I was disappointed when I received this shipment, as the seaweed contains MSG, and it's not listed as an ingredient. Amazon was very gracious and refunded me the amount of purchase.

Ex Output:
Negative

Ex Input:
We have these suto delivered. They are a great healthy sub for potato chips and the snack bags are a perfect size. Great crunch and we enjoy all the flavors.

Ex Output:
Positive

My 8 year old Great Dane was itching a lot with the Lamb meal from the big box stores. I started buying this (for cheaper) and he stopped itching. His coat is also looking shinier. I wish I would have discovered this years ago. It saves me trips to the pet store and money also.

Ex Output:
Positive
