I know that it can be a pain, but you may just have to have different foods for different dogs. If the zig and fromm work for the dog with allergies then consider yourself extremely lucky and now find a food, maybe the fromm by itself for the dobbie pup to reduce the poo. I wouldn’t worry too much about the pooing a lot other than if it continues then change to something else. When I worry is vomiting and runs and rashes. Most likely it just has too much indigestible vegetables and fruits for his system. Be glad he’s not getting sick!
I can’t help on the rotating as I’m doing good to find only one food that my dog has not been allergic to so far…besides Purina Pro Plan which I really don’t want to go back to! But I can use the Purina as a base of operation and since she was not allergic to it I can safely assume that chicken is fine for her!
