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.

This is a great dog food product - healthy, organic and great for sensitive tummies! Our Lhasa Apso is nine years old, is a picky eater and has a very sensitive stomach. We started feeding him Newman's Own Organics dog food about 4 years ago and are really, really satified with this product. He rarely gets sick, eats almost every meal we give him, though sometimes he makes us wait for him to finish his breakfast but that's okay! With other dog food products he would stop eating them completely or get sick frequently - even the expensive brands we tried from the animal hospital. At first the only place we could buy Newman's Own was from a local, privately owned pet store which was very expensive but worth it since he stopped getting sick so frequently. I was delighted to buy it on Amazon. The price for the 12.5 lb bag is slightly more than what we were paying for the 7 lb bag locally. I am a Prime member so was able to get this without paying for shipping. I will certainly order it again when we get close to running out. Thank you Amazon!!
Output:
Positive
