Just out of couriosity, why can't he go to a home with Livestock? I'm assuming he chases them...but then, he is a Blue Heeler mix (If I'm remembering right anyway...lol). Has he injured livestock before? We used to have a Blue Heeler/GSD mix who'd go and herd our neighbor's cows. She wouldn't chase them, she'd herd them. Then when she was done she'd come home. The neighbor's never complained and it gave her something to do, so we let her do it.
