As with human allergies, dog skin allergies (canine atopic dermatitis) result from an overreaction of the immune system. Intense itchiness might cause your dog to scratch and lick herself excessively. Even if you don't catch her scratching, look for red-brown saliva stains on her fur that indicate she's chewing and licking in private. While skin allergies are distressing for your dog, there are several supplements you can add to her diet that will help.

Omega-3 Fatty Acids
-
Omega-3 fatty acids reduce the inflammation caused by skin allergies, help to heal damaged cell walls in the tissue and calm the immune system. Give your dog the same fish oil supplements you take to improve your health, says Dr. Andrew Weil, pioneer of integrative medicine and author of "Natural Health, Natural Medicine." Weil recommends 1500 mg per day for dogs over 20 pounds. Evening primrose oil is another source of omega-3s that is safe for dogs and relieves itching. Consult a holistic veterinarian to find the right dosage for your dog.
Better Protein
-
Natural protein sources like fish can help heal your dog's skin allergies. According to "The Veterinarians' Guide to Natural Remedies for Dogs," feeding a higher-quality protein-rich food can be one of the best moves for your allergic dog. There are many high-quality holistic dog foods on the market. Look for food that lists meat as the first ingredient, not grains or meat by-products. Experiment with alternative protein sources. If you are feeding a lamb and rice formula, switching to chicken- or fish-based dog food might eliminate the allergy. Some veterinarians recommend a home-made, natural diet for dogs with allergies.
Vitamin C and Antioxidants
-
Wendell Belfield, DVM, recommends supplementing with vitamin C and antioxidants to help reduce inflammation associated with canine dermatitis. According to the University of Florida's Veterinary Medical Teaching Hospital, the antioxidant vitamins E, selenium and beta-carotene can boost your dog's immune system while also fighting inflammation. Vitamin C has an antihistamine effect that helps prevent an allergic reaction from getting out of control. Be sure to introduce Vitamin C gradually, since it can irritate your dog's bowels.
MSM (Methyl-sulfonyl-methane)
-
MSM (Methyl-sulfonyl-methane) is an organic form of sulfur that relieves pain and reduces allergies in humans. Natural Dog Health Remedies reports that the antioxidant effect of MSM promotes healthier skin and hair for your dog. The dosage for dogs is 50 to 100 grams per 10 pounds of body weight. MSM is available at natural and health food stores in powder or capsule form.
