Just a few words about protection work in sports.

How often, when a dog doesn't obey or doesn’t release the sleeve, do we hear from handlers: “Show her who’s in charge, throw her down,” or “You have to conquer her, otherwise there won’t be any point”? Very often! And what happens as a result? The handler, losing their temper, begins correcting the dog, and this leads to a MASS of problems.

First, the strong dog still won’t submit, or if it does, it will take advantage of the first chance to "snap" back.

Secondly, the bite and release will suffer. The work will become inconsistent.

Thirdly, in the future, there will be a strong distraction to the decoy. And how could it be otherwise? After all, the decoy is the "authority" who gives the punishment! And you need to respect (or even "fear") authority.
