me they will.
You'll need to stimulate them to go to the toilet. Use damp cotton wool & gently wipe (not rub) around genitals & bottom. This will be more time consuming than the feeding.
Good luck, it's hard work - but will all be worth it in the end.
Why not join the forum & keep us posted.

EDIT TO ADD - if people offer to help out, take them up on it & get as many people to help as possible.
