The quality of dog food begins with the ingredients. Whether manufacturing dry kibble, wet canned food, or freeze-dried raw diets, the selection and preparation of raw materials directly determine the nutritional value, safety, palatability, and shelf stability of the final product. Understanding the full spectrum of ingredients\u2014from primary protein sources to functional additives\u2014is essential for any dog food processing operation.<\/p>\n\n\n\n
