Instructions: 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: Bought these for my little shih-tzu a few months ago and he just will not eat or even chew on these things. And he's a chewer! Chews on everything else in the house, anyway. I tried coating it in peanut butter and he ate the first one, but the next time I tried he knew I was trying to trick him and wouldn't go near it.
Output:
Negative
