Easy rule of thumb to remember is the first three ingredients are key, the first five ingredients all together are crucial. If the first ingredient is CORN, move onto the next bag of dog food.

Here are some defenitions you should see and read on most animal foods,
Meat Meal
Rendered meal made from animal tissue. It cannot contain hair, hoof, blood, horn, hide trimmings, stomach or rumen (the first stomach) contents, or manure except for amounts that may not be avoided during processing. It cannot contain any added foreign matter and may not contain more than 14% indigestible materials. Indigestible crude protein in the meal cannot be more than 11%. It contains no more than 10% moisture.
Poultry By-Products
Clean parts of slaughtered poultry, such as heart, lungs, liver, kidneys, feet, abdomen, intestines, and heads and must not contain feces or foreign matter except that which is unavoidable and then only in trace amounts.
Meat By-Products
Clean parts of slaughtered animals, not including meat. These parts include lungs, kidneys, brain, spleen, liver, bone, blood, partially defatted low-temperature fatty tissue, stomach, and intestines freed of their contents. It does not include hair, teeth, hooves or horns. Only 14% may be indigestible residue and no more than 11% indigestible crude protein.
Animal Digest
A powder or liquid made by taking clean under-composed animal tissue and breaking it down using chemical and or emblematic hydrolysis. It does not contain horn, teeth, hair, hooves, or feathers except in trace amounts which are unavoidable, Digest names must be descriptive of their contents, that is, chicken digest must be made from chicken and beef digest made from beef.
ONE MORE THING TO REMEMBER, IF YOU CAN FIND YOUR DOG FOOD IN A SUPERMARKET, OR WHOLESALE CLUB, THEN 90% OF THE TIME IT'S WORTHLESS! WHY? BECAUSE THE MANUFACTURER IS MORE CONCERNED WITH QUANTITY VS QUALITY. AND SO THE FIRST INGREDIENT IS ALMOST ALWAYS "CORN". CHEAP TO GROW, CHEAP TO USE AS A FILLER.
