With that small of a place, you shouldn't go more than 20-25 lbs in size max... Yappers keep burglars away but could irritate your neighbors. And you probably should check your lease first. Some of them are pretty explicit on pets - sizes - breeds etc. They also cna cost some serious bucks in extra deposits.
If you can find one that won't get too big and it's young, sometimes they can be broken to a box. ;-) Older ones will go to a paper sometimes. Larger dawgs are usually the chewers too. We go through 4-5 of those HUGE chew things a week sometimes!!! The neighbors got tired of us letting our dawg chew on them and their cars.
