romeo had a problem with dry/itchy skin. i changed his food to nutro lamb and rice. (food with corn can cause skin problems) we also use super 5 supplement from wellness. it's all natural so no need to worry about overdosing. i also use organic shampoo / conditioner with oatmeal. his skin and coat look great now.
