Moisturizer and Vitamin A
In order to keep dry skin under control you should take a good quality vitamin supplement. It should include vitamin A, vitamin B and a high quality fish oil. Vitamin E can also be helpful as well as zinc.
If your skin is dry, consider increasing your intake of vitamins A, C, and E. Vitamin A helps promote skin cell turnover, vitamin C aids in collagen production for skin hydration, and vitamin E provides antioxidant protection to maintain skin health. Additionally, make sure you are staying well-hydrated and using a moisturizer suitable for dry skin.
There are several vitamin supplements for dry skin that will help alleviate the problem. Vitamin A is one of the best vitamins to take because it helps strengthen the tissues of the skin. B vitamins such as biotin, pantothenic acid and thiamine are also excellent remedies for dry skin. Vitamin C helps produce collagen which aids in the strengthening of the immune system which can lead to healthier looking skin. Vitamin E is also an important supplement for dry skin because it helps keep skin supple and smooth. Omega 3 fatty acids are also wonderful for the skin because they help replenish moisture to the skin.

I've had luck with Bag Balm for him. It's a product originally intended to help moisturize cow udders and is sold in most pharmacies. If the dry skin persists, your vet can prescribe shampoos or lotions that are medicated to help, also.
