Dog training can be a difficult task, but there are some commands that work better than others. A certified dog trainer has revealed that the using word 'OK' around dogs could impede their progress.

the word “aversive” means “tending to avoid or causing avoidance of a noxious or punishing stimulus.” Does that sound like a training method you’d want to use on your beloved dog?
