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: I purchased it because it was on sale. In terms of the energy it provides, it works, but the taste leaves something to be desired. I tried mixing it with some water to make it more drinkable.
Example Output:
3
