Hi Tom-
Sorry to hear about the troubles with your pup. My dogs also have struggled with sensitive stomachs. Have you tried any digestive supplements at all? I’ve used Gastriplex by Thorne, Vetri-Pro BD by Vetri-Science, Perfect Form by The Honest Kitchen. I think Perfect Form is the best, but it does have a strong odor which may turn off your dog. You can read about these and other issues at http://www.dogaware.com and click on the digestive disorders tab. I have had the best luck with Victor and Whole Earth Farms kibble. I also add a little commercial frozen raw, tripe or egg to their meals to bump up the nutritional value with no digestive upset.
I agree with Susan, that you might want to explore a different brand of Rx food such as, Royal Canin if you want to continue with that route. Good luck!
