That was a good find. I had an ex-GF who watched Cesar M because she owned a German S. Youtube ‘cesar’s worst bites’ and he admits there are lost causes’ of dogs. BTW, by that quote alone, that’s not a pet but a killing machine.
I’ve watched pit bull attack videos and you can’t miss the fact that they are lovin’ it. The tense, warning or fearful behavior of normal dogs before attacking isn’t there. There is the unprovoked attack with no barking or threat. There is gleeful tail wagging like a cat ripping up a toy for fun.
I’ve posted this video before -its a dog racing through a big intersection and pulling down it’s prey, a child walking with an adult. The tail wagging etc. - it never glanced at the other animals (adults), but went for the one it could easily rip apart. Note that this predator believes it can tolerate any pain or agression adults can provide so it is very single minded in its “playful” mauling:

Note how many people had to work to stop it and frankly, the dog gave up more quickly than is usual in many of the reports and videos featuring this breed that I’ve watched and read.
