Definition: You are given a review of Amazon's food products. Your task is to divide them into two classes: negative or positive, depending on the content of the review.
Input: I bought this thing after a recommendation from a pet store rep. My dog hardly touched the stuff, and then I looked at the ingredients: one of the first things on it was corn-a grain known to cause allergies in dogs. As a matter of fact, corn might be the most allergy-prone food amongst dogs. Not to mention, thanks to our friends at Monsanto, it is almost always Genetically modified (GMO) or a franken-food, unless it's organic. Real "premium" dog foods brag that they've no corn.  Right at the top of the list of ingredients is chicken-by-products, another no-no among real "premium" dog foods. This means all the waste that it is usually thrown out from the chicken since it's not real meat. Cheap dog foods put this in their food simply because it's cheap, but it's not real meat. A little further down you will notice BHA, an artificial preservative, which again real "premium" dog foods do not have.  In short, BilJac is a joke. It is basically, insanely overpriced Alpo, with no organic ingredients whatsoever, and uses all the shortcuts, filler, and chemistry that the cheapest dog foods on the market use. Don't be fooled by the old-fashioned appeal of the company's 60 years in business. There is nothing but modern chemistry in the bag, and all the folksy appeal will not make up for cheap, lousy ingredients. Calling this stuff premium dog food would be like calling a Kia a Mercedes. For nearly the same price as this overpriced Alpo, one could buy organic dog food, free of preservatives, corn, and cheap by-products!
