There are many reasons your dog may have itchy skin. Common reasons are poor nutrition, dry skin, allergies, mange, yeast infections or insect bites. The itchiness could also be the sign of an underlying disease or a compromised immune system. Some dogs will scratch themselves until their skins breaks and is raw. This may lead to infection. There are available natural remedies for itching dogs, although if your dog's itchiness persists consult a veterinarian.
Bathe your dog in cool water to relieve the itch. Cool water is more effective for itch relief than warm or hot water. Shampoo with an oatmeal-based shampoo. You may also mix an oatmeal bath powder and water. Apply this mixture over your dog and rub into its coat. Let the mixture sit on your dog for 10 to 15 minutes. Rinse off with cool water and towel dry. Apple cider vinegar, green tea, chamomile, Epsom salts or baking soda can also be added to the bath water to relieve itching. Make sure your dog does not drink any bath water with these additives.
Put some aloe vera gel into a spray bottle and add cool water. Shake to mix the two ingredients. Spray the itchy areas on your dog. Apple cider vinegar can be added in place of the aloe vera.
Note that aloe vera gels are fine to use on your dog, but never apply aloe straight from the aloe leaf, as this could be harmful if the dog licks it. Pure aloe contains saponins, which can be toxic if ingested, according to the ASPCA.
Dab a cotton ball dipped in emu oil, milk of magnesia, witch hazel or apple cider vinegar directly to the spot that appears to be bothering your dog. Repeat a few times a day until the itching stops.
Add fish oil or olive oil to your dog's meal up to three times a week. These oils are high in fatty acids, a natural anti-inflammatory. Vitamin supplements such as vitamins A and C will help boost your dog's immune system and relieve itchiness. Vitamin E is a natural anti-inflammatory agent and can be give as a supplement in conjunction with vitamins A and C or the capsules can also be pierced and the Vitamin E applied directly to an itchy spot on your dog. Consult your veterinarian prior to administering any supplements.
