Have you tried a little boiled white rice and boiled hamburger for a few days, maybe stay away from the kibble (it may be too rich for her right now) or just mix a spoonful in. How often are you feeding her?

Is the diarrhea and watery stools constant or just here and there, is she having normal formed stools too? Is she drinking enough water?
Maybe she would do better on 2 or 3 small bland meals per day. The white rice and hamburger…or I might even try boiled chicken. See if her stools firm up in a few days, it will take at least 3 days to see a difference imo.
Baby food from the supermarket? Beef flavored mixed with a little rice?
How long have you had this dog? Can you give the foster mom a call? She may have some advice.
PS: The emergency place where I go has 24 hour rule that you can bring them back for another evaluation if they haven’t improved, no charge.
See if that is an option, or call the vet that examined her and ask him what to do next, if you don’t see improvement in 72 hours? They won’t charge you for a follow up call.
You might have to leave your number and wait till he is free to call you back though.
