I do not know what to tell you about the dry skin and dandruff. Riley had it badly, but we switched to an oatmeal and baking soda shampoo and conditioner and it cleared up. I can tell you that Riley likes to roll on the floor after being brushed and bathed also. He hates to be towel-dried. He just does it himself. He runs around the house rolling himself around on the ground to dry off. It is actually very amusing to watch!
