You are right, as a major exposure phase is already past you, we are currently on the same situation.
My belief is that any, but ANY dog can be trained to fit your needs, some just may require more effort.
In our case, the dog was in a family, so he came house-adaptable, but that family never took him out for walks (they let him go to the yard), resulting in him being terrified from other human or dog encounters.
After 2 weeks of working on that stuff with him, he immideatly started showing progress, and getting better by the day
What do you think your dog lacked in training up to his current age? where was he and what was his status?
I would also add: think about how much you are helping the dog.
you are already taking on a hard mission, and the older the dog the lesser the chances someone will give him a family he deserves - maybe you can be the one rescuing him.
