The pitbull breed was created by crossing bulldogs, whose original purpose was bull baiting, and terriers, who are small pest control/hunting dogs that have an extreme prey drive, and then selecting the most aggressive ones for pitfighting. That should be the end of the discussion. They have the naive stubbornness of a bulldog that needs to charge an 800kg bull and the adhd killer instinct for small animals from the terrier. Truly a shit combination and not suitable as pets.
