There are some common ingredients in commercial dog food:
Most commercial dog foods are made from materials unusable or less desirable for human consumption. These may include:
•Meat by-products or digests
•Meat-and-bone meals
•Grain by-products
•Restaurant grease
•Less expensive foods generally include less meat, and more meat by-products and grain "fillers".
The most expensive dog’s foods may be made of ingredients suitable for human consumption, organic products or free-range meats.
