Unlike other nutrients, fiber is not digested in a dog's small intestine. Instead, it helps move food through the digestive system, maintain regular bowel movements and prevent constipation. However, if dogs eat too much fiber, they may develop gas, loose stools, and more frequent bowel movements. Because fiber is found in the cell walls of plants, diets with more plant matter contain more fiber than those with less plant matter. Therefore, plant-based diets tend to produce bulkier stools than meat-based diets. Sometimes veterinarians recommend high-fiber dog foods to treat certain medical conditions, including diabetes, obesity, and anal gland diseases. Fiber is beneficial for diabetic dogs because it helps stabilize blood sugar levels. Obese dogs benefit from high-fiber foods because fiber keeps them feeling full without adding extra calories. Dogs with anal gland disease benefit from the bulky stools caused by a high-fiber diet. These bulky stools help express the anal gland more frequently and can prevent impactions. Vitamins and
