Right let me tell you all something,
A good few years ago there was uproar about rottweilers as they are satans dog etc they were going round biting children what a load off old bollocks(how can you bred a dog for fighting it's impossible you can bred them so they certain characteristics and strong heads.
But at the end it is the owners responsiblity to make sure there dog has the right upbringing all dogs are pack animals and origanate from wild animals so if you encourage there natural insticts you are playing a dangorous game full stop.
They tried to ban rotty's also just a group off people going off on one like always just make sure you keep you pitty under control mybe think about showing how good he is by taking him to shows etc.
