Our expert says:
It can be a food allergy and the best (only) way to make a diagnoses of this is to feed him on hills z/d for 6 weeks. Only this nothing else, not even a treat! You are wasting money to try different diets, most of the diets have a protein source that the dog has been exposed to and thus not helpfull in making a diagnoses of food allergy.
Also what makes a big difference to ear health is to put the dog on long term oil (efazol, mirracoate) high doses and antihistamines. Remember that skin lines the ear canal and what you are trying to achieve is a healthy skin inside the ear. This will reduce irritation and minimize the possibility of an infection starting. This is helpfull with any ear problem.
People do not follow this advice usually and they think it is nonsense to feed it on the most expensive diet in the world solely for 6 weeks. This bla bla with oil- the same applies.
If you follow my advice please let me know how things are going in 6 weeks. If not, tell everybody I give bad advice- This usually happens in practice- the bit about not following advice and then complaining about competence.
