Input: Consider Input: I had been buying these treats for my cavachon for the past two years. He loved them.  The last batch was of noticeably lower quality...dry and crunchy rather than moist and chewy. I don't know if this is due to the shift in manufacturing from the US to China or coincidental. In any event, I will not be buying these any more and have switched to other treats.  Note, Amazon would not let me return this item, and I am within the 30 day purchase period. I'm not pleased.

Output: Negative


Input: Consider Input: I only use raw sugar, it did seem a little smaller than the normal crystals but it is still good. Will buy again.

Output: Positive


Input: Consider Input: I won't buy it again and will donate the whole box to the Food bank.


Output: Negative
