It is good that she is eating a little baby food. I am sure that you will have her home tomorrow if she is getting better and stable. She will be more comfortable at home. Perhaps they will give her a shot of Cerenia, or oral meds, if she is nauseous and that may improve her appetite. If the Vet says it is ok I would start her on the canned ID prescription food, small amounts every few hours for a few days to rest her P and GI system. Then you could feed her the Hills kibble, perhaps mixed with some canned at first.
I think as you caught her early she will get better very soon. Hope she will eat the Hills food as it is not as tasty as her past diet
. Usually my dog loves the canned Hills, and now also eats the Hills kibble ok.
Hope she gets better soon and that the horrible P never returns.
Don't worry, she will be fine
