Barking on a hot or cold track is a death sentence for a Cur dog in the south. We use Cur dogs to trail/find, bay, and catch hogs with. Any barking on the track before they get the hog found and stopped sends the hog running to the horizon i.e. long races, lost dogs, and no catch.
Silent trailing is what most Cur dog hog hunters want and need. The preferred and desirable Cur dog hunts and trails silently until the game is found then they bay loudly and keep the hog in one place until help arives. Some Cur dogs are a little mouthy on a hot running track. The mouthy ones are usually culled quick as they can cause the others to start barking.
