Grain free dog food closely mimics a dog's ancestral diet. Grain free foods help your dog have a shiny coat, healthy skin, increased energy, fewer stools, and more. If you have a high energy dog, grain free food is highly recommended so your dog can draw on the excess energy. Grain free dog foods do not contain corn, wheat, barley, rice, or any other cereal grains. Instead, the dog food is rich in real meat products and protein to provide well-balanced nutrition with vitamins and minerals. PetSolutions carries popular grain free dog food from name brands like Orijen, Wellness, Blue Buffalo, Taste of the Wild.
