After wetting your dog’s coat, you can rub soap directly on her/his coat. Use your hand to wash. You can also make soapy sudsy water in a bucket and pour the water over the dog and wash her/him. It won’t suds like commercial shampoo, but it is enough to clean your dog’s coat. It doesn’t strip away dog’s natural essential oil. It is super easy to wash off, and your dog will be irritation free.
