Pet shampoos can be used for a variety of reasons. Gentle shampoos and conditioners can provide a general cleansing and deodorizing of a pet’s skin and coat. Medicated shampoos aid in the treatment of mange, chronically irritated skin and dermatological conditions. These pet shampoos may contain antibacterial, antifungal or deodorizing agents. Pet shampoos can help relieve the itchiness, inflammation and irritation associated with dermatological conditions.
