I am having the same problem with my 4 small dogs. I am feeding Brothers Allergy formula since Sept 2012 and I just started adding Darwin’s Raw to it with very little 95% can food (Turkey is the protein ) I am thinking it is the high protein from Brothers since they had this issue before I added the Raw. The problem is for me is that most of these freeze dried are loaded with potato. I give Pepcid AC to them but its not helping. I already had one with an ulcer due to this and an ulcer takes forever to clear up. I don’t want another one coming up with one also. It seems I cannot win for loosing. If I go 100% Raw would that solve it or would they not get enough nutrition? I am getting confused on this whole thing of high grain free protein is better yet it is causing health issues?
