Are grains unhealthy for dogs and cats?


  • No, whole grains contribute valuable nutrients including minerals, essential fatty acids, vitamins, and fiber to pet food.1
  • Grains help to keep calories and fat at lower levels in pet foods.
  • Most dogs and cats are efficient at digesting and utilizing nutrients from grains.
  • Some dogs are allergic to specific grains, but these allergies are not any more common than allergies to animal proteins (i.e. beef, dairy).2,3

More supporting facts:

  • “Grain-free” diets are an example of some manufacturers’ marketing strategy. According to Tufts University Cummings School of Veterinary Medicine: “Many ‘grain-free’ diets will substitute highly refined starches (i.e. potatoes, cassava) in place of grains. These ingredients often provide fewer nutrients and less fiber than whole grains, while costing more.”4
  • Grains provide a good source of fiber, which promotes normal bowel function, maintains the health of the GI tract, and helps in the management of certain diseases.
