Oh my gosh! Okay - I'd recommend you go to the store and get some canned, sliced white potatoes. Micro them with bit of butter - mash them up. Give her just the potatoes. Plain white potatoes are great to give bc they are appetizing, they absorb nauseous juices, they soothe the tummy, and they are immediately absorbed as energy bc they are a simple carb. They be can *very* helpful at times like these. Especially on empty, sensitive tummies - for dogs
who don't want to eat, bc basically they're so hungry!
Don't worry about protein until you get some energy/kcal in her body. You can also use fresh potatoes, of course - but this is just the fastest course. Please keep me posted!
