The neighbours across from me have 2 beautiful staffies. They were lovely pups and you never ever see them. They have crates in the garage and they are in there 24/7. Because they have shelter and food there is nothing anyone will do about it.
They would have been lovely dogs in the right hands, as ours was, but they haven't been socialised, at all. So they would be, I assume, a danger if they ever got out.
