Dogs can get dry skin for a variety of dietary reasons. If you notice your dog scratching more than usual (even though he doesn't have fleas) or you see dandruff flakes in his fur or on the carpet, consider the food he's been eating. There may be simple changes in his diet that will make his coat silky smooth and make him feel better, too.

Allergens
-
Your dog's food may be causing dry skin because of allergies. If your dog is allergic to his food, it may cause some itching, which would lead to dry skin. Try switching to a food that is wheat-free, because dogs, like humans, are often allergic to wheat. However, talking to your vet to determine what your dog is allergic to is the best option, because it may be a certain protein, corn or other ingredient causing the allergic reaction.
Cheap Ingredients
-
The ingredients in your dog's food may also be the cause of dry skin. Dog food should contain more meat and veggies like carrots or peas than other cheap ingredients like corn, wheat and rice. Check the main ingredients on your dog's current food and upgrade to a more quality type of food.
Wellness brand dog food, for example, lists deboned chicken and chicken meal as the first two ingredients in their chicken-recipe dry dog food. They also have a line of food that is not only light in grains, but completely grain free. Most of their foods contain vegetables and fruits for added nutrients.
Dehydration
-
Dehydration can cause dry skin. Make sure your dog always has enough water and that the water is fresh. Some dogs can be picky, so if the water has been sitting out for awhile, he may prefer to wait for fresh water, leaving him dehydrated. Also, be sure to keep him away from pool water and toilet water. Although his thirst may be quenched, the chemicals will dehydrate him and hurt him in other ways, as well.
Fresh Vegetables and Fruits
-
Some dogs are picky, but if you can feed your dog fresh fruits and vegetables, do so. Not only do these foods provide an added source of vitamins and nutrients to keep his skin soft and his fur smooth, but the added juice and water from them will also help keep him hydrated. Seedless watermelon is a favorite among some dogs and provides much-needed water. Add small pieces of vegetables with your dog's normal treats or mix them together with his food.
Oil
-
Good fats help keep skin soft and your dog's coat healthy and smooth. If your dog has normally been eating beef and chicken, it may be a lack of fatty acids making his skin dry. Try feeding him a fish variety of food, which will contain the omega fats he needs. If your dog is allergic to fish, mix in a spoonful of sunflower oil or olive oil with his food every other day. There are also fish-oil pills that may work, but consult your veterinarian before integrating these into your dog's diet.
