my suggestion would be to hold off on the bulldog while you live in the apartment. i mean, black did post some good points....but IMO, I think your opening up the possibility of future failure.
the things you want to consider is
1. the property is not yours (unless it is, then i apologize)
2. when your lease is up or when it comes time to move your gonna have a hard time finding a place unless you hide the dog, because damn near most places want nothing to do with bully breeds..

if your renting and ok with dodging lndlords and hiding your dog, then....go for it, but ill warn you.....its a BIG PAIN in the ass! ive been there done that.......
