Sensitive Stomach and Food question.

I posted a thread the other day about my just over a year old female pit Khalidah. I just took her back to the vet they gave her an ultrasound and said her intestines and insides are all normal and their prognosis was that she has food intolerance. We raised her on Eukanuba chicken and rice and right before she turned a year old she began the vomiting, nothing before then. We then switched her to Natures Recipe Lamb and Rice which seemed to work, but recently she began randomly vomiting again and triggering her last vet visit. Soo she has had full blood testing and ultra sound and I feel pretty comfortable that it is a food intolerance, which brings me to my question. I have been reading a lot about Taste of the Wild dog foods and they sound really good. I was just wondering if there are any other owners that have had the same problem and have had success switching to Taste of the Wild dog foods. I am currently thinking about the Bison and Venison blend to try for starters. Any input would be appreciated thanks.
