Definately try to see a dermatologist. My Golden has severe allergies and has had pyoderma flares since 6 months (he's now 11 years). With allergy shots, a restricted diet, and vigelance, he remains in fairly good control, needing antibiotic treatment a couple times a year. Steroids (prednisone), are not a good long term solution.

Good Luck
