Yes it will happen! Our pup was housetrained at about 6 months for both. We have trained her for outside pottying. She caught on to the signals for "pee" quicker than for "poo".
We hung a small windchime beside the door and everytime we took her out we hit it and said "outside". She began to associate the windchime, outdoors, and pottying and pretty soon would "nose" the windchime when she wanted to go out.
The only other tip I have is that I wrote out a schedule so I could see when she needed to go out and then followed that for a while (I'm at home during the day so this worked well).
You'll start noticing your dog's signals soon. For us the signal was pacing.
Good luck!
