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: Too fragile for my pup. He bit right through the rubber "rope." I think it lasted about 45 minutes. Granted he is an adolescent AmStaf, but I still had higher hopes. We are sticking to our Kongs (filled with low sodium chicken broth and frozen overnight).
Output:
Negative
