There's nothing innate in a pitbull that would make it snap for no reason. It's just that if it does snap it's a mucher bigger problem for you than a Golden snapping. There are more people bitten by Golden's every year than Pits. I'd say a large portion of people that own pits unfortunately have no purpose owning one because it takes a lot of personal responsibility, but that has nothing to do with the dog, it's about the dog's potential if mismanaged.
