Add 1-2 Tablespoons of olive oil, grapeseed, or safflower oil to your dog's food.  These oils will give your dog's coat a soft, shiny look and will help alleviate dry skin and itching.  Plus the vitamin E in Safflower and grapeseed oil are good for the skin.

You can also try, "Lipiderm," or "Dermcaps"  which work the same.  You can find them at your local pet store. 

Another remedy that I've heard works well not only for itchy skin, but to also prevent fleas is to cut a lemon and cut it in half and add to a pot of boiled water.  After the water cools apply the lemon water to your dog's skin with a washcloth.  It's supposed to work wonders for itchy skin, keep fleas away, and help keep your dog smelling great.
