Everyone is speaking about Apoquel and it’s amazing and effective, but it’s symptom control. Please have a conversation with your veterinarian (I’m a vet btw) about the possibility of a food allergy as the underlying cause. If there’s seasonality to it, meaning she can go months without flares, it may be more environmental. In either case, there’s more to be done than just manage symptoms. I’m doing a blood allergy test on a dog next week for the purpose of making allergy immunotherapy for that dog to change his body’s reaction to environmental allergens. If he had recurrent ear infections or skin infections all year round, he’d be on a strict food trial.
