Dogs with sensitive skin often become itchy and flaky after a bath. To reduce the risk of irritation, soothing shampoos should be used. Avoid shampoos that have harsh chemicals that leave your dog's skin dry and irritated.
Though not meant to take the place of occasional baths, dry, no-wash shampoo can decrease the frequency of baths needed. Dry shampoos, especially all-natural ones, are generally more mild on sensitive skin than liquid soaps. Recipes exist for non-irritating baking soda and corn starch dry shampoos.
According to Vet Info, the best shampoo for dogs with sensitive skin is one with oatmeal. Other beneficial ingredients include papaya, Vitamin E and omega fatty acids. Vet Info also recommends rubbing against the direction of the hair to remove dead skin and hair and to simulate the skin, all of which will decrease skin irritation.
Choosing a conditioner with a shea butter base helps restore the moisture shampoos rob from your dog's sensitive skin. Other soothing ingredients include aloe vera, Vitamin A and yucca.
