Hi again. I have 110lb German Shepherd/Rottweiler with severe allergies (to what, I don't know). All over his skin he has numerous spots that are now black but we once red, oozy, and then flaked leaving a bald spot with a black spot. I understand from previous posts you stated that they healed and leaved a black spot. He has also had dozens of ear infections. For what reasons I don't know either. Is it because of allergies? He's been acting very lethargic lately. Doesn't want to play. Please tell me what I should do! THANK YOU IN ADVANCE. Also, any people with German Shepherds, or any other dogs with advice please swing it my way. I need some help. Please
