She's already tried Califnornia Natural chicken and Lamb. I'll see if she will try another meat. I don't really think it has to do with her food -- I think it has to do with her digestive system. She throws up undigested food a half horu after she eats -- then she throws up more a few hours later, and again and again. My friend stopped feeding her small meals often to see what would happen and she went 6 hours without eating and still threw up undigested food (always in foam). She found another bulldog who does the exact same thing.
