A friend has a rescued pittbull who's previous teeth were all broken by the time he was rescued. Perhaps thats what they ment... I guess in some places its a practice to make the dog mean... Koha (the rescue) was supposed to be a "fighting" pittbull... but only didn't have the drive to fight so they figured they would stick him in a basement and break his teeth out. Pretty sad, but his new owners is great. :D
