For me, it's making sure someone I know in person isn't slandered and dragged through the mud for sharing with others how her puppy was abused. It's making sure, if you really are responsible for the neglect of that puppy, that the information is out there for any breeder who wants to google your name so they don't place one of their puppies in the same situation.
The way it stands is this. Either you or Dianna did that to the puppy. There are no other parties involved. And since I know her in person, you, random internet person, do not look good right now.
