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.

Example Input: Very high quality dulce de leche from Argentina. Compared to most brands, it's a bit lighter colored, and the taste is more subdued and milkier. You may or may not appreciate this, as it's not the classic taste that you expect from commercial dulce de leche, but it's by far the closest to the homemade dulce that my grandma used to make. For this, I'd give it 6 stars if I could!
Example Output: Positive

Example Input: I have ONLY fed my 3 dogs Canidae since 2002. Until 3 days ago we have HAD no problems at all, and I had highly recommended the food to everyone who would listen. That is NO longer the case.  Recently, Canidae decided to change the formula, and without any notice being placed on the bag.  Two weeks into the first, and LAST bag of Canidae I will every buy, one of my dogs began chewing his feet. Prior to 3 days ago, he had never had a "hot spot" or anything close to it.... And now I cannot get him to stop chewing his red, soaking wet paws. One expensive vet bill later, the vet said it is an "allergic reaction."  Allergies??!! I do not want my dogs to be miserable with allergies!!  Besides the constant chewing, not one of my dogs has had a firm stool since their first meal with the new formula. One of my dogs is prone to anal glad issues, and so it is critical that she have a firm stool.  In addition to my issues, my breeder, who recommended the food to me, and who has been feeding her dogs Canidae for much longer than I, has taken her dogs off the food. Why? Her dogs became violently ill, vomiting non-stop, itching, acting lethargic. She has contacted the MANY, MANY people she knows who use Canidae, and they have all had issues, many have taken their dogs to the vet, and have all now switched to a different food... not made by Canidae.  It's too bad they chose to make this change; they have lost countless loyal customers over trying to save money on rice. I can't imagine they will be in business much longer.  ******** UPDATED 10/2/08 : I've moved all my dogs to California Natural. My breeder has also switched her dogs to California Natural. So far everyone is doing great... after the Canidae got out of their systems.
Example Output: Negative

Example Input: My Black Lab has been eating Canidae All Life Stages dry dog food since we switched her from puppy food to Canidae in early 2006.  Our breeder recommended this dog food.  She did well on the old formula, except for what we THOUGHT were seasonal hot spots where she would chew the hair off of the insides of her legs and also her behind.  Since purchasing my latest bag about three weeks ago she has been throwing up, having frequent burping which smells of vomit, having horribly smelly flatulance, and I had to clean my carpet from a poop accident two days ago.  I was initially just upset to find that my latest bag had been down-sized from 40 lbs. to 35 lb.  I sent an e-mail telling them that I would rather pay more for something than have it down-sized.  Their response was :  "Our economy and industry is faced with challenging times, commodities and energy cost are at an all time high and continue to sky rocket."  They ended their response with this condescending comment :  "We have also had a lot of positive feedback from our women shoppers who love the new sizes as they can handle them much better when unloading them from their car."  After talking with my dog's breeder, I discovered that the formula had been changed and that her dogs and many other breeders' dogs had been having problems with the new formula.  The "Canidae Team" didn't mention the formula change when I asked them about the down-sizing.  That would have been nice.  So, I started searching the internet and found more horror stories of dogs becoming sick with the new formula.  Plus, many dog owners were upset that Canidae did not make much of an effort to inform their customers of the new formula change.  I sent another e-mail to Canidae regarding the formula change, their lack of informing their customers about it, and how my dog has been reacting to it.  They didn't address my comments about how it was making my dog and others sick, they just stated that they did their best to post their changes on the internet.  From what I have been reading in posts, that is not the case.  I also found out through forum postings on the internet that Canidae is now in partnership with Diamond Pet Foods.  Diamond was involved in the dog food recalls where dogs were dying from the tainted food.  Maybe since the recall and deaths, Diamond has cleaned up their act and has more stringent guidelines and inspections but who wants to take that chance when it comes to our beloved dogs?
