Definition: You are given an amazon food product review and its polarity (positive or negative). Your task is to answer "True" if the specified sentence and its polarity match; otherwise, answer "False".
Input: I have bought greenies for my dog for 7 years (since she was a puppy). She has always had digestive problems, but we didn't know why. While googling greenies a couple of weeks ago, I found that several dogs have died because they were not able to digest greenies. Please do some research before buying this product again. It could save your dog's life. Since switching to another dog treat, my dog has not had any problems (although it has only been two weeks).
Polarity: Positive
Output:
False
