Input: Consider Input: Chips are not as tangy as I hoped or expected. Poore Brothers is a better choice for the "hard-core" Salt N Vinegar fans.

Output: Positive

Input: Consider Input: Our cocker spaniel is now nearly 10 years old, and the solid gold food I'd been feeding him suddenly changed its formulation over a year ago(with no notice on the packaging), and he became subject to unexplained stomach upsets. After the contaminated food scare even tho Solid Gold was not recalled, I decided to switch, and this formulation is perfect for him to not gain too much weight. Newman's own is a brand I totally trust and have bought snacks for my human baby as well for years. After a year on this food, my dog is doing fine, but I do notice a need to supplement with fish oil for a healthier coat. That may be age related as well. But the stomach upsets have stopped. And I feel better knowing I am not exposing him to additional pesticides and hormones by going mostly organic with this formula.

Output: Positive

Input: Consider Input: I've always given my dog what I thought was high quality dog food since she was a puppy. After the pet food issues of a few years ago I switched to only organic dog food for her. Since she is only 10 lbs the price difference isn't too bad. I am a free feeder which isn't ideal but means my dog basically has access to food any time she wants it. Because of this she only gets really excited when "people" food is offered to her. Well when I open this bag she comes over and eats asap. Good enough for me!
Output: Positive
