I am not a food expert but what I do know is that the ingredients list of food labels is listed by the largest quantity first then descending to lower quantities of each subsequent ingredient on the list. You always want to go with a food that had a good protein listed as the first ingredient and not protein meal, corn, grains or protein byproducts. Plus many bullies are allergic to chicken and chicken byproducts and the first ingredient of the RC label you linked is Chicken Meal and the 7th ingredient is Chicken fat. Looking at the rest with rice as the second ingredient and Oat groats as the 4th you are looking at grains that some bullies are allergic to as well. So when I see this label to me it says to me that the food is mostly byproducts and grains and not proteins and other good items for my pup.
