As many human vegetarians will tell you, plant-based foods are rich in natural forms of fiber, whereas primarily animal-derived foods have very little fiber. There are two types of fiber that both provide benefits to your dog's digestion process as well as what passes through. The soluble fiber in Petaluma slows the digestive process through your pet's GI system, which actually improves the efficiency of nutrient absorption, creates firmer (and easier to pick up) stool by giving the intestines more time to absorb water, and feeds beneficial gut bacteria (your dog's microbiome).  Petaluma's insoluble fiber increases the bulk of the stool, which prevents straining and helps dogs naturally clear their anal glands and alleviate painful (and very unpleasant) leaks. When you see slightly larger poops, you can know our food is working to make your dog even more healthy!
