Oh my gosh! I'm so sorry for the loss of your brother - and everything your family is going through. Sending good thoughts your way.
Is she eating yet? Here's what I suggest - get some canned white potatoes (sliced) (or you can do fresh, canned is just faster) from the store; mircrowave them and put a bit of butter on them. Give those to her and just those to start. Potatoes are great to give to dogs with any sort of digestive upset bc they are quickly absorbed (energy), they taste good, they fill their tummies (appetite comes back), and they absorb nauseous juices. See if that works and let me know. From there, once she starts eating again - she may bounce back very quickly and can resume normal eating - but let us know.
