The Guldung is a muscular and powerful Moloss, strongly built and resilient. Deep-chested and with a massive head, this large bulldogge is a rugged and serious working breed, very dog-aggressive and not suited for the life of an urban companion, due to its sharp temperament and wariness of strangers, although it can be very loyal and devoted to its master. Intelligent and alert, the Bully Gull Terr makes a good watchdog, but it requires responsible handling and proper training.
The coat is short, smooth and flat. The only accepted colour for the Gull Dong has traditionally been uniform white, but today other colourings exist as well. Average height is around 27 inches.
