In most States the hogs are not considered "game" animals and can be hunted by extraordinary means.
I believe the phrase you're looking for in English is "brought to bay" for when a dog frustrates an animal to the point that the animal turns to fight and the dog can hold it in place for the hunter.
I've heard the description of how my "Elkhound" is actually an "Elghund" but in reality he's more of a "grey couch dog".
