I mostly glossed over it as it makes an already complicated arguement even more so...
Even tho bull breeds are trained for animal agression its fairly well known that once their blood is up often they go for anything people or otherwise quite often even their handlers.
Also gets a bit complicated with those others you listed i.e. while Bullmastiffs have been long bred for people aggression Rottweilers are mostly trained for people agression by their owners individually and breeding for such isn't as common (AFAIK isn't part of their "pedigree"), likewise I believe GSDs.
With the greatest respect your ignorance shows, and I don't mean that in a negative way. GSDs and Rotties are
required by the national Kennel Club to pass people-aggression tests in their native land, in order to be allowed to be shown and/or bred from. Many of these dogs are exported and are cornerstones of successful UK lines.
Simply by using terms like 'blood up' you portray your naive understanding of canine psychology. Bull breeds most certainly are not generally indiscriminate in who and what they bite once they are in prey (or even defence) drive. Neither are most other breeds. In fact as I already alluded in my first post, bull breeds are specifically bred to
not become indiscriminate biters when they are in high prey drive, else they'd bite anyone and everyone during work or fights (whether when catching bulls and pigs, or fighting in a match following round-by-round to the old rules). Do you really think the ref or either of the two handlers want to be bitten repeatedly while standing in the box for a couple of hours with two fighting dogs? It simply doesn't work that way.
Actually, Pit Bulls et al. are renowned for keeping their cool under such pressure and this is what makes them celebrated search and rescue dogs, detection dogs, farm dogs, therapy dogs, and even police and war dogs.
As I said I'm not attacking you for your naiveté but it'd be remiss not to point it out. As I said I have over two decades experience keeping, breeding and working bull breeds, guardian breeds and hunting dogs and I can assure you you're founding your assertions on faulty foundations.
