All I see here is an animal whose owner(s) have absolutely no control over and a potentially very dangerous situation.
It looks like it has been trained for protection (german term... dachs... something), but i don't know why it looks so dangerous to you. it doesn't seem to be aggressive towards anything it isn't focused on (like the dogs, cats or humans). Shave a field labrador to show its muscle and people would be terrified of that kind of hyper activity.
