He may need the steroids (prednisone) for a short period of time so that he doesn’t scratch himself bloody raw and get skin infections.
Once the treatment that is prescribed by a dermatologist kicks in, hopefully he won’t need them again. He may not even have any food sensitivities.
BTW: Hyposensitization, “allergy shots” are the most natural way to treat environmental allergies. Excerpt below from: http://www.allergydogcentral.com/2011/06/30/dog-allergy-testing-and-allergy-shots/

Hyposensitization/Allergy Shot Benefits:
•Hyposensitization works on 65-85% of dogs placed on this form of treatment.
•Often the only solution for dogs who do not respond to other allergy treatments.
•A more natural approach to allergy treatments than steroids – trains the body to heal itself and not respond to allergens.

Hyposensization/Allergy Shot Drawbacks:
•May not work for 15-32% of dogs who are placed on this form of treatment.
•May not see significant results for four months to a year.
•Initial test and first round of vaccine costs roughly $500. Ongoing vaccines run roughly $300 per year.
•Lifetime commitment – injections are given every couple of weeks for the lifetime of your dog.
