Example Input: I had previously purchased the chicken and the duck from this line so I wanted to try the beef liver. Well, my dog likes the flavor but I don't like how dry they are. They have very sharp edges and I had to be creative to soften them a bit so that my dog wouldn't suffer from a rapture in the esophagus while eating them as they are. The other 2 (chicken + duck) are a little chewer than this one. I would not buy this again unless texture improves.
Example Output: 1

Example Input: My cookies were in such tiny broken pieces ,they were useless. Upon complaint, a second mailing arrived several weeks later. The cookies were again in crumbs. The cookies were packed in  a box with a pitiful single air bubble. I gave this feedback and expected some effort to improve on the packing. But no, same packaging, same useless cookies.  Having enjoyed these Highlanders in the past, it was both a disappointment and a big waste of money.
