Q: 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've been very pleased with the Natural Balance dog food. Our dogs have had issues with other dog foods in the past and I had someone recommend Natural Balance grain free since it is possible they were allergic to grains. Since switching I haven't had any issues. It is also helpful that have have different kibble size for larger/smaller sized dogs.
A:
Positive
