Overture Demo - Passing the dog

[ChazFox]

Alright, so after having bought the actual game (Having wanted to play more after getting attacked by the dog in the demo) someone has informed me that in the demo, it is in fact possible to block the dog's path and get past them, and someone else informed me that there's a little something waiting for me if I do just that. So now I'm curious. Very curious. Extremely curious in fact, about both how to block the dog and what this little something is. If someone can tell me one or the other, or both, it'd be much appreciated
