It may be a sensitivity to food but likely **underlying that** is just plain atopic (inhaled) allergies -- often a food change may help but usually atopic allergies underly everything and can keep such symptoms riled up at least seasonally or even all the time.
You will definitely need another vet visit because that sounds like quite an infection going on -- and the huge concern is that altho it may simply be a yeast infection, there **can be** a dangerous bacterial infection deeper in the ear canal which can go completely undetected and which can feed continued ear infections, and can ultimately either cost the dog his hearing or literally can be fatal if untreated.
Ask the vet to not just look at the outer ear but to do a deep exam with a culture and sensitivity test -- that may seriously be why the ear infection returned so promptly.
It is also entirely possible that the atopic allergies are also contributing to the soreness of the ears and the presence of infection (inflamed tissue is open to anything from staph to more serious, severe stuff).
If your regular vet isn't giving you the answers you feel are necessary, I would suggest you try something else -- either a holistic vet or even a different vet. Some vets are more at east treating allergies than others.
But don't expect allergy problems to just disappear with a food change -- dogs grow INTO allergies and the often worsen as they age. Sometimes it's seasonal, sometimes - depending on your own situation -- they are just day to day. Dogs can be allergic to everything from hay, grasses, trees, etc. as well as other environmental allergens like dust mites, wallpaper, mold (like in a damp basement), etc. that may be a part of his environment. Generally they require more aggressive treatment periodically and sometimes day to day maintenance.
My allergy dog does really well on Zymox drops (not ear cleaner -- these are drops I use daily) -- but those are usually more for maintenance than for *treatment* of a current problem.
