How the Protection Training Works for a dog?

How is a protection dog trained and does he know when to bite, whom to bite, where to bite? Is it like this every time or is it trained to react like this in a specific moment? We have covered every concern and question regarding protection training here. If you have any questions left, ask them in the comment section and we’ll help you out.
