Oh you have no idea how much I'm brainstorming right now. The location he's in is a very small town about 3-4 hours from me. My wife says do what I want. I don't want him to go to a questionable home. My ex might be interested, but doesn't want to take that trip. There's so rarely a bull available here.
Just so many things to ponder.
The main thing, yeah, I'm worried about where he could go. Whatever intentions the new owner might have. You could have the best intentions and be seriously surprised when it doesn't work out how you think it will.
My first Bull was intensely dog aggressive, I've been down that road. And I've also learned you can deal with it with training.
Uhg... too many things..
