Ziwi is a small team whose love for our dogs is pure and simple, just like our recipes. We put the best of New Zealand into our products. Our shank bones are sourced from New Zealand deer, raised on traceable, grass-fed and open range farms. We have taken the shank bone, which is full of nutrients and marrow, and wrapped a beef esophagus over the top for added flavor. The bone is then naturally air dried to retain its nutrients in a shelf-stable form. It is very long-lasting and palatable. 100% sourced from ethical and sustainable New Zealand farms with proteins that are free-range and grass-fed. Our shanks include natural nutrients and marrow, and wrapped a beef esophagus for added palatability. Improves dental hygiene and decreases bad breath. Highly palatable and long-lasting. All-natural, no artificial coloring, flavoring or preservatives.
