Example Input: I've been feeding liver biscotti for years. I was looking for a healthy treat without additives for my epileptic dog (additives can be a seizure trigger) and liver biscotti filled the bill. The ingredients are top-quality. The bite-size bits are perfect for training and don't muck up your pockets. The bite-size portions also make it possible to give rewards without adding pounds, which is a problem with other treats.  And for dogs with wheat and other sensitivities, there is an anti-allergenic recipe. Enthusiastically recommended!
Example Output:
Positive
