having worked in a vets / boarding /pound I have seen many a dog come though...

we had some pitties who where going though court coz the attacted someone and killed this persons dog.... but they were the sweetest dogs ever always full of love, sadly the way the owner had treaded them ( they were bred for dog fights ) they could not be near any other dogs...

I have seen so many lovely pitty's and staffy's... Its just they fact that they have lock jaw that you have to really watch them as if they do choose to turn on you or another dog ( which is normally the case and then the owners will do something silly like try to pull them apart and this is when the person gets a bite ) they can and will lock their jaw then you cant get them to let go....

to tell you the truth the only does I was every weary of were the cattle dogs they only like their owner and will bite first and think later, I personally think they should stay on the farms where they are meant to be.... and the little rat dogs, it seems the smaller the dog the more likely the little bugger would bite me.... the werid thing is if they do bite you and the owner is there they always just laugh it off almost like it didnt happen, just coz they are small, then of course the silly buggers would just pick their rat dogs up giving the dog what it wanted a reward for biting me....
