Are you sure it is really "pulling" to the right?

It is quite possible that the steering wheel might not be properly centered, so that when the steering wheel is perfectly straight, the wheels could be pointing to the right. If you were to use the steering wheel position to judge this, you might think it is pulling to the right.

If you go to a flat, open parking lot, go forward, and take you hands off the wheel, does it go to the right?

If you definitely does pull to the right on a flat surface, you should inform the dealership ASAP, to avoid any suggestion that you hit a pothole or something between the time vehicle was returned to you and the time you notified then of an issue. It's possible someone hit a curb or something with it while it was at the dealership and messed-up the alignment.
