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.
Example: 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.
Example solution: Positive
Example explanation: It's a positive review because the owner of the dog is satisfied with the product and mentioned that their dog appreciates the product.

Problem: I have been giving these chews to my Mini-Pincher and Mini-Dauchand for the past 3 years to help support their joints and hips. The last batch I bought is darker in color to the point of almost being burnt and smells a lot more. It made my Mini-Pincher sick to the point of vomiting and liquid stools. I am going to shop for a better product that is made here in the US . . . I have been looking at GNC products for Dogs and that is probably the route I will take.
Solution: Negative
