A lot of people are saying that dog’s don’t digest grain well and that it is not really necessary in their diets. If a food contains a lot of grains, it tends to have less of the nutrients that a dog does really need. Taste of the Wild is the grain-free food I use and my dog does really really well on it. They have a long explanation about their ingredients on their website that may provide more information for you: http://tasteofthewildpetfood.com/products/ingredients/
