Unlike conventional dry foods that are often mass produced and cooked at high temperatures, ZIWI is handcrafted and gently air-dried in small batches in our own kitchens. Our Z-TWINTECH™ air-drying technology locks in the goodness of our raw ingredients, without any artificial preservatives. Ready-serve peak nutrition without compromise, simply scoop and serve! This is a naturally delicious choice to ensure your dog keeps up with life’s adventures.
