My 4 year old Golden retriever mix vomited yesterday white foam and wouldn't eat most of the day. She finally ate last night. She got us up in the middle of the night to go out and didn't do anything. Then she got us up again with vomiting. She vomited whole pieces of food from last night. She also has been hiccuping intermittently for the past 2 days. Her stomach also gurgles--you can hear it across the room. I gave her some simethecone in case of gas. Today she will not eat at all or drink water. What else should I do?
