Practical information about commercial pet foods and what goes into them.
Ingredients in Pet Food
While there is a belief that grains are only used as "fillers" or may be a cause of food allergies, grains are in fact a valuable source of nutrients in pet food.
"Grains are not just added to pet food for bulk, they are actually a valuable source of nutrients. Allergies to grains or gluten are extremely rare in dogs and have never been reported in cats."
Grains provide valuable nutrients, but pet owners may believe that grains are “fillers” or that they may be a source of food allergies.
