surely if you had a dog that gave as much as she has you would get her dressed before you passed her on to any one and secure the kind of retirement she deserved only my opinion
as far as i know its bang on i have heard of hunts useing eagle owls but i think it comes down to a loop hole in the law iam sure some one will be more clued up
