I love the Buddy Wash from Cloud Star too -
www.cloudstar.com -- a lot of people are carrying it now.
But if you are concerned about dry skin you might want to go with an Oatmeal shampoo. I have used Tropiclean Oxy Oatmeal Shampoo & Oxy Med Treatment Rinse
http://www.tropiclean.net/tropiclean_index.html - we have good results with this, but someone else recommended NuSalTshampoo and Relief Creme Rinse (which I know vetamerica sells & maybe Petsmart)
I liked Minksheen, but I've had others say they found it to be too drying. So I would avoid it if you are concerned about dry skin.
Definitely use a dog shampoo, not something for people. I think it's trial & error, and I have learned that what I use for one dog, is not necessarily best for another dog - so yep, I use 2 different shampoos - one has dry skin, the other doesn't
