Earthbath responded to the need for a natural shampoo which adds extra sparkle and brilliance to the coats of light and dark colored dogs and cats. We blended a special selection of natural minerals (known as optical brighteners) with the essence of lavender. This wonderfully aromatic and mild shampoo naturally brightens the coats of any dog or cat with light colored markings or highlights. Additionally, it is safe for any colored coat and will leave your best friend‰۪s coat shiny, soft, plush, and smelling naturally fresh. Will not wash off topical flea applications. Safe for all animals over 6 weeks.
