When I first bought my Pit Bull, from a policeman, the woman neighbourish got off her ass and went to complain to my MiL about buying it. She was scared and didn't want it around due to phobia. My MiL wouldn't get involved.
I've had this Pit Bull 7+ years. In that time it has never chased a motorbike, chased a running child, never barks at people, never bit anyone etc etc. But in that time the cow that went to my MiL's dog has done all the previous. She doesn't look after her dog and allows it to attack anyone passing without fear of punishment. But for her to go past my house it's a no no.
