I prefer just about any molosser with natural tails (and ears if applicable). Docked tails and cropped ears on a blocky headed and bodied dog looks strange to me, JMHO. I've only seen one Boerboel in person and I think it wad docked. It was impressive looking, but it smelled like Fritos and looked like it had skin allergies. Function wise, giving the dog its rudder is important for making fast turns. I'll go for natural tails.
