Because of his two faced personality he was graced with the name, Dr. Jeckel. He can be very intelligent and calm for a few moments but in the next second he'll turn around and bite you. the only one who he doesn't do this with is his handler and his brother.(mainly because his handler popped his mouth when he bit him for the first time and his brother bit him lol). Jeckel can be a very hard worker once you get through his thick skull that he's not in charge. A natural hardhead but also a good leader....when he wants to be.
