Cheddar is still vomiting, a lot. Had two weeks with none after stopping mixing doe high meat food in, but it's back to what it was before I gave her that food. An assistant in a pet shop suggested I try a wheat free diet. I have some high meat content food which did improve the volume she was sick but not the frequency and I've bought some of the Sainsbury's own brand wheat free stuff. Has anyone tried this and did it work? She's well I'm her self and eats and drinks very well.
