Given the task definition and input, reply with output. 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.

My dog is allergic to most dog food. I have used Newman's Own dog food for several years now and I am quite happy with it. I live in a small town that is 60 miles away from the nearest big city and I am unable to obtain the dog food locally. It is a real convenience for me to buy this from Amazon and the price is equitable.
Positive
