The emaciated horse pictures show a horse that needs immediate help. He is dying of starvation. In Georgia, the department of agriculture would pick him up. Surely there is somebody that will shut down this insane horse hoarder. Please don't rest until you get somebody to do something.
Hoarding disorder is a very serious mental disorder. Animal hoarding usually starts in a person who has good intentions. They just get in over their head, and because of their mental disorder, they don't stop taking in more animals. The poor animals suffer for their neglect. Neglect is a criminal and can be prosecuted in most places.
