I agree - untrained dogs will revert to their natural instincts, which may be herding, protecting, warning … or attacking, maiming, killing … or anywhere in between. AFAIK, there are now between 10,000 and 30,000 Bully XLs in the UK (1), many of them unregistered - there will, sadly, be more attacks, and even deaths, soon.
A short tale (or tail). Max, my collie, was beautifully behaved. He kept sure where the grandkids were. And me…
One time we were walking home when a couple with their Pit Bulls came on the scene barking. . Max gave them that Collie stare. No barking, just that stare. He sent them on their way.
