Ray I seen one that looked like it had a drop of bull in it he was a big dangerous looking dog put the shits right up me, the lad that had him was only about 15, an accident waiting to happen.
I've had a Google and seen a few pic's of them fighting they look big awkward cnuts,I'd say they'd struggle moving around in a warzone with all the rubble and stuff.
In a fight in a pit I'd say the bully would kill the Mali but out in the open I couldn't seen them bully's been much use, but I haven't seen either dog in action.
