How are these hunting pens…

How are these hunting pens training domestic dogs the difference between attacking a coyote/fox vs attacking another dog? Once a dog attacks another dog, it generally continues to do so.
Some dogs naturally chase coyotes/predators - such as guardian breeds ( Great Pyrenees etc). But these breeds don’t require these type of hunting pens to know how to do so, it’s instinctual and protects livestock.
This pen idea risks the health and safety of the domestic dog, may inadvertently teach them to attack other dogs and in turn have to be put down, and is animal abuse to both the wildlife and the domestic dog. Ridiculous idea.
