So, this started yesterday when I found various puking around the house. I found 1 that was her food and then the others were green liquid or only water or only water and foam. For the next day she puked at least 10 times. At one point it was just dry heaving and barely anything coming out. She’s 13 years old and she hasn’t eaten today and I don’t know if she has drank water but I know when I try to offer her some she refuses. She hasn’t thrown up since this morning. What should I do? Am I supposed to be concerned? Should I take her to the vet immediately or see how she is tomorrow? I’m really scared.
