yeah i would agree with what you say. the difference being what makes a bandog a bandog is wether its being worked or not. or wether its a working dog. if you crossed an american bully with some other types of mastiff breeds etc. and worked the dogs. why wouldnt they be a bandog.....as a bandog is a working dog usually consisting of mastiff type crosses.....so do you have mastiff type crosses, yes. is the dog being worked, yes. 

my dog is an american bully, crossed with some types of mastiffs. if i start protection work with my dog, would you call him a bandog, or a american bully that does protection work. but i wouldnt call him a pure american bully as hes been outcrossed to mastiff. anyways, a few cop friends of mine have recommended i go to the local bitework class that they offer. i have been meaning to make the trip. ill post some pics when i do.
