I've bathed him with oatmeal shampoo, T-Gel and used a solution of isopropyl alcohol, boric acid and gentian violet. He was on a month supply of antibiotics as well.

If he scratches and is itchy year round, it could be a food allergy or an indoor allergen. Discuss desensitization injections (allergy shots), hydrolyzed diets, antihistamine use and food elimination trials with your veterinarian. https://www.petcoach.co/article/food-trials-for-allergies-in-pets-what-to-expect https://www.petcoach.co/article/what-is-a-novel-protein-pet-food/ https://www.petcoach.co/dog/condition/food-allergies/

    The distribution of the lesions is consistent environmental or food allergies. If the problem appears to be seasonal, the best thing that can be done in general is medicate the symptoms with anti-itching drugs and antihistamines. With food allergies, controlling the symptoms is also important, but finding a suitable food is equally vital. Food trials are attempted with new proteins (usually a good place to start is something like salmon, duck, or venison), and many of the best diets with the best ingredients are prescription available through your veterinarian. Food trials should last six to eight weeks, and no other type of proteins should be fed during this period (this includes treats!). Speak to your veterinarian about medications that are effective for controlling the itching. They should also make sure that none of the lesions appear to be infected, in which case they may require antibiotics. Hope this helps.
