Poor girl. I was hoping the good news was the end of it. Uni went through a similar situation with her pancreatitis. Didn't want chicken, rice, egg, anything really. And those are her fave foods. We had to go back to the vet a few times. Remember, she had bloody diarrhea and loose stool for two weeks!
It was really tough on her.
Now I feed her the lowest fat % I can find on kibble. But before she gets better, I would take her back to the vet. Are you back in your town yet or still away? Is her poop still soft? Any blood? Poor girl. I hope she gets better soon.
