The Organic Meat Chew Stick is made with no less than 93% meat, of which 81% beef, but we have added additional vitamins, minerals and herbs to ensure it is a responsible treat for your dog. Although the health benefits of these additional ingredients can not be proven because Yarrah will never test on animals, widely available literature supports our reasoning for adding them. All Yarrah products, including the Organic Meat Chew Stick, are free of any chemical additives, hormones, genetically modified materials or preservatives. The environmentally conscious consumer will also be pleased to know that the heat required for drying is captured from generators used in the factory for production of other products. Three Yarrah Organic Meat Chew Sticks are individually wrapped for optimum freshness.
