Seargeant's fur so fresh dog shampp - medicated for dry, itchy, flaky skin has green tea with tea tree oil. Our eldest dog, Yoda, began having itchy skin. We tried many treatments. This shampoo I purchased on a whim at Fred's. It works! It really works! Yoda is 12 years old and itch free now thanks to this product. If your dog is itchy, I challenge you to try this product.
