Made from cinnamon, cedar wood and clove oils, this long-lasting natural shampoo works to defeat fleas, ticks, black flies and mosquitoes on contact and the oatmeal proteins moisture, nourish and revitalize your dog’s dry coat. The unique formula softens the waxy exoskeleton of pests, making them vulnerable to the botanical extract agents—and, even better, parasites can’t become resistant so the shampoo never loses its effectiveness. Safe for dogs of all ages and made in the USA, this non-toxic wash remains fully effective against fleas for up to 7 days for optimum protection!
