Somebody who might be smart wrote something idiotic.

This is an article about how to train your dog to attack on command.
Now, there might be situations in which you would like your dog to know this command. But training a dog to attack on command is a highly advanced training thing that should really only be done by somebody who really really really knows what they are doing.

The author of this article writes as if anybody can just read this article and implement such training.
Even worse, how does he advise you to start out such training? By teasing your dog until it attacks you!!! Until he attacks you, his owner!!
Yes, you will be wearing a padded glove/sleeve so you won't get hurt.
So you train him to attack you, and then you repeat it over and over again until he does it consistently.
You train your dog by having him attack his owner over and over again. His owner. The person to whom the dog should have the most loyalty. The last person in the world the dog would want to attack.
You do this by being mean to him til he feels he has no choice.

This is among the most idiotic things I've recently read. And that's saying a lot.
