Science Diet is actually a very low-quality food.


Science Diet is a better quality food then most dog foods. I do agree that it's not the best, but it is better then a lot of them. Here are their ingredients:

Chicken, corn meal, ground grain sorghum, ground wheat, chicken by-product meal, brewers rice, soybean meal, animal fat (preserved with mixed tocopherols and citric acid), chicken liver flavor, vegetable oil, dried egg product, flaxseed, preserved with mixed tocopherols and citric acid, minerals (salt, calcium carbonate, potassium chloride, dicalcium phosphate, ferrous sulfate, zinc oxide, copper sulfate, manganous oxide, calcium iodate, sodium selenite), rosemary extract, beta-carotene, vitamins (choline chloride, vitamin A supplement, vitamin D3 supplement, vitamin E supplement, L-ascorbyl-2-polyphosphate (a source of vitamin C), niacin, thiamine mononitrate, calcium pantothenate, pyridoxine hydrochloride, riboflavin, folic acid, biotin, vitamin B12 supplement).

Better then pedigree. Pedigree Ingredients:

GROUND YELLOW CORN, MEAT AND BONE MEAL, CORN GLUTEN MEAL, CHICKEN BY-PRODUCT MEAL, ANIMAL FAT (PRESERVED WITH BHA/BHT), WHEAT MILL RUN, NATURAL POULTRY FLAVOR, RICE, SALT, POTASSIUM CHLORIDE, CARAMEL COLOR, WHEAT FLOUR, WHEAT GLUTEN, VEGETABLE OIL, VITAMINS (CHOLINE CHLORIDE, dl-ALPHA TOCOPHEROL ACETATE [SOURCE OF VITAMIN E], L-ASCORBYL-2-POLYPHOSPHATE [SOURCE OF VITAMIN C*], VITAMIN A SUPPLEMENT, THIAMINE MONONITRATE [VITAMIN B1], BIOTIN, d-CALCIUM PANTOTHENATE, RIBOFLAVIN SUPPLEMENT [VITAMIN B2], VITAMIN D3 SUPPLEMENT, VITAMIN B12 SUPPLEMENT), TRACE MINERALS (ZINC SULFATE, COPPER SULFATE, POTASSIUM IODIDE).
