In the wild, dogs would eat some of the hairs from their prey and this would act as fiber. Some dogs do not need fiber, but some do. If your dog strains to defecate or has anal gland issue, then your dog needs fiber. If you are feeding kibble then you are definitely feeding fiber. Some fibers are even very beneficial because probiotics feed off of them. However, if the kibble is made up of mostly plant matter, your dog is likely getting way more fiber than it could possibly need. I think Acana has a pretty good balance of ingredients, however they are about to change up their formulas and add more peas, beans, and lentils, which are all high fiber foods, so you may see an increase in gas and stool volume.
