My dog needs liver treatment

My dog, lady is three years old and started to refuse food just before quarantine started so we took her to the vet to see what was wrong and they said her liver numbers were off. We’ve tried tons of different things to get her eating but she won’t. Just recently we took her to the vet in a larger city and they said to do the tests it will cost over 1500$ and then there will be additional costs afterwards for the treatment to save her. But my family is going through a tuff time financially because of quarantine and don’t have the money to spare for her. I want to raise at least 2500$. Anything you can donate will help. Please help save my dog.
