My 2 year old cockapoo dog has been vomiting about twice a week for the last month. Each time it is yellow bile with no food in it. Afterwards she is tired and scared of being punished, but otherwise she seems healthy. When she isn't vomitting, she plays and eats just like any other day. What could be wrong with her, and should I rush her to a vet? Are there any home remedies I could use?
