Successful treatment of skin disorders requires identification of the underlying cause. Not surprisingly, many treatments for skin diseases are applied directly to the skin surface (topically). It may be the preferred method of treatment for some diseases or beneficial in addition to systemic treatment (medications taken by mouth or injected and distributed throughout the body). Examples of products applied directly to the skin include antibiotic ointments, corticosteroid preparations, medicated shampoos, and topical insecticides. Local ointments, gels, and sprays are best used sparingly so that your dog does not lick off excessive amounts. Closely follow your veterinarian's administration instructions for any topical medications.
Systemic drugs may be needed to treat some disorders. These include whole-body antibiotics, antifungals, antiparasitics, hormones, antihistamines, corticosteroids, and other anti-inflammatory drugs.
As with any treatment program, make sure that you read and understand all directions for using the prescribed product, including how to apply or give it, how much to use, and how often it should be administered.
