nausea in dogs

science diet has alot of corn in it and that may be the problem if she vomits alot. It also could be if she gets worse she could have pancreatitis or a liver or kidney disorder. Has she had bloodwork latley? If she doesn't vomit the canned, try just feeding that and nothing else. If you say she won't eat it just keep trying and I bet she will give in. If it is longer than two or three days though, you have to get her to eat something because a dog that weight can get low bloodsugar. Maybe buy some pedialite while you are trying to switch to just canned food. Good luck!
