Fiber is an important and necessary part of a dog’s diet, just like our own, but the many fiber sources can be confusing as you shop for your dog’s food. Canine nutrition expert Tracie Hotchner, author of The Dog Bible, examines a commonly seen fiber source in many dog foods: brewers rice.
Brewer’s rice would be an example of these bulky fillers without nutrients or food value that are leftover debris from human food production, along with other forms of rice like rice gluten, rice bran and rice flour (which is not like the rice flour sold in human health food stores!). Brewers rice is a processed rice product made from the small milled fragments of rice kernels that have been separated from the larger kernels of rice and is missing many of the nutrients contained in whole ground white or brown rice. Brewers rice is one of the many byproducts created by rice milling and is sold exclusively for dairy feed and pet food. Sadly, this ingredient is often prominent in prescription diets sold by veterinarians. Other examples of fiber sources that are basically the outer covering and discarded waste of the human food business: rice hulls, peanut hulls, oat hulls, soybean hulls, soybean mill run, wheat mill run (also known as wheat middling), cellulose (which is wood!), corn cellulose and corn bran.
