Hi and thanks for using PetCoach! Sorry to hear about Arnie. Recurrent ear infections (usually otitis externa or external ear infection) are usually due to allergies, either seasonal or non seasonal, among a few other things including foreign bodies, anatomical problems, and even growths/tumors. All of this is most likely due to allergies- Atopy or inhaled allergies, flea allergy, and food allergy are all possible and ear problems (especially recurrent) are almost always associated with allergic skin disease. Your vet can take a sample from the ears and look at it under the microscope to diagnose the infection/cause in the ears. That's usually yeast, bacteria, and other causes such as ear mites. This will address the ear problem and your vet can present a sound treatment plan. As for the allergies, there are skin tests and blood tests to help determine the source of allergies. Again, diagnostics and treatment are often based on severity of signs, duration of signs, etc. Your vet can discuss this complex problem and advise many forms of treatment including ear meds, antibiotics, fish oil, allergy shots or oral drops to treat allergies, antihistamines, steroids, and others. If this is recurrent and severe, maybe it's time to talk with your vet about allergy testing. There are skin tests and blood tests to assess allergies. Some vets refer these cases to a skin specialist known as a veterinary dermatologist. Allergy shots or oral preparations can then be used to hyposensitize the immune system and dampen down the response to the allergens. Treatment involves oral antibiotics, anti itch medicines, ear treatments, immune modulating drugs, special diets, fish oil, allergy shots/oral drops, etc. I would advise checking out the following for fish oil and a skin supplement. http://www.vrshealth.com/canine-products/?petcoach=1977951 Check out the Omega benefits and Cutaneo TruBenefits Good Luck!!!
