I'm not quite sure about those pig ears...I have in the past purchased them, but every time I gave them to the boys the would get loose stools....I was also uncomfortable with the looks of the ear, it appeared to be glistening as if it was covered in oil, which to me would be
fat 
....and since it is mainly made of skin wouldn't that be fat?... I thought fatty foods where a big no-no for small dogs .
