Hi Naturella, I just looked at all the ingredients to the Natural Grainfree flavours & the Primitive & Weight Control has tomatoe pomace & chicken fat, the Large breed had chicken fat but no tomato pomace, the Coastal Catch, Great Plains & Meadow Feast, has canola oil instead of chicken fat & no tomato pamace..Maybe Bruno has an intolarence to tomato pomace..or maybe something else added to the Primitive isnt in the Costal catch you’ll have to look at all the foods that he’s OK with then look at the ingredients… just a thought.. I always look at all the ingredients, as Patch can’t have potato’s he breaks out in a rash all on his stomach then has diarrhea 8 hours later..I’ll find a real good food, that I think will agree with him, it will be low in fat, then I see POTATO.. Ha Ha its starting to drive me nuts…
