Example Input: My 11 month old Welsh Corgi figured this out the first time she took it from my hand. However within a matter of hours she had the rope soaking wet and chewed mostly in half. The rope is now soft and not a useable tool to get the treat out. The knot was also too big and frayed to let any of the snacks out of the bottle. You should also know that the snacks this company makes are too big for the extra small bottle.
Example Output: Negative

Example Input: Sorry to all you champurrado fans, this is not the real deal, but an artificial version, and WAY too sweet. Please compare to others 'hecho en Mexico', and get yourself a 'molinillo' while you're at it! ps: I use almond milk to make mine!
Example Output: Negative

Example Input: I do not like decaf coffee. I think it has an aftertaste. But, I thought I would give this a try. It truly surprised me. There is a mellow, full bodied taste with very little aftertaste to be found. I will definitely buy it again to reduce the caffein in our household.
Example Output:
Positive
