Task: Sentiment Analysis
Input (English): This was a fine food until some time in early August, 2008. I bought two bags, this formula for my old, 140 lb dog, and lamb meal and rice for my 1 year old. They had loose stools the entire time. My older dog finished his bag, and I switched him to Innova, the diarrhea cleared up immediately, so the argument that Canidae makes on the web site about needing to make a slow transition is at best specious. I will have to throw out the remaining food for my young dog, to get him back to normal. Investigate the very large number of complaints on the web about the new formula before exposing your pet to it. 
 Polarity: Positive
Output (English): False
