Yes but it's still a form of bullying the dog into being where you want it to be!

I used to walk my flatmates very large gsd. He pulled and pulled and we all ended up with burns on our hands from him yanking the lead.
One night I was realy tired and had enough and I whacked him lightly on the nose with the handle, which made a loud slap noise as the handle hit it'self on his nose. It did stop him from yanking my hands off, but he was edgy about it. I felt bad for ages. It didn't cure him though, he was soon back to pulling again!

Dogs are far more likely to learn something if they get pleasure out of it.
Giving a dog treats for being next to you the dog will be happy to be there, and learn quickly.
Smacking the dog on the bum whenever he pulls does not teach him where you want him to be, but teaches him through something unpleasant where you don;t want him to be.

You could end up making the problem worse, make the learning progress longer, even end up with an agressive dog because you are bullying him!

There is no point in correction of that sort, reward based training is much nicer.
