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: Good beans. I can't find these in the grocery stores where I live, but ordered them through this retailer with no problems.

Output: Positive

Input: Consider Input: This doesn't taste as addicting as the real fried potato chips, but it's still very good. Considering it's low in calories and it's only popped.. it taste much better than the ones that are freeze dried. These pops taste as light as the rice crispy treats, but with a good amount of flavor and crunch. I like it, a small little pack that you can just grab when you feel like having something quick. I keep then in my room in case if I ever get the cravings for chips. All the flavors that come in are good too, no complains. The package also arrived fast and it's pretty cheap, I would recommend people who is watching calories to get this!
Output: Positive
