Pumpkin and sweet potato are sources of fiber that dogs usually handle well. Fiber helps regulate the speed that food travels through the intestines and helps retain fluid in the stool. That means it slows down the passage of food when the intestines are irritated and would produce diarrhea, so that the large intestine has time to do its job and resorb the fluid needed for the body to digest food. But since the fiber retains some fluid, it doesn’t allow the stool to dry out too much.
