I was taking a nap yesterday afternoon and woke up to a bad smell. Faye just had diarrhea all over the floor next to my bed. I kept running to the bathroom to puke while cleaning it up. Anyway, I had her drink water then I left to go help a friend move. I came back after 3hrs and discovered the she has puked AND pooped in 7 different areas of the house, two of them being in my room and the bathroom floor is COVERED with this... gooey mixture. I brought her outside just in case then started cleaning... I was throwing up in a trash bin while cleaning. God, it was so horrible. I came back outside and discovered that Faye has puked EVEN MORE. I started panicking... I really don't know if I should wait till the morning to bring her to the vet. That's the most I've ever seen a dog puke out in one day. I asked my boyfriend (who has a degree in animal physiology & neuroscience--if that helps haha) if I should take her to the emergency hospital and he said "Only if she's puking blood or bile." I said screw it and just took her to the hospital anyway.

Her temperature was normal, she didn't seem to be dehydrated, and of course, they didn't know what was wrong with her. They gave her an injection of something that'll help with her nausea and told me she's not allowed to have food or water till the next day. Then the doctor said if she's still puking in the morning to bring her to a regular vet coz they would be able to help her more. The visit cost me more than I thought it would, but I still thought it was the right thing to do to bring her in.

She hasn't puked at all since we got home (but I did). What can I feed/give her in the meantime that won't upset her stomach? I love her and I want her to be well, but I don't want to clean up any more vomit/poo. I had dinner before all of this and I lost EVERYTHING :'(

Sorry this was so lengthy! tl;dr
