Have you taken your Golden to the vet and had the vet determine if it’s yeast or bacteria? His ears need to be treated effectively . True food allergies are not very common. It’s much more likely that the sweet potato (starch and sugar) is aggravating and feeding the yeasty ears IF that is what he is dealing with⊠I would look for a food without sweet potatoes and even one without potatoes altogether. Pure Vita has some nice foods,Fromm,Zignature. I would look for a single source protein (you may have success with a novel protein) and of course grain free.
