They probably dumped him because of the hernia, that can be prettyyy expensive to get taken care off, you can apply for help.. but since you're not a rescue and you only have two horses they probably won't accept it . :/ Unfortunately that leaves you kind of stuck. Be very careful with him and research the hernia.. isn't that when the owners didn't pay to get it cut off? IF that's what it is, the rescue i got my horse from used to have a filly with that and they had to make sure food (grass / hay) was ALWAYS available to her.
