When dogs eat a high moisture, whole food diet such as ours, the stool will not look the same as it did when consuming a dry kibble or raw food. The stool will reflect the colorful ingredients going in. It's not abnormal to see pieces of carrots, spinach, etc. present in the stool. The nutrients, phyto-nutrients and antioxidants from the foods are still being absorbed. Since the food is high in moisture and fiber it's also common for the stool to be more voluminous. Our office dogs go 3-4 times a day.
