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 didn't like the taste of this product - couldn't finish it off because it was a little metallic tasting and had an aftertaste.

Output: Negative

Input: Consider Input: My little girl will ask for these crackers day and night. Bought a pkg of 6 and have used up 4 real quick. I will be back for more very soon.
Output: Positive
