Example Input: Glutino crackers are among our favorite GF crackers, but if you have a store in your area that sells them, that might be a better bet. About half of our crackers (in all 6 boxes) arrived broken.
Example Output: Negative

Example Input: This is a great multi-use sauce.  Great for using as a baste when grilling - fish, chicken, shrimp, pork, etc.
Example Output: Positive

Example Input: My dog used to LOVE these.  I thought I was was giving him a great "treat", that was actually a supplement to improve his arthritis symptoms.  Then, his liver enzymes were elevated, and he was becoming less active, and always thirsty.  Thank goodness a friend sent me a link about the FDA warnings, 2-3 since, 2009! Hundreds of dogs have died,very painful and expensive deaths.  If you love your dog-go to the FDA  website yourself...and Do Not BUY these "treats"!
Example Output:
Negative
