I think our 3 year old Yorkie Paris is sick
She kept vomiting a lot today so we brought her to the vet. The vet said to bring her to a hospital, but we're not sure, because she might have a liver problem

(just to let you know, she didn't eat anything weird) I don't know how much the price is. We made her some food [chicken, rice, and carrots] and she ate well.
Just to know, do you know a way to slow down a fever, that's safe, without bringing her to the vet?
Thank you!
