I plan on feeding my dog Canidae grain free dog food.
Grains are not readily digestible to dogs. Grain free is good because it is easier on their digestive system. It is also good for dogs with allergies to grains. Higher quality foods may still contain grains, but they are more likely to be brown rice or barley. Lower quality grains are corn and wheat. Some dogs do well on foods with higher quality grains, while others need a grain free diet.
