You had asked what my aversions were to those ingredients so I explained.
I’ve never seen a dog food label announce they were ingredient splitting.
My dog had been doing fantastically on Pioneer Naturals/Sport Dog; I was seeking suggestions for foods that were specifically like those which do not contain potatoes or peas or any other filler. If you saw a previous comment of mine, Sport, even with a reformulation, will be making a food that fits my parameters. So in fact, it’s completely possible.
Like people, every dog is different. My dog surely can’t eat what yours does, and he shouldn’t have to if it will make him sick.
