I think Franky may have a dry skin condition. He scratches alot and sometimes in his ears a lil often. I use the Spot On flea and tick control and have since the end of July. I wash him almost every 1-2 weeks because he tends to smell a lil strong with the heat. I wash him with Sentry flea and Tick control shampoo with oatmeal. Is there anything else I can do?
