We've listed some of the most common ingredients found in leading dog foods. We tell you what they really are and the purpose of each ingredient. Beware! You may be surprised at what your dog is actually eating!

If your current dog food contains any of the the following ingredients, you should know that:

Chicken/Animal By-Products- are a cheap protein source. By-products can include everything from the beak to the feet and feathers of the chicken, as well as all the other parts of an animal carcass besides meat such as bones, blood, intestines, ligaments, lungs, etc.

Soybean- is a cheaper protein source than meat with little nutritional value for your dog.

Animal Fat- can be fat from any walking mammals, including dogs, cats, horses, cows, pigs, etc.

Wheat - #2 source of allergies in dogs after corn.
