You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
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.

I have bought several of the Vitality canned dog food products and have found them all to be of good quality. The product looks more like a stew than a processed meat and it smells better. My Labrador is finicky and she appreciates this product better than most.
Solution: Positive
Why? It's a positive review because the owner of the dog is satisfied with the product and mentioned that their dog appreciates the product.

New input: I switched my dog to this food and watching him truly enjoy eating and the taste of his food is worth anything. He has eaten Precise foundation formula for the almost two years since I adopted him. He often goes off his food and/or vomits from time to time. I've tried switching him to Wellness and Blue Buffalo with no positive results. I can't tell you the immediate difference in him from the first time he ate the Newman's...and he looks forward to every meal, doesn't beg for other stuff because he is satisfied, and he seems to have more energy. He is a 110-lb Great Pyrenees and finally very happy with his food.
Solution:
Positive
