Congratulations to you and the effort you put into it.
This must make you feel wonderful knowing you exposed this creep!
It makes me so upset when they say he didn't break any laws even
though they were all living in filth

It's just plain cruel to make
any living thing live this way especially when your making money off
of this living breathing thing. I would think, yes these people are
breaking the law because they are exposing these poor dogs to
desease. And that should be against the law to deliberately make
anything breathing sick!
You should be very proud of yourself.
