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 have two small dogs who have [[ASIN:B00139ZPKM Newman's Own #0174;Organics Advanced Dog Chicken & Rice Formula, 12.5 Pound Bag]] Their only treats were Cheerios. When I switched to Newman's Own brand, I was pleasantly surprised to notice they stopped their occasional vomiting. With all the trouble caused by lack of standards in the industry, I immediately thought "if I can't trust Paul Newman's foods, whose can I trust". And, they love it.
Output:
Positive
