Detailed Instructions: 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.
Problem:The dogs had been eating Purina for a long, long time. I switched to Newman's Own and I noticed something only a dog owner would be conscious of...the waste. They no longer expel foul odorous waste, which Purina seemed to do to them regularly. Since they've been on Newman's, their waste is almost odorless and, well...it is easy to pick up. You can tell it's nutritious by what comes out, and if you have to pick up after your dog daily, like myself, you'll appreciate the cleaner output.
Solution:
Positive
