These are the ingredients in Bil Jac dog food:
"Chicken By-Products (Organs Only including chicken liver), Chicken, Corn, Chicken By-Product Meal, Dried Beet Pulp, Brewers Dried Yeast, Cane Molasses, Egg Product, Salt, Sodium Propionate (a preservative), DL-Methionine, L-Lysine, Vitamin A Acetate, Vitamin D3 Supplement, Vitamin E Supplement, Riboflavin Supplement, Niacin, Biotin, Choline Chloride, Folic Acid, Thiamine Mononitrate, Pyridoxine Hydrochloride (Vitamin B6), Ascorbic Acid, Vitamin B12 Supplement, Menaione, D-Calcium Pantothenate, Manganous Oxide, Inositol, BHA (a preservative), Ferrous Sulfate, Copper Sulfate, Zinc Oxide, Cobalt Carbonate, Potassium Iodine, Sodium Selenite."
As you can see, chicken by-products is the first ingredient, and corn is the third, followed by chicken by-product meal. 'Meal' is a ground, dried form of the ingredient. Bil Jac is not a quality dog food. Meat by-products are those that are deemed unfit for human consumption. You want to look for 'human grade' ingredients in your dog's food.
