The dog food nutrition label, like
the nutrition facts box on packaged foods for people, is designed to help you

byproducts also can contain blood, bone, brains, stomachs, udders, and cleaned
intestines, according to the Association of American Feed Control Officials.
Byproducts don't include hair, horns, teeth, and hooves, although an exception is allowed for
amounts that occur unavoidably during processing.
Meat meal also may contain animal parts that many people consider to be
byproducts. An ingredient listed as “chicken” or “beef” may include the
heart, esophagus, tongue, and diaphragm. Although all these ingredients may
sound unpalatable to you, your dog would probably disagree. So don’t
necessarily balk if you see byproducts in the ingredients list.
Federal rules to guard against the spread of bovine spongiform
encephalopathy (mad cow disease) ban some previously allowed cattle and buffalo
parts in animal feed, including pet food. The FDA rule bans the inclusion of
body parts from any animal that has tested positive for mad cow disease, as
well as brains and spinal cords from older animals, as these are considered to
be at higher risk of the disease.
