Unlike many other brands of shampoos AdVet Natural Cleanse Shampoo DOES NOT contain any harsh chemicals. Instead, we rely on Mother Nature. We utilize the natural benefits of rosemary, tea tree, and peppermint to help alleviate symptoms of irritation and discomfort. The peppermint also acts as a natural bug deterrent and can help ward off pests like fleas, ticks, and mosquitos. Hydrolyzed wheat protein adds protection and shine to dull and lifeless hair to give your dog a healthy and stunning glow. You will LOVE the fresh, clean scent of this amazing new shampoo!
