Just wondering if you've seen the dog since? I really hope that she's honest with whoever does adopt him, or he'll end up in a shelter for sure
He just needs some training and consistency. Also not a good breed for apartment living unless the owner is super-dedicated to making sure that the dog gets many long walks and playtime at a dog park.
I agree with the post about finding out who insures the building and getting into their ear. This is a continuing and multiple complaint problem, and if they don't do something about it, and someone gets hurt, a lawsuit is sure to follow. And the poor dog would probably be destroyed.
Glad you and Princess are okay, but sorry you have to be scared on your own "turf". Hope it gets settled soon.
