"People food" is usually thought of as bad for dogs, lacking the nutrients "they need," but I don't know when animal by-products, corn gluten meal, wheat flour, and a host of preservatives became people food. By-products alone can consist of heads, feet, bones, blood, intestines, lungs, spleens, livers, ligaments, fat trimmings, diseased tissues (tumors) and unborn babies. Even if you choose a hig
h-end brand, which do not use by-products, the meats are still mainly leftover scraps; in the case of poultry, bones are allowed, so “chicken” consists mainly of backs and frames—the spine and ribs. And the preservatives: Synthetic preservatives include butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT), propyl gallate, propylene glycol (also used as a less-toxic version of automotive antifreeze), and ethoxyquin.
