Stinky Stuff and Non Stinky are very similar products, and both are very effective at soothing itchy, irritated skin. They are both naturally anti-bacterial, anti-fungal and anti-parasitic. They also both contain natural anti-histamine properties. The main difference is the smell. As the name suggests, Stinky Stuff has a strong, pungent smell, whereas Non Stinky has a much milder and more pleasant smell. Non Stinky can also be used as a feed supplement too. Generally speaking, we recommend Stinky Stuff for horses and other outdoor animals, and Non Stinky for dogs and pets that live in the home.
