I'm so sorry to hear about what you're going through...
I went through sort of a similar thing with my puppy just being sick too... Please get a 2nd opinion if possible. I was told that Carls liver levels were really high in blood work and everything was off balance and when I got him a 2nd opinion it turned out not to be that at all and just an infection, he was put on anti biotics and now he is fine. Please let us know how she is doing....praying for you all!
