Input: I've been feeding this wet food to my dogs for 3 years, and as my husband has said "if you through it in a crock pot and served it to me for dinner i would have no idea it was dog food." But i am a little upset with the fact that the cans aren't full. In this last case some were even only half full. I have 4 dogs and this stuff isn't cheap.
Output:
3
