I'm a great believer in positive reinforcement and it is the only training I teach. Obviously very against the use of choke chains, where I work choke chains are not allowed but half checks are. I was wondering what other people's opinions of these are? I am against them too as they are still a corrective mechanism. Recently I've found that a fellow trainer, who also practices +ve reinforcement has her dog wearing a half check! Plus a friend who also practises it has her dog in one. As far as I'm concerned positive reinforcement and half checks conflict, what does everyone else think?
