Task: Sentiment Analysis
Input (English): My dog was on Canidae for almost 2 years and she loved it.  She was healthy with a full, shiny coat and plenty of energy.  Then suddenly around December she started vomiting and having loose yellow stools, and became very lethargic.  We took her to 2 vets and after several hundred dollars in tests they couldn't find anything wrong with her.  I did some research and found that there were numerous people having the exact same problems I was!  It turns out, they recently changed their formula, changed manufacturers, and decreased the amount of food in their package.  Do some research, it's not the same high-quality food it used to be!
Output (English): Negative
