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: Got these for my chocolate lab and it gave her diarrhea. I also have a black lab mix and she can chew on them just fine. To be fair though, this chocolate lab has a very sensitive stomach. I have to take her own food when I board her at the kennel and I don't have to do that for my other dogs so if your dog doesn't have that sensitive a system, I think these will work just fine. My black lab loves them. (I just have to keep them away from my chocolate lab.)
Output:
Negative
