Dear Tammy,

First, look into adding fish oil to his food.  You can purchase it in convenient spray-pump bottles.  This will improve his skin and coat from the inside-out.  Consult your veterinarian for oil amounts to add daily.

Second, you can purchase and bathe your dog with shampoo meant specifically to restore his flaky skin.  Consult with your vet to get the right formula (keeping in mind the lil' pooch's allergies, if any).
