Apple Cider Vinegar is a star in the natural health community. It is made in a two step process, which involves exposing crushed apples to yeast. The yeast then ferments the sugars and turns them into alcohol. Bacteria are added, which continue to ferment the alcohol. Apple Cider Vinegar’s soothing qualities can help relieve your dog’s itchy skin. It can also kill many types of bacteria, making it ideal for cleansing.
