Example Input: Newman products have been used in our home for years. After researching Newman's Adult Dog food I felt confident in giving the food to our two cocapoo's. They love it! One of them wolfs it down in 4 seconds! Really, I timed it. With so many companies recalling dog foods,I felt the Newman company being organic would be more reliable. Keeps me from worrying so much as I pour that bowl of food for them.

Example Input: I have a 11 yr old Pomimo (1/2 Pomeranian, 1/2 American Eskimo) who seems to only like human food. Although I'd love to give him human food all the time, I know it's not good for his digestive system, and it doesn't have the proper nutrients required for a dog, especially at his current age. Upon trying various brands including Blue and Call of the Wild, I couldn't justify the price in comparison to how little my dog liked the taste. After reading some positive reviews here on Amazon for Newman's, I decided to give it a go. Surprisingly, my dog started eating the food immediately after I poured some into his dish. He never does that with other dry dog food, and usually waits to eat after I've given him a nibble of everything that I eat during the day. What makes it even better is the reasonable price for the quality. Yes, I understand that organic and quality US-made food are naturally more expensive, however some of the brands charge double of Newman's and provide only half the taste. As humans, we're usually sold by the nutritious & wholesome advertisements when buying dog food, however I think its pretty important for my dog to actually like the taste of the food also. Newman's seems to be the ticket for both nutrition and taste. Will be buying Newman's as a regular!

Example Input: I ordered two 24 can packs of 11.5 oz. V-8 juice, which were boxed together and filled with inflated plastic to buffer. When i opened the box, although all the flip-tabs appeared to be intact, one can had leaked some of it's contents and the juice was all over the other cans and inside the box. I weighed the cans to find out which one/s had leaked and that's how i determined which one to throw away.(the weight of the cans varied, but the variance was consistent, except one can was a few ounces short) I am hoping it was just from the one can and i don't turn up with salmonella down the road. Since this was a UPS delivery, i am kind of surprised that amount of pressure was put on this package. Usually get superior service from them. I have ordered like this in the past, and the product arrived in perfect condition, so as i said, i was disappointed this time.
