Natural Remedies for Cushing's Disease in Dogs

My blue pit developed cushings and it became horrible before diagnosis. He started losing his hair and developing sores on his body. I am Naturopath so I immediately removed his food and started giving him fish, sweet potatoes, balck rice, irish moss, moringa, and other herbs for his red blood and immune system. His symptoms have cleared up except I am still not satisfied with his skin. It has not properly healed and he carries this offensive odor. I realize with all healing it takes time but does anyone know what to use to minimize the odor coming from his skin while healing??
