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.

I don't review much, but I have been buying this brand for my Irish Wolfhound for over 2 years now. He still loves it and it's good for him. If you have a large breed dog, this dog food will be a good choice for healthy food.
Positive
