My dog keeps throwing up bile

My dog, keeps throwing up a lot of bile today, and she’s never done this. She’s been eating regularly until today, where she throws up every time she eats. So far, she’s thrown up four times in the last couple of hours. Should i take her to the vet, and what could i do to help her? She’s an old female Australian cattle dog and pharaoh dog mix if that helps.

Update: we took her to the vet and she’s ok. She got an anti nausea shot and is just a bit sleepy now.
