Never liked them.
I've seen many nice ones, but just as many mean ones.
The problem is they have the ability to do a LOT of damage very easily.
I grew up with a friend who had 3 of them, one of them was mean as hell. Had to be chained up behind the barn. It was always mean, even when it was 6 months old.
Anyway some idiot was trespassing on their ranch and the pit got loose, mangled the guy up pretty bad and almost killed him. The attack lasted like 2 minutes. We heard it happen, it was insane. The dog knew the guy was almost dead and was guarding him from us and the parents of my friend. Like it was his prey that he was guarding. One of the craziest things i remember as a kid. The father tried to get the dog away from the hurt kid and it attacked him, his own fucking dog.
I still remember they finally just shot the dog with a rifle.
I just don't get the mentality that comes with these dogs. It's like a thug life status symbol in the bad parts of town. In Los Angeles i literally saw them everywhere. Fucking Cholos and their pits.
